Stent for bifurcated vessel

摘要

A stent for a bifurcated vessel includes a stent body (1) with two open ends (5, 6). The stent body (1) includes multiple sets of annular units (2) having multiple undulating rods (4) and connecting rods (3) positioned between adjacent annular units (2) and used to connect the adjacent annular units (2). At least one open end (6) of the stent body (1) has a slope structure.

1. A stent for a bifurcated vessel, comprising:
a stent body having a first open end and a second open end opposite to each other, the stent body comprises:
a plurality of body segments, each of the plurality of body segments including a plurality of wave members connected to each other in an undulating manner;two or more connecting rods positioned between adjacent body segments and configured to connect the adjacent body segments; a slope structure formed at least at the second open end of the stent body, the slope structure having a configuration where (1) compactness of the wave members increases in the direction from the middle part of the stent body toward the second open end, or (2) a number of the wave members in the plurality of body segments decreases and the compactness of the wave members increases in the direction from the middle part of the stent body toward the second open end.
