Abstract
Official abstract text for this publication.
One preferred embodiment includes a stent delivery system including a retractable sheath and an outer stability sheath. The stability sheath freely rotates relative to the retractable sheath, relieving compression forces caused by twisting of stability sheath in when in a tortuous conformation.
First claim
Opening claim text (preview).
What is claimed is: 1. A stent delivery system, comprising: a first tubular member having a distal end sized and shaped to receive a stent and a proximal end stiffer than the distal end; a second tubular member being longitudinally slidable over said first tubular member; a handle body; a strain relief element coupled to a distal end of the handle body; a third tubular member being at least partially disposed over said second tubular member, said third tubular member being longitudinally compressible relative to said first tubular member and to said second tubular member, extending distally of a distal end of the strain relief element, and coupled to the handle body; wherein the handle body is coupled to said second tubular member to retract said second tubular member relative to said first tubular member, and the strain relief element is at least partially disposed over the third tubular member. 2. The stent delivery system of claim 1 wherein the third tubular member comprises a stability sheath distal of the strain relief element. 3. The stent delivery system of claim 1 wherein stability sheath comprises a crumple zone.
