The device 10 is implemented to be quick and easy to activate by an untrained user. The device 10 generally has three modes of operation including: 1 ) storage, 2) mixing and 3) dispensing. In the storage mode, first and second ingredient materials for making an adhesive material are stored separately from one another in first and second storage chambers, respectively. During the mixing mode, the second material from the second storage chamber is moved to the first storage chamber and the first storage chamber is used as a mixing chamber where the first and second ingredient materials are mixed to form the adhesive material. After the adhesive material has formed, the device 10 is used in the dispensing mode, in which the adhesive material is dispensed to a target area.

[0050] For example, the adhesive material may be a two-part bone cement, such as glass ionomer cements, that can be used for surgical procedures and the target area can be a fractured bone into which the adhesive material is dispensed. For example, the fractured bone may be a fractured human vertebra and the bone cement may be injected into the vertebra during a vertebroplasty operation. In this case, the first ingredient that is stored in chamber 1a can be a powder and the second ingredient that is stored in chamber 1 b can be a liquid. For instance, in one example, the powder can be an ionomeric glass and the liquid can be an aqueous polyacrylic acid. In another example, the powder can be an ionomeric glass and dehydrated polyacrylic acid and the liquid can be water. In another example, the powder can be dehydrated acid and the liquid can be water with dissolved ionomeric glass therein. Accordingly, one of the components, e.g. the acid, the glass or the aqueous media is kept separate until they are mixed in the device 10. Therefore, any two of these components can be supplied premixed but the third component is kept separate from those mixed two components. FIG. 2 shows the chambers 1 a and 1 b.

[0051] While the various embodiments described herein describe the first and second ingredient materials being mixed to form an adhesive material, it should be understood that in at least one alternative embodiment, the first and second ingredient materials can be selected such that when they are mixed they form a third material which is a different kind of material that is not an adhesive material where there third material can be used in other applications.

[0052] The device 10 generally comprises a main housing 12, a first container 14, a nozzle 16, a handle 18 and a handle lock 21 . The handle 18 comprises a finger grip 20 with an aperture 20a and the main housing 12 comprises finger grips 24 and 26 with apertures 24a and 26a respectively. A user may use the finger grips 20, 24 and 26 to hold and use the device 10. The device 10 further comprises a mixer 28 with a mixing element 30 as well as a removable sealing element (i.e. cap) 32. The handle lock 21 can be referred to as a safety release.

[0053] The device 10 can be entirely made of plastic which is sterilizable. For example, the device 10 can be subjected to ultraviolet light or to gamma radiation to sterilize the plastic components of the device 10. [0054] The nozzle 16 is disposed at a first end of the device 0 for dispensing the adhesive material from the device 10 after mixing. The nozzle 16 comprises internal grooves for receiving a portion of the sealing element 32. The nozzle 16 may be sized and shaped so that it is a standard medical fitting that can be attached to a needle, a cannula, a medical tubing or another standard medical fitting for dispensing the adhesive material. For example, in some embodiments, the nozzle 16 can be sized to fit with a 9 gauge needle, a 14 gauge needle or a 16 gauge needle.

[0055] The sealing element 32 is removably attachable to the nozzle 16. The sealing element 32 is disposed and engaged with the nozzle 16 when the device 10 is used for storing and mixing the ingredient materials and the sealing element 32 is removed when the adhesive material is dispensed from the device 10. The sealing element 32 comprises a gripping portion 33 that a user may hold when mounting or removing the sealing element 32 from the nozzle 16. The sealing element 32 further comprises an engagement portion with grooves 33g on an external surface thereof that engage corresponding threads on an interior surface of the nozzle 16. In other embodiments, the sealing element 32 may be a pin and the interior surface of the nozzle 16 can be adapted to receive the pin and make a friction fit with the pin. The sealing element 32 may further comprise a seal 33s that is resilient and compliant, such as an o-ring for example, to provide additional sealing for the nozzle 16.

[0056] The first container 14 is disposed at a distal end of the device 10. The nozzle 16 is coupled with a first end 14a of the first container 14. In this example, the nozzle 16 is an integral portion of the first container 14. A distal portion of the first container 14 has sidewalls that define a first chamber 1 a that is adapted to act as a storage chamber for storing a first ingredient material during the storage mode. The chamber 1 a of the first container 14 is also adapted to act as a mixing chamber to mix the first ingredient material with a second ingredient material to create the adhesive material during the mixing mode. The chamber 1 a is in fluid communication with the nozzle 32 to allow the adhesive material to be dispensed from the device 10 during the dispensing mode.

