Rapid exchange stent delivery system and associated components
First Claim
1. A medical device assembly, comprising:
- a first tubular member, the first tubular member having a distal tip, a holding region for holding an expandable medical device thereon, and a first proximal region;
wherein a first opening is defined in the first tubular member adjacent to the holding region, the first opening having a first length;
a second tubular member slidably disposed over the first tubular member, the second tubular member including a distal end, a covering region, and a second proximal region;
wherein a second opening is defined in the second tubular member adjacent to the covering region, the second opening having a second length;
wherein the second tubular member includes a ramp that extends into the first opening; and
wherein the first length is longer than the second length.

Abstract
A rapid exchange stent delivery catheter includes an inner tubular member having a proximal portion, a distal portion, a stent holding portion located adjacent the distal portion of the inner member, and a guide wire lumen extending from a proximal guide wire opening disposed distal of the proximal portion of the inner member to a distal guide wire opening disposed at a distal end of the inner member. The proximal guide wire opening has a first length. An outer tubular member is slidably disposed about the inner member. The outer member has a proximal portion, a distal portion, and a guide wire opening disposed distal of the proximal portion of the outer member. The guide wire opening of the outer member has a second length that is shorter than the first length and a guide wire ramp extends into, and is movable along the first length.
