Stent delivery system
First Claim
1. A catheter system comprising:
- a catheter comprising an expandable distal portion, the expandable distal portion having an outer diameter, a first end and a second end, constructed and arranged for expanding the outer diameter of said expandable distal portion from a contacted state to an expanded state; and
a first stent retaining member in the region of said distal portion of said catheter positioned around said catheter, the first stent retaining member having a length, a first end fixed in place to said catheter and a second end terminating and lying over said first end of said expandable distal portion, the first stent retaining member comprising a first portion and a second portion, wherein the first portion of the first stent retaining member comprises a first material and the second portion of the first stent retaining member comprises an elastomeric material, the first material being harder than the elastomeric material and the first material being bound to the elastomeric material.

Abstract
A stent delivery system to facilitate introduction and placement of a stent, including a catheter having an expandable distal portion constructed and arranged for expanding the outer diameter of the catheter from a contracted state to an expanded state: a stent positioned around the distal portion of the catheter having a contracted condition and being expandable to an expanded condition, and being sized in the contracted condition to closely surround the catheter in the contracted state, the expandable distal portion of the catheter including a balloon within which there is included on the catheter shaft at least one body of a diameter larger than the catheter shaft to which the stent and balloon are fitted, as by crimping, for holding the stent in place until it is released therefrom by expansion of the balloon.
