Abstract:
A stent delivery assembly for implanting a stent in a bifurcated vessel having a side-branch vessel and a main vessel, comprising:a dual balloon Y-shaped catheter having a proximal end and a distal end, the catheter including a single catheter shaft joining a pair of relatively short catheter shaft portions, a first expandable member having a proximal end and a distal end and a second expandable member having a proximal end and a distal end; a first lumen for receiving a restraining member, the first lumen extending through at least a portion of the catheter including the first expandable member; a second lumen for receiving a guide wire, the second lumen extending through at least a portion of the catheter including the second expandable member; and a restraining member positioned within the first lumen; wherein the first expandable member and the second expandable member are normally biased apart, but are restrained and held together by the restraining member to provide a low profile during delivery of the stent.
