DEPLOYMENT SYSTEM FOR SOFT STENTS

摘要

A stent delivery system (10) and a method for delivering a stent are provided. The stent delivery system includes an outer sheath (38) having a proximal portion (20), a distal portion (30) and a first lumen (44) extending at least partially through the sheath. The system further includes an inner shaft (40) slidably received within the first lumen and extending at least partially through the sheath. A tubular non-expandable stent (42) is slidably positionable within the first lumen, disposed distal to the inner shaft and operably contacts a pushing surface on the inner shaft. The inner shaft and the stent are slidable relative to the outer sheath, the outer sheath providing sufficient rigidity to the stent for delivery of the stent to a delivery site.