[0057] The first container 14 is in the form of a cylinder in this example embodiment and can be referred to as a first cylinder or a forward cylinder. The first container 14 comprises a mid-portion with a flange 14b that flares outwards and has an internal circumferential groove 14g. The side walls of the first container 14 further extend past the flange 14b to provide a guide region 14c in a proximal portion of the first container 14 where the side walls have two guide channels 15c that are formed along a portion thereof in the guide region 14c. The guide region 14c ends with a second flange 14f. The diameter of the side walls of the first container 14 that form the first chamber 1 a and the diameter of the side walls are the guide region 14c are the same or substantially similar.

[0058] The device 10 further comprises a second container 34 that is disposed within the first container 14 and moveable therein. The second container 34 comprises a second chamber 1 b that acts as a storage chamber for the second ingredient material. The second container 34 comprises a first end 36 with an aperture 36a and a sealing member 36s disposed adjacent to the first end 36 and extending circumferentially around the second container 34. The aperture 36a is in fluid communication with the first container 14. The sealing member 36s is resilient and compliant and may be an o-ring.

[0059] The second container 24 further comprises a guide region 35 formed by sidewalls at a proximal portion thereof and protrusions 37t that are adjacent a second end of the second container 34. The protrusions 37t are on the exterior of the walls of the second container 34 and are sized to slidingly engage the guide channels 15c of the first container 14. In this example embodiment, the protrusions 37t are formed by posts. The protrusions 37t have a height that is larger than the thickness of the side walls of the guide region 15c of the first container 14 so that the protrusions 37t can extend past the sidewalls of the first container 14 during use. [0060] The second container 34 is in the form of a cylinder and may be referred to as a middle container. The sidewalls of a distal portion of the second container 34 define the second chamber 1 b. The exterior side walls of the second container 34 are sized to be slightly narrower than the side walls of the guide region 14c of the first container 14 (i.e. the diameter of the second container 34 is smaller than diameter of the first container 14). This allows the second container 34 to slide within the guide region 14c of the first container 14 and be moveable with respect to the first container 14. The second container 34 is moveable within the first container 14 between a storage position in which the second ingredient material is stored in the chamber 1 b of the second container 34 and a mixing position in which the second ingredient material is moved through the aperture 36a into the first container 14. The first chamber 1 a extends from the inner surface of the distal end 14a of the first container 14 to the exterior of the end 36 of the second container 34.

[0061] In this example embodiment, the length of the second container

34 is smaller than the length of the guide region 14c of the first container 14, which allows the second container 34 to be fully contained within the first container 14 during the storing, mixing and dispensing modes as is shown in FIGS. 3-6, for example. In alternative embodiments, the length of the second container 34 may be larger or the same size as the length of the guide region 14c of the first container 14 to increase or decrease, respectively, the size of the mixing chamber during the mixing mode.

[0062] The sealing member 36s engages the internal surfaces of the side walls of the first container 14 for providing sealing for the first chamber 1 a so that the first and second ingredients, during the mixing mode, or the adhesive material, during the dispensing mode do not leak from the mixing chamber past the second container 34 during use. This stops air (oxygen) and water from entering/exiting the chamber 1 a (which may degrade the ingredients) and prevents the two ingredients from mixing prematurely.

[0063] In this example embodiment, the first and second containers 14 and 34 are made of transparent material which allows for visual inspection of the first and second ingredient materials during the storage and mixing modes. For example, the user can observe the purity and quality of the two ingredients prior to mixing and during mixing as well as observe the consistency of the adhesive material which will help in determining if the ingredient materials have been mixed together sufficiently. That being said, in other embodiments, the materials used to make the first and second containers 14 and 34 may not be transparent.

