Document Type and Number:
Japanese Patent JP6880976
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a stent configured to easily remove a string-like member from a stent end portion after expanding a diameter thereof in the stent including a diameter-expansion mechanism that expands the stent diameter by pulling the string-like member attached to the stent end portion and retains it in the diameter-expanded state.SOLUTION: The stent includes: a stent body part 2; and a diameter-expansion mechanism 3A that deforms the stent body part 2 from a diameter-reduced state to a diameter-expanded state and retains it in the diameter-expanded state. The diameter-expansion mechanism 3A includes: a ring-like member 31 to be disposed at a distal end of the stent body part 2; a locking part 32A provided at the proximal end of the stent body pat 2 and projecting toward the proximal end side to be able to lock the ring-like member 31; and a string-like member 33 that is inserted into the ring-like member 31, whose one end is connected to the locking part 32A so as to be removable in a direction of the proximal end side, and whose other end extends toward the proximal end side of the stent body part 2.SELECTED DRAWING: Figure 1
