Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
157 words
A stent delivery catheter assembly for treating bifurcated vessels 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 first expandable member having a proximal end and a distal end, the catheter further including a second expandable member having a proximal end and a distal end; a first guide wire lumen for receiving a first guide wire, the first guide wire lumen extending through at least a portion of the catheter including the first expandable member; a second guide wire lumen for receiving a second guide wire, the second guide wire lumen extending through at least a portion of the catheter including the second expandable member; and a Y-shaped stent; wherein the first expandable member and the second expandable member are normally biased apart, but are restrained and held together to provide a low profile during delivery of the Y-shaped stent.
Claim 2
Dependent Claim
157 words
A stent delivery catheter assembly for treating bifurcated vessels 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 first expandable member having a proximal end and a distal end, the catheter further including a second expandable member having a proximal end and a distal end; a first guide wire lumen for receiving a first guide wire, the first guide wire lumen extending through at least a portion of the catheter including the first expandable member; a second guide wire lumen for receiving a second guide wire, the second guide wire lumen extending through at least a portion of the catheter including the second expandable member; and a Y-shaped stent; wherein the first expandable member and the second expandable member are normally biased apart, but are restrained and held together to provide a low profile during delivery of the Y-shaped stent.
Claim 3
Dependent Claim
22 words
The stent delivery assembly of claim 1 , wherein the Y-shaped stent is removably mounted on the first and second expandable members.
Claim 4
Dependent Claim
45 words
The stent delivery assembly of claim 1 , further including a removable locking ring for assisting in holding the first expandable member and the second expandable member together at distal ends of the first and second expandable member prior to implantation of the Y-shaped stent.
Claim 5
Dependent Claim
33 words
The stent delivery assembly of claim 1 , wherein the first guide wire lumen includes a distal section, a portion of which extends through at least a portion of the second expandable member.
