Method and apparatus for intraluminal prosthesis delivery
First Claim
1. A catheter for use in combination with a balloon catheter for delivering a radially expansible tubular prosthesis having transverse surfaces, said catheter comprising:
- a tubular catheter body having a proximal end, a distal end, and a lumen therebetween, wherein the catheter body is axially split over a distal region thereof to define a radially expansible portion, and wherein the lumen slidably receives the balloon catheter so that a balloon thereon can be aligned within the radially expansible portion of the body; and
a structure comprising abutting surfaces attached to the axially split region of the catheter body which is adapted to engage the transverse surfaces on the tubular prosthesis to inhibit axial movement thereof.

Abstract
A catheter for use in combination with a balloon angioplasty catheter for delivering stents and other intraluminal prostheses comprises a tubular catheter body having a radially expansible portion. The stent is disposed over the radially expansible portion, and structure is provided for retaining the stent on the tubular body prior to deployment. The retaining structure may be active, i.e., requiring the user to retract retaining elements, such as axial members, sheaths, or the like. Alternatively, the retaining structure may be passive, wherein balloon expansion results in release of the prosthesis from the retaining structure. Particular methods for fluoroscopically positioning stents using such delivery catheters, for delivering two or more stents using such delivery catheters, and for overexpanding the ends of the stents for anchoring them in place, are also described.
