Rapid exchange stent delivery system and associated components
First Claim
1. A rapid-exchange catheter, comprising:
- an inner tubular member, having a proximal end, a distal end, and a guide wire lumen extending from a proximal guide wire opening disposed distal of the proximal end at the inner tubular member to a distal guide wire opening disposed at the distal end of the inner tubular member;
an guide wire sleeve disposed about at least a portion of the inner tubular member, having a proximal end, a distal end, and a guide wire opening disposed within the guide wire sleeve the guide wire opening distal of the proximal end of the guide wire sleeve, wherein the guide wire opening within the guide wire sleeve further comprises a guide wire ramp extending into the proximal guide wire opening of the inner tubular member.

Abstract
A rapid exchange stent delivery catheter which includes an inner tubular member and an outer tubular member slidably disposed thereon. The inner tubular member and the outer tubular member have rapid exchange type guide wire openings. The guide wire opening of the outer tubular member is preferably shorter in length than the guide wire opening of the inner tubular member to protect the inner workings of the catheter. The outer tubular member may include a guide wire access sleeve having a guide wire ramp extending into the guide wire lumen of the inner tubular member. The guide wire sleeve may be a separate component from the remainder of the outer tubular member to facilitate efficient manufacture.
