Abstract
A stent, a system for delivering a stent and a method of assembling a stent on a stent delivery shaft. The stent delivery system comprises a delivery shaft and a stent configured to be positioned about the delivery shaft. The stent includes an extension extending circumferentially from a portion of the stent to a free end, thereby defining a shoulder surface. A belt has a first portion fixed relative to the delivery shaft and a second portion positioned circumferentially about at least a portion of the stent to retain the stent in an at least partially constrained configuration. A release wire is configured to releasably engage at least a portion of the belt to retain the belt. The shoulder surface engages at least a portion of the belt to minimize axial movement of the belt during release of the release wire from engagement with the belt.
