Document Type and Number:
WIPO Patent Application WO/2023/022104
Kind Code:
A1
Abstract:
A medical elongated body 1 comprises: an inner wire 10; an engaging part 60 provided to the outer periphery of the inner wire 10; a cylindrical body 20 provided to the outside of the inner wire 10 and movable along the axial direction of the inner wire 10; and a connector part 30 that is attached to the base end of the cylindrical body 20 and has a lumen into which the inner wire 10 is inserted. A lumen 310 of the connector part 30 is provided with an engaged part 311 that, when the cylindrical body 20 is moved in a direction toward a tip end of the inner wire 10 along the axial direction of the inner wire 10, engages with the engaging part 60 to restrict further movement of the cylindrical body 20 in the direction toward a tip end of the inner wire 10. With this type of medical elongated body, there is no need to additionally use a micro-catheter or the like when inserting a large-diameter catheter to a target position, and it is also possible to realize a smooth structure having a gradual rigidity change from the tip end to the base end.
