Abstract
Abstract An improved catheter assembly and method are provided for treating bifurcated vessels. The catheter assembly of the present invention includes a tubular sheath for restraining dual balloons normally biased apart. Withdrawal of the sheath allows the balloons to separate and deploy intravascular stents in a bifurcated vessel. The catheter assembly also includes the feature of containing two guide wire lumens in a single catheter designed to track over a single wire prior to arrival at the bifurcation, thus preventing wire wrapping and crossing of the wires.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
138 words
A method of stenting a bifurcated vessel having a bifurcation, a first vessel branch, and a second vessel branch, comprising the steps of: providing a dual balloon Y-shaped catheter having a first expandable member and a second expandable member; providing a Y-shaped stent mounted on the first and second expandable members; providing a tubular member and placing it about the first and second expandable members such that the first and second expandable members are normally biased apart, but are restrained and held together by the tubular member; delivering the Y-shaped stent to a target area; withdrawing the tubular member proximally until the first expandable member and the second expandable member are released and spring apart; implanting the Y-shaped stent by inflating the first and second expandable members; deflating the first and second expandable members; and withdrawing the catheter.
