Stent

摘要

A stent includes a major axis member which has an internal space extending from a front end portion toward a base end portion, first opening section provided at the front end portion to communicate with the internal space, and second opening section provided at the base end portion to communicate with the internal space, and inflow prevention section which has an inflow prevention surface covering the second opening section with a gap with respect to the second opening section, wherein a first edge section of the inflow prevention surface is fixed to the major axis member closer to a base end than the second opening section, and a second edge section of the inflow prevention surface is disposed closer to a front end than the second opening section and extends from a side surface of the major axis member toward a position spaced apart therefrom outward in a radial direction.

1. A stent comprising:
a major axis member that includes:
an outer circumferential surface having a tubular shape and an internal space that extends from a front end portion to a base end portion of the outer circumferential surface,a first opening section provided at the front end portion of the outer circumferential surface, the first opening section being in communication with the internal space, anda second opening section disposed on the outer circumferential surface, the second opening section being in communication with the internal space; and an inflow prevention section that has an inflow prevention surface covering the entire second opening section,
the inflow prevention section having a first edge section that is fixed nearer to the base end portion side than the second opening section, and a second edge section that is disposed at a position radially spaced from the outer circumferential surface and radially spaced from the second opening section such that the second edge section extends outward in a radial direction from the second opening section.
