Stent and catheter assembly and method for treating bifurcations
First Claim
1. A catheter assembly for treating a bifurcated region of a body lumen, comprising:
- a catheter having a proximal end and a distal end;
a first expandable member disposed near the distal end of the catheter;
a second expandable member disposed near the distal end of the catheter;
a first guide wire lumen associated with the first expandable member;
a second guide wire lumen associated with the second expandable member and having a distal end;
a relatively short third guide wire lumen associated with the first expandable member; and
a guide wire extending through the second guide wire lumen and into the third guide wire lumen to releasably connect the first expandable member and the second expandable member.

Abstract
An apparatus and method is provided for stenting bifurcated vessels. A proximal angled stent is configured for implanting in a side-branch vessel wherein the proximal angled stent has an angulated portion that corresponds to the angle formed by the intersection of the side-branch vessel and the main vessel so that all portions of the side-branch vessel at the bifurcation are covered by the proximal angled stent. A main-vessel stent is provided for implanting in the main vessel, wherein the main-vessel stent has an aperture or stent cell that aligns with the opening to the side-branch vessel to permit unobstructed blood flow between the main vessel and the side-branch vessel. Side-branch and main-vessel catheter assemblies are advanced over a pair of guide wires for delivering, appropriately orienting, and implanting the proximal angled stent and the apertured stent.
