Abstract
The present invention provides a self-expanding stent delivery system comprising a catheter, a self-expanding stent having a plurality of interconnected expansion cells therein and concentrically arranged around the catheter near the distal end of the catheter, a retractable sheath for covering the stent constructed and arranged for retraction to release the stent to self-expand, and a stent holder abutting the stent for holding the stent in place until the retractable sheath is fully retracted. During retraction of the retractable cover, the stent holder prevents the stent from substantially moving longitudinally until the retractable sheath has been completely removed from the stent.