[0064] The mixer 28 longitudinally extends into the first and second containers 14 and 34 and is used to mix the first and second ingredient materials. The mixer 28 comprises a shaft (i.e. rod) having a first distal portion 28a and a second proximal portion 28b. The mixer 28 further comprises a mixing element 30 disposed at an end of the distal portion 28a, mixing grooves 29a (i.e. mixing slots) on an exterior surface of the distal portion of the mixer 28 but closer to the midpoint of the mixer 28. The mixer 28 further comprises a seal 27 at a mid-portion thereof and an engagement portion 29b at a proximal end of the proximal portion 28b of the mixer 28. The seal 27 is resilient and compliant and may be a sealing ring such as an o-ring, for example. The seal 27 provides a seal between the mixer 28 and the aperture 36a during the dispensing mode.

[0065] The mixing element 30 is disposed within the mixing chamber 1 a of the first container 14 for mixing the first and second ingredient materials. The mixing element 30 is rotatable (see arrows 6r in FIG. 5) and longitudinally translatable within the mixing chamber 1 a for mixing the first and second ingredient materials. Accordingly, the shaft of the mixer 28 is sized to slidingly move through the aperture 36a of the second container 36. The mixing element 30 is larger than the aperture 36a and the nozzle 16 such that its motion is constrained within the chamber 1 a.

[0066] The mixing grooves 29a allow for the second ingredient material to move through the aperture 36a from the second container 34 to the first container 14 during the mixing mode as is shown by arrows 6b and 6c in FIG. 5. This is because during an initial portion of the mixing mode, a first portion of the mixing grooves 29a are disposed within the first container 14 and a second portion of the mixing grooves 29b are disposed within the second container 34 as shown in FIG. 5 to allow the second ingredient material to move from the second container 34 to the first container 14.

[0067] In this example embodiment, there are two mixing grooves 29a that are in the shape of rectangular slots that are on opposite portions of the surface of the mixer 28. In alternative embodiments, there may be more or less mixing grooves and they may have different shapes compared to one another and/or shapes that are different than a rectangular shape.

[0068] The engagement portion 29b of the mixer 28 engages a portion of the handle 18. This allows a user to control the mixer 28 by moving the handle 18. In this example embodiment, the engagement portion 29b comprises has two slots in the distal portion 28b of the mixer 28 that form a neck portion and a club or head adjacent to the slots.

[0069] The device 10 further comprises a third cylinder 38 that may be referred to as a rear cylinder. The cylinder 38 is moveable with respect to the second container 34. Accordingly, the rear cylinder 38 has a diameter that is smaller than that of the second container 34. The rear cylinder 38 comprises an aperture 40a at a distal end 40, an axial channel 38c, a sealing member 38s, protrusions 4 1 and a proximal end 39 with an aperture 39a.

[0070] The rear cylinder 38 is moveable between a storage position (see FIG. 3) and a mixing position (see FIG. 6). In the storage position, the second ingredient is stored in the second chamber 1 b of the second container 34 and a distal portion of the rear cylinder 38 is received within the guide region 35 of the middle cylinder thereby defining the size of the second chamber 1 b. The second chamber 1 b extends from the inner surface of the distal end 36 of the second container 34 to the exterior of the end 40 of the rear cylinder 38. In the mixing position, the rear cylinder 38 is moved further into the second container 34 to provide a force that moves the second ingredient through the aperture 40a into the first container 14. In at least some embodiments, in the mixing position, the rear cylinder 38 is nested within the second container 34 and the second container 34 is nested within the first container 14 since all three cylinders 14, 34 and 38 are concentric and have progressively smaller diameters when moving from the distal end to the proximal end of the device 10.

[0071] The sealing member 38s is disposed around a circumference of the sidewalls of a distal portion of the cylinder 38 adjacent to the end 40. The sealing member 38s engages the internal surfaces of the side walls of the second container 34 for providing sealing for the second chamber 1 b so that the second ingredient, during the storage or mixing modes, does not leak from the second chamber 1 b past the rear cylinder 38 during use. The second sealing member 38s is resilient and compliant and may also be an o-ring. The sealing member 38s stops air (oxygen) and water from entering/exiting the chamber 1 b (which may degrade the ingredients) and prevents the two ingredients from mixing prematurely.

[0072] The axial channel 38c runs along the length of the rear cylinder 38 between the ends 39 and 40 and is aligned with the aperture 40a. The diameter of the axial channel 38c is large enough to receive the shaft 28b of the mixer 28. The proximal portion of the mixer 28 is disposed within the axial channel 38c such that the engagement portion 29b of the mixer 28 extends past the aperture 39a to engage a portion of the handle 18 and the distal portion 28a of the mixer 28 extends past the aperture 40a.

