Dispositivos e métodos de emprego de stent

摘要

A stent system comprising a stent body. At least one barb extends from the stent body and is configured such that a free end thereof is biased to extend radially outward from the stent body. A retaining mechanism is positioned to engage the at least one barb when the stent body is in a compressed state and retain the at least one barb in a tucked position relative to the stent body. 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. The shoulder surface engages at least a portion of a belt to minimize axial movement of the belt during release of the release wire from engagement with the belt.
