Abstract
A Y-shaped stent, or bifurcated stent, for stenting bifurcated vessels consists of a first generally cylindrical distal branch defining a first flow path for fluid flow, and a second generally cylindrical distal branch defining a second flow path for fluid flow. The first and second distal branches are interconnected by one or more bending elements at a carina junction, each of the bending elements being flexible such that the first and second distal branches are capable of pivoting about the bending elements at the carina junction, thus defining an angle of varying degree. A generally cylindrical proximal branch defines a third flow path for fluid flow. The proximal branch is attached to the first and second distal branches proximate the carina junction such that the first and second distal branches and the proximal branch are in communication with each other.