[0073] The protrusions 411 are disposed on an exterior surface of the second container 38 adjacent to the proximal end 39 of the second container 38. The protrusions 411 are posts that are similar to the protrusions 37t of the container 34 and are sized to slidingly engage the guide channels 15c of the first container 14 in the same way as protrusions 37t.

[0074] The proximal end 39 of the rear cylinder 38 has a flat annulus that defines the aperture 39a and provides a surface for receiving a distal portion of the handle 18 when a male locking member 22 of the handle lock 21 is removed (see FIGS. 7B-7C) which allows the handle 18 to move the rear cylinder 38 towards the first and second containers 14 and 34. A portion of the handle 18 engages (i.e. pushes against) the end 39 of the rear cylinder 38 during the mixing and dispensing modes when the male locking member 22 is removed.

[0075] In this example embodiment, the length of the rear cylinder 38 is the slightly smaller than the length of the second container 34 which allows the rear cylinder 38 to be fully contained within the second container 34 during the mixing and dispensing modes. Accordingly, the protrusions 411 abut against the protrusions 37t of the second container 34 when the rear cylinder 38 slides as far as possible within the second container 34. In alternative embodiments, the length of the rear cylinder 34 may be larger or smaller than the length of the second container 34 to increase or decrease, respectively, the size of the second chamber 1 b during the storage mode.

[0076] The handle 18 is located at a proximal end of the device 10. The handle 18 is coupled to the mixer 28 to mix the first and second ingredient materials. The handle 18 is also coupled to the rear cylinder 38 which is used to move the second container 34 to a dispensing position to dispense the mixed adhesive material. The handle 18 comprises a hollow shaft with an axial channel 19 that extends longitudinally along at least a portion of the handle 18 to a distal end 18a having a flange 18f. In some embodiments, the axial channel 19 can also extend to a proximal end 18e of the handle 18 that is adjacent to the finger grip 20. The finger grip 20 comprises a ring with an aperture 20a. The handle 18 further comprises a groove 18g that extends along an exterior surface of the handle 18 to the proximal end 8e. A distal end of the groove 18g ends in an aperture 18c that opens into and is connected with the axial channel 19. The groove 18g and the aperture 18c are adapted to receive the male locking member 22 of the handle lock 21 . In some embodiments, small ribs may be used in the groove 18g and/or in the ring 20 to retain the male locking member 22 in place. In some embodiments, the male locking member 22 may be a tear-off or break-away component, so that it cannot be reattached or reset after it is removed.

[0077] The removable handle lock 21 is disposed at the handle 18 and extends along a portion of the surface of the handle 18. The handle lock 21 comprises a male locking member 22 and a female locking member 42. When the handle lock 21 is in place the male locking member 22 engages the female locking member 42, and movement of the handle 18 is allowed along a mixing pathway MP (see FIG. 6) to move the mixer 28 to mix the first and second ingredient materials. When the handle lock 22 is removed and the male locking member 22 is disengaged from the female locking member 42, movement of the handle 18 is allowed along a dispensing pathway DP (see FIG. 7C) to move the second container 34 to the dispensing position in which the second container 34 is moved further into the first container 14 for dispensing the adhesive material through the nozzle 16 when it is ready to be dispensed.

[0078] The male locking member 22 is removably disposed along the groove 18g of the surface of the handle 18. The male locking member 22 comprises a shaft 22b with a handle 22c at the proximal end of the shaft 22b and a post 22e at the distal end of the shaft 22b. The handle 22c is a finger grip with an aperture 22a. The finger grip is a ring. In some alternative embodiments, the finger grip may have another shape. The handle 22c is disposed within the finger grip 20 of the device 10. The post 22e is sized to be slidingly received by the aperture 18c on the handle 18 and to be slidingly received by an aperture 42a on the female locking member 42. The post 22e engages the aperture 8c of the handle 18 and the aperture 42a of the female locking member 42 to constrain the movement of the handle 18 along the mixing pathway. The handle 22c is used by the user to remove the male locking member 22 from the groove 18g and the aperture 18c on the handle 18.

