First Claim
Patent Images
1. A deployment system for treating a bifurcation of a main vessel and a first and second branch vessels, comprising:
- an elongate, flexible body, having an end and a downstream end;
a first stent carried by the downstream end of the body;
a drug, releasably carried by the stent;
a releasable restraint, for retaining the stent on the flexible body;
wherein the downstream end of the stent is larger in diameter than the upstream end of the stent in an unconstrained expanded configuration.

Abstract
A device and method for treating pathological narrowing of fluid-carrying conduits of the human body (such as blood vessels) in an area of a bifurcation is disclosed. In particular, a stent delivery system configured to carry one or more of a pair of dissimilar stents. At least one of the stents is particularly suited for treating a widened portion of a blood vessel immediately proximal to a bifurcation. The stent delivery system can also include a handpiece adapted to selectively deliver the stents.
