Patent ID: 7125419

Claim:
A method of treating a vascular bifurcation of a proximal main vessel into a first and a second distal branch vessels, comprising the steps of: providing a delivery catheter having a first stent thereon, the first stent having a proximal, upstream end and a distal, downstream end and being self expandable to a configuration having a single central lumen in which the proximal, upstream end has a smaller diameter than the distal, downstream end; positioning the delivery catheter such that the first stent is at a treatment site within the proximal main vessel with the distal, downstream end adjacent the vascular bifurcation; and deploying the first stent in the proximal main vessel such that the first stent self expands to a configuration in which the proximal, upstream end of the first stent has a smaller diameter than the distal, downstream end of the first stent, and in which the distal, downstream end communicates with both the first and the second distal branch vessels.