[0079] The female locking member 42 is shaped and sized to be received within the interior axial channel 19 at the distal portion of the handle 18. The female locking member 42 comprises the aperture 42a near a proximal end thereof that aligns with the aperture 18c of the handle 18 for coupling with the male locking member 22. The female locking member 42 further comprises an engagement portion 42b at a distal end for coupling with the engagement portion 28b of the mixer 28. The engagement portion 42b comprises a slot that is shaped to receive the engagement portion 28b of the mixer 28. In this example embodiment, the engagement portion 28b of the mixer 28 has a T-shape and the engagement portion 42b of the female locking member 42 is a similarly sized T- shaped slot. Once the mixer 28 is coupled to the female locking member 42 it is not removable unless the housing 12 of the device 0 is dismantled.

[0080] When the female locking member 42 is engaged with the mixer 28, the distal end of the female locking member 42 abuts against the face 39 of the rear cylinder 38 which allows the user to move the handle 18 and thereby move the rear cylinder 38 between its different operating positions as explained previously. The amount of distance that the user can move the rear cylinder 38 depends on whether the male locking member 22 is engaged with the female locking member 42 (i.e. the post 22e of the male locking member 22 is slid within the aperture 42a of the female locking member 42).

[0081] When the male locking member 22 is engaged with the female locking member 42, the proximal end of the female locking member 42 is fixed in position and does not extend distally past the distal end 18a of the handle 18 as is shown in FIG. 3. Since the engagement member 29b of the mixer 28 is engaged with the engagement portion 42b of the female locking member 42, the mixer 28 is fixed to the female locking member 42 and in turn fixed to the handle 18. When the handle 18 is pushed towards the distal end of the device 10, the motion of the handle 18 is stopped by the mixing element 30 abutting against the distal end 14a of the first container 14 as is shown in FIG. 3.

[0082] When the male locking member 22 is removed, the female locking member 42 is free to move within the handle 18 which allows the handle 18 to move axially independently of the mixer 28. The flange 18f at the distal end 18a of the handle 18 can therefore directly engage the face 39 of the rear cylinder 38 when the user moves the handle 18 towards the housing 12. The handle 18 is not constrained by the mixing element 30 abutting against the distal end 14a of the first container 14 since the female locking member 42 moves proximally inside the axial channel 19 of the handle 18 (see FIGS. 7C and 7D). Therefore, the handle 8 is allowed to move along the dispensing pathway DP (see FIG. 7C) where the distal portion of the handle 18 pushes the rear cylinder 38 and the second container 34 further into the first container 14 which applies pressure to the mixed adhesive material so that the user can dispense the mixed adhesive material from the device 10 as required. Since the distal portion 18a of the handle 18 only presses on the rear and middle cylinders 38 and 34, and does not connect with them, the user cannot draw the mixed adhesive material back into the device 10, which is beneficial since being able to draw the mixed adhesive material back into the device 10 is undesirable. The user can only apply positive pressure to the mixed adhesive material.

[0083] The housing 12 is disposed at a mid-portion of the device 10 with a portion of the first container 14 extending past a distal end 12d of the housing 12 and a portion of the handle 18 extending past the proximal end 12e of the housing 12. The distal end 12d comprises a neck portion that is adapted to engage the internal circumferential groove 14g of the flange 14b of the first container 12. The proximal end 12e has a truncated conical shape with a sloping edge that slopes towards the handle 18.

[0084] The housing 12 comprises two curved portions 12a and 12b that together form a cylindrical body for the device 10. The housing portions 2a and 12b comprise apertures 12c for receiving fasteners for attaching the housing portions 12a and 12b to one another. In one embodiment, the fasteners can be screws so that the housing portions 12a and 12b can be removably secured to one another. Alternatively, in some embodiments, the fasteners can be pins or bolts that are not removable so that the housing 12 cannot be taken apart after the device 10 is constructed.

[0085] The housing 2 further comprises first and second finger grips 24 and 26 that are disposed opposite one another on different sides of an exterior surface of the housing portions 12a and 12b. The finger grips 24 and 26 are rings that have apertures 24a and 26a, respectively. The handle 18 further provides the third finger grip 20. The finger grips 24 and 26 are sized to receive the forefinger and middle finger of a user while the finger grip 20 is sized to receive the users thumb. This allows the user to hold the device 10 with one hand and provide an increased force when moving the handle 18 towards the housing 12 as the user is using both of their fingers to apply a pulling force and their thumb to apply a pushing force and both of these forces together result in a larger contractive force. The ability of a user to easily provide an increased amount of force when using the finger grips 20, 24 and 26 of the device 10 is advantageous when dispensing an adhesive material that is particularly dense and has a high viscosity.

