Patent ID: 8236041

Claim:
A deployment system for treating a bifurcation of a main vessel and first and second branch vessels, comprising: an elongate, flexible body, having a proximal end and a distal end; a single stent carried by the distal end of the body, the single stent comprising a proximal, upstream end, and a distal, downstream end, and a stent wall extending therebetween; a releasable restraint, for retaining the stent on the flexible body, the releasable restraint comprising an axially moveable outer sheath having a lubricious layer, wherein a distal end of the lubricious layer is spaced proximally from the outer sheath's distal end, thereby providing a section of the releasable restraint at the outer sheath's distal end region that is free of the lubricious layer; and a distal tip comprising an annular recess formed therein configured to receive the releasable restraint's distal end, wherein the annular recess at least partially overlaps the lubricious layer; wherein the distal, downstream end of the stent is larger in diameter than the proximal, upstream end of the stent in an unconstrained expanded configuration, and wherein the stent wall defines a single central lumen and is radially symmetrically disposed about the longitudinal axis of the flexible body when retained on the body.
