Title:
H-SIDE BRANCH STENT
Document Type and Number:
WIPO Patent Application WO/2010/131823
Kind Code:
A1
Abstract:
The present invention relates to an H-side branch stent, and more specifically, to an H-side branch stent comprising: a first stent having a hollow cylindrical shape and having a plurality of cells; one or more bridges having one end thereof connected with a terminal end of the first stent; and a second stent having a hollow cylindrical shape, having a plurality of cells, and having the front end thereof connected with the other end of the bridge. The H-side branch stent of the present invention prevents restenosis of bifurcated blood vessel opening by fully supporting the inner circumference of the bifurcated blood vessel opening in a circumferential direction. In addition, since the stents are not concentrated at the boundary between a main blood vessel and a bifurcated blood vessel or some part of the stent in the main blood vessel is not protruded, bloodstream disorder can be prevented.