[0086] Both the first container 14 and the second container 34 are rotatable with respect to the housing 12 for mixing the first and second ingredient materials. For example, when the device 10 is assembled, the neck 12d of the housing portions 12a and 12b is adjacent to and received in the circumferential groove 14g such that the first container 14 can rotate with respect to the housing 12.

[0087] Referring now to FIG. 4, the housing 12 comprises inclined grooves 12g on inner surfaces of the two housing portions 12a and 12b. The inclined grooves 12g may also be referred to as guide grooves or guide ramps. The inclined grooves 12g are engaged by the posts 37t of the second container 34 as well as the posts 411 of the rear cylinder 38. In particular, the posts 37t and the posts 411 radially extend past the sidewalls in the guide portion 4c of the first container 14 when the second container 34 and the rear cylinder 38 are disposed within the proximal portion of the first container 14 so that the posts 37t and 411 extend into and engage the inclined grooves 12g of the inner surface of the housing 12. Accordingly, the second container 34 and the rear cylinder 38 move axially with respect to the first container 14.

[0088] During use, when the first container 14 is twisted, via a twisting motion 4r, relative to the housing 12 this causes the posts 37t of the second container 24 to move along the inclined grooves 12g of the housing 12 which causes the second container 34 to rotate. At the same time the posts 37t are engaged within the linear guide channels 5c of the first container 14 which causes the second container 34 to move linearly away (see arrows 6a in FIG. 5) from the first container 14 such that the mixing grooves 29a are now disposed in both the first and second containers 14 and 34. At the same time the second container 34 moves closer to the rear cylinder 38 which reduces the size of the storage chamber 1 b which causes the second ingredient material to then move (see arrows 6b and 6c in FIG. 5) along the mixing grooves 29a from the storage chamber 1 b of the second container 34 into the chamber 1 a of the first container 14. The chamber 1 a now acts as a mixing chamber as is shown in FIGS. 5 and 6. The chamber 1 a is now enlarged since the second container 34 has moved away from the first container 14.

[0089] The grooves 12g along the interior surface of the housing 12 comprise a hook-shaped stop portion 12s, which constrains the motion of the posts 37t thereby stopping the rotational and linear motion of the second container 34. The distance that the second container 34 moves away from the first container 14 is set by the shape, length and angle of the inclined grooves 12g and can be selected such that the size of the chamber 1 a increases to be the size of the chamber 1 b plus the original size of the chamber 1 a (when it was used for storing the first ingredient during the storage mode) and the size of the second chamber 1 b can become zero or minimal when the second container 34 stops moving. The interaction between the inclined grooves 12g and the protrusions 37t and 411 are such that the activation process (i.e. the mixing of the first and second ingredients) is irreversible and cannot be reset or stopped once initiated so the device 10 cannot accidentally be used twice.

[0090] It should be noted that the movement of the first and second containers 14 and 34 and the mixing of the first and second ingredients can be done while the device 10 is still locked and the handle lock 21 is still in place. When the adhesive material is prepared and is ready for use, the male portion of the handle lock 21 can then be removed so that the handle 18 can be further actuated to dispense the adhesive material from the nozzle 16 of the device 10.

[0091] The device 10 can be implemented such that the size of the first and second chambers 1 a and 1 b can be varied so that they hold sufficient amounts of ingredients that are needed to make an amount of adhesive material that is sufficient for the application for which the device 10 is used. For example, when the device 10 is used to hold reagents that are used to formulate a bone cement, the chamber sizes 1 a and 1 b, and therefore the amount of the reagents, can be implemented to be larger, such as 10 cm 3 for example, when a larger amount of bone cement is needed such as for knee or shoulder surgery, for example, whereas the chamber sizes 1 a and 1 b can be implemented to be smaller, such as 4 or 5 cm 3 for example, when a smaller amount of bone cement is needed such as for wrist surgery, for example.

