Claims20
A medical device, comprising:
- an inner tubular member having a first region with a first outer diameter and a second region distal of the first region with a second outer diameter that is smaller than the first outer diameter;
- a floating bumper disposed along the second region of the inner tubular member, the floating bumper having an inner diameter that is smaller than the first outer diameter and that is larger than the second outer diameter;
- an expandable implant disposed along the inner tubular member and disposed distally of the floating bumper;
- and
- a sheath disposed over the inner tubular member.

A self-expanding stent delivery system, comprising:
- an inner tubular member having a first region with a first outer diameter and a second region distal of the first region with a second outer diameter that is smaller than the first outer diameter;
- a floating bumper disposed along the second region of the inner tubular member, the floating bumper having an inner diameter that is smaller than the first outer diameter and that is larger than the second outer diameter;
- a self-expanding stent disposed along the inner tubular member and disposed distally of the floating bumper;
- a sheath disposed over the inner tubular member;
- and
- wherein the sheath is capable of shifting between a delivery configuration where the sheath extends over the self-expanding stent and a deployment configuration where the sheath is disposed proximally of the self-expanding stent.

A self-expanding stent delivery system, comprising:
- an inner tubular member having a first region with a first outer diameter and a second region distal of the first region with a second outer diameter that is smaller than the first outer diameter;
- a floating bumper disposed along the second region of the inner tubular member, the floating bumper having an inner diameter that is smaller than the first outer diameter and that is larger than the second outer diameter;
- a self-expanding stent disposed along the inner tubular member and disposed distally of the floating bumper;
- a deployment sheath slidably disposed along the inner tubular member;
- wherein the deployment sheath is capable of shifting between a delivery configuration where the deployment sheath extends over the self-expanding stent and a deployment configuration where the deployment sheath is disposed proximally of the self-expanding stent;
- wherein the deployment sheath have a first section having a first inner diameter and a second section having a second inner diameter greater than the first inner diameter;
- and
- wherein the second section of the deployment sheath is disposed adjacent to the second region of the inner tubular member.
