Abstract
An assembly for delivering a self-expanding stent to an intraluminal location comprising a sheath having a generally non-compliant first portion and a compliant second portion, with the stent positioned within the generally non-compliant first portion for stent delivery. Upon stent deployment, the stent passes from the generally non-compliant first portion into the compliant second portion, and then out of the sheath. The compliant second portion permits the stent to at least partially expand before it passes out of the sheath, so that the force with which the stent expands once outside the sheath is tempered.
Claims6
A stent delivery assembly, comprising:
- a tubular sheath having a longitudinal axis, said tubular sheath having a first portion with a first compliance and a second portion with a second compliance, wherein the second compliance is greater than the first compliance, and wherein the second portion includes a terminal end that is tubular and that is continuous about its circumference;
- and
- a self-expanding stent disposed within the first portion of the generally tubular sheath.