[0092] In an example embodiment, the device 10 can be implemented such that it has an overall length of 210 mm, an overall height of 85.6mm, and an overall width of 37.6mm. Furthermore, the device 10 can be implemented so that the volume of chamber 1 a during storage is 6.2 cc, the volume of chamber 1 b during storage is 4.8 cc and the volume of chamber 1 a when it is enlarged and used for mixing is 1 1 cc.

[0093] Referring now to FIG. 8A, illustrated therein is a flowchart of an example embodiment of a method 100 for making the device 10 for storing first and second ingredient materials, mixing the ingredient materials to form an adhesive material and dispensing the adhesive material in accordance with the teachings herein.

[0094] At act 102, the method 100 comprises inserting the first ingredient material into a first chamber 1 a of a first container 14 having a nozzle 16 at a distal end and an open proximal end, the nozzle 16 being sealed by a removable sealing member 32.

[0095] At act 104, the method 100 comprises inserting a mixer 28 having a mixing element 30 on a distal end thereof longitudinally through an aperture on a distal end of a second container 34 having a second chamber 1 b and an open proximal end;

[0096] At act 106, the method 100 comprises inserting a distal end 36 of the second container 34 into the first container 14 with the mixing element 30 on the distal end 28a of the mixer 28 extending into the first chamber 1 a. The first and second containers 14 and 34 have a linear translational coupling that allows the second container 34 to move relative to the first container 14 and the rear cylinder 38. The linear translation coupling comprises the guide channels 15c on the guide portion 14c of the first container 14 and the protrusions 37t on the outer surface of the proximal end portion of the second container 34.

[0097] At act 108, the method 100 comprises inserting the second ingredient material into the second chamber 1 b of the second container 34.

[0098] At act 110, the method 100 comprises inserting a distal end of a rear cylinder 38 into the second container 34 where the rear cylinder 38 has an axial channel 38c. The rear cylinder 38 is inserted into the second container 34 until the proximal end of the mixer 28 extends past a proximal end of the rear cylinder 38. The rear cylinder 38 and the first container 14 have a linear translational coupling that allows the rear cylinder 38 to move relative to the first container 14. The linear translation coupling comprises the guide channels 15c on the guide portion 14c of the first container 14 and the protrusions 411 on the outer surface of the proximal end portion of the rear cylinder 38.

[0099] At act 1 12, the method 100 comprises coupling the handle 18 with the handle lock 21 to the proximal end of the mixer 28 and to a proximal portion of the rear cylinder 38 using two coupling steps. For example, a female locking member 42 of the handle lock 21 is releasably coupled with the engagement portion 29b of the mixer 28 by engaging the female locking member 42 with the male locking member 22. In addition, the flange 18f of the distal end 18a of the handle 18 makes contact with the proximal face (e.g. annulus 39) of the rear cylinder 38.

[00100] At act 1 14, the method 100 comprises mounting a housing 12 around a proximal portion of the first container 14 and a distal portion of the handle 18. The housing 12 and the first container 14 have a rotational coupling (via the flange 14b with the circumferential groove 4g and the neck 12d of the housing 12). The housing 12 and the second container 34 as well as the rear cylinder 38 have a rotational and linearly translational coupling due to the inclined grooves 12g (on inner surfaces of the housing 12) being slidingly engaged by the protrusions 37t on the second container 34 and the protrusions 411 on the rear cylinder 28. [00101] It should be noted that after act 1 14, when the ingredients have been stored and the device 10 has been assembled, the device 10 can be put into a sterilized bag or pouch that may also be sealed. Therefore, the device can be p re-filled with the first and second ingredients, put into a sterilized bag and then stored for periods of up to about one year before use if the sealing components of the device 10 and the sterilized bag provide adequate sealing.

[00102] Referring now to FIG. 8B, shown therein is a flowchart of an example embodiment of a method 150 of using the device 10 for mixing first and second ingredients to form an adhesive material and dispensing the adhesive material, where the device 10 is defined according to any of the embodiments described in accordance with the teachings herein.

