Title:
DELIVERY DEVICE AND DELIVERY DEVICE WITH INDWELLING TOOL
Document Type and Number:
Japanese Patent JP2022143216
Kind Code:
A
Abstract:
To provide a delivery device capable of suppressing kink of a sheath by facilitating the setup of a bent state of the sheath, and delivery device with an indwelling tool.SOLUTION: A delivery device includes a sheath 3 and an operating line 4. A distal end 3a of the sheath 3 is, in a natural state, is shaped into a bent state with a first folding point 3c formed at one side in the opposite side of the other side in a radial direction where the operating line 4 is disposed. The sheath 3 is so configured a hardness of at least a part of a distal end-side region (a second region 3f and a third region 3g) located in a distal end side with respect to a first region 3e is lower than a hardness of at least a part of a proximal end-side region (the first region 3e) located at the proximal end side of the first folding point 3c. The sheath 3 includes a second folding point 3d to be a folding point when the operating line 4 is pulled, at the proximal end side of the sheath 3 with respect to a tip end 4a of the operating line 4.SELECTED DRAWING: Figure 2
