Rapid exchange folded balloon catheter and stent delivery system
First Claim
1. A balloon catheter system comprising:
- an initially deflated inflatable balloon;
a guidewire; and
a stent structure disposed on said balloon and forming an annulus around said balloon, said guidewire padding axially along said balloon inside the annulus formed by said stent structure but outside said balloon.

Abstract
The balloon portion of a balloon catheter for implanting a stent structure is at least initially retained laterally to a guide wire by passing the guide wire axially along the balloon inside the stent structure but not through the interior of the balloon or any permanent guide wire lumen at the location of the balloon. The initially deflated balloon may be folded laterally into a plurality of folds, and the guide wire may pass between the folds or outside the folds as desired. Guide wire lumens may be provided distally and/or proximally of the balloon. An elastic sleeve may be provided around the balloon to help keep the balloon folded prior to inflation and to help refold the balloon during and after deflation. If an elastic sleeve is provided, the guide wire may pass along the balloon inside the sleeve.

39. A balloon catheter system and guide wire system comprising:
-
an initially deflated inflatable balloon; a guide wire passing axially along said balloon without traversing the interior of said balloon; and an annular stent structure disposed around said balloon and said guide wire at the location of said balloon for keeping said balloon adjacent to said guide wire at the location of the balloon. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72)

73. A stent delivery catheter system comprising:
-
an annular stent structure; a balloon having an interior, proximal and distal ends, and an initially deflated configuration wherein the balloon is laterally folded in on itself in a plurality of folds, the annular stent structure retaining the balloon in the initially deflated configuration; a guidewire; a proximal lumen communicating with the interior of the balloon; and a guidewire lumen having a distal end disposed proximally of the proximal end of the balloon member, the guidewire disposed for translation through the guidewire lumen so as to exit the distal end of the guidewire lumen and pass between the plurality of folds of the balloon. - View Dependent Claims (74, 75)