[00103] At act 152, the method 150 comprises the user rotating the first container 14 relative to the housing 14 of the device 10. When the user twists the first container 14 in this manner, this causes the protruding features 37t and 411 on the second container 34 and the rear cylinder 38, respectively, to interact with the inclined grooves 12g on the inner surfaces of the housing portions 12a and 12b (see FIG. 4) which moves the second container 34 towards the rear cylinder 38. As the second container 34 moves towards the rear cylinder 38, the sealing member 36s that separates the storage chambers 1 a and 1 b passes over one or more mixing grooves (i.e. slots) 29a in the mixer 28. The mixing grooves 29a allow the second material to by-pass the sealing member 36 and move from the second storage chamber 1 b into the first storage chamber 1 a (see FIG. 5). In the case of bone cement, in an example embodiment, a liquid component in the second chamber 1 b moves from the second storage chamber 1 b into the first storage chamber 1 a so that the two reactive parts of the bone cement are introduced together.

[00104] It should be noted that in an alternative embodiment, there may be only one protrusion 37t on the second cylinder 34, only protrusion on the rear cylinder 38, only one guide groove 5g on the first cylinder 14 and only one inclined groove 12g on the inner surface of the housing 12. [00105] In some embodiments, the device 10 may be in a sealed sterile storage pouch so prior to rotating the first container 14, the user removes the device 10 from the sterile storage pouch in preparation for use.

[00106] In some embodiments, prior to rotating the first container 14, the user may also move the mixer 28, which is connected to the handle 18, to agitate the first ingredient material that is in the first storage chamber 1 a. For example, when the first ingredient material is the powder component of a bone cement, caking of the powder may have occurred during storage, and so some initial agitation of the powder before use may be done to improve the mixing of the powder with the liquid ingredient material.

[00107] At act 154, the method 150 comprises the user using the mixer 28 to sufficiently and thoroughly mix the first and second ingredient materials for forming the adhesive material. The mixing can be done by simply moving the mixer 28, by using the handle 18, backwards and forwards. In addition, the handle 18 may be rotated to rotate the mixer 28. The mixer 28 has a mixing element 30, which in this example is a cross-shaped element, on the end of the mixer 28 that passes through the two ingredient materials forcing them to mix together. This direct mixing action provides the user, through the handle 8 and the mixer 28, with tactile feedback to indicate the consistency of the mixed adhesive material. The transparent portion of the container 14 provides the user with visual feedback of the mixed adhesive material in the chamber 1 a. The user can then use this tactile feedback and/or visual feedback to determine whether further mixing is required. For example, when the adhesive material is a bone cement, the adhesive material becomes stiffer when it is sufficiently mixed and it is useful to understand when this occurs.

[00108] At act 156, the method 150 comprises the user removing the male locking member 22 of the handle lock 21 by using a pulling force 7a. When the male locking member 22 is removed, the handle 18 is disconnected from the mixer 28 (see FIGS. 7A-7C). At this point, the handle 18 is now capable of moving the rear cylinder 38 into a further distal position. [00109] At act 158, the method 150 comprises the user removing the removable sealing element 32 from the nozzle 16 of the device 10 by applying a removal force 7b which may be a pulling force or a rotating force depending on the implementation of the sealing element 32. The removal of the sealing element 32 (which in this example embodiment is a sealing cap) allows the adhesive material to exit from the chamber 1 a (that was acting as a mixing chamber) and to exit from the device 10.

[00110] At act 160, the method 150 comprises the user applying forces 7c and 7d (see FIGS. 7C-7D) to move the handle 18 towards the housing 12 of the device 10 to dispense the adhesive material. It should be noted that another force can be applied in a direction opposite to force 7c when the user's forefinger and middle finger pull back on the finger grips 24 an 26. The user may apply force to eject the adhesive material from the device 10 and the user can determine how well mixed the adhesive is by observing how the adhesive material moves upon application of the ejection force.

[00111] The device 10 is not intended to be reused, so once a sufficient amount of the adhesive material has been dispensed no further interaction is required. When the adhesive material is bone cement, any unused or residual bone cement will quickly set and prevent reuse of the device 10. In some embodiments, the user may attach the nozzle 32 to a needle, a cannula, a medical tubing or another standard medical fitting prior to dispensing the adhesive material.

[00112] It should be noted that as soon as the two ingredient materials are mixed sufficiently to form the adhesive material the user may have a limited amount of time to dispense the adhesive material before it becomes no longer useable. For example, in the case of mixing the ingredient materials to form bone cement as the adhesive material, the bone cement has a limited lifetime before it becomes unworkable and sets solid. Advantageously, the device 10 is constructed so that it is quick and simple to dispense the adhesive material.
