Stent delivery system
First Claim
1. A stent delivery system comprising:
- an inflation shaft defining an inflation lumen, the inflation shaft having a proximal end and a distal end;
an expandable balloon having a proximal end and a distal end, the balloon defines a balloon lumen, the proximal end of the balloon being sealingly affixed to the distal end of the inflation shaft;
a tubular sheath having a proximal end and a distal end, the tubular sheath defining a tubular sheath lumen, the inflation shaft extending longitudinally through the tubular sheath lumen;
an expandable sheath having a proximal end and a distal end, the proximal end of the expandable sheath being affixed to the distal end of the tubular sheath, the expandable sheath defining an expandable sheath lumen, the balloon extending longitudinally through the expandable sheath lumen; and
an expandable stent, the stent having a proximal end and a distal end, the stent being coaxially mounted upon the expandable sheath.

Abstract
What is disclosed is a stent delivery system comprising an inflation shaft having an expandable balloon sealingly mounted at the distal end thereof and a tubular sheath having the inflation shaft longitudinally running therethrough. The tubular sheath has an expandable sheath at the distal end thereof with the balloon longitudinally running therethrough and an expandable stent mounted on the expandable sheath. Also disclosed is a method of delivering a stent into a body lumen. The method comprises the steps of providing an inflation shaft having an expandable balloon sealingly mounted at the distal end thereof and providing a tubular sheath having the inflation shaft longitudinally running therethrough. The expandable sheath has the balloon longitudinally and slidingly running therethrough, and an expandable stent is mounted on the expandable sheath. The stent is positioned in the body lumen at the treatment site and the balloon is inflated simultaneously with the expandable sheath to deploy the stent.
