STENT DELIVERY SYSTEM AND METHOD

摘要

A system is provided to effectively position a stent within a vessel. The system includes a delivery catheter and a core wire extend through the catheter. The core wire includes an engaging surface region and a capture member disposed thereon, which cooperate to engage a stent such that the stent is able to be advanced or retracted with the advancement or retraction of the core wire. The engaging surface region and the capture member can generally be configured to engage the stent when a portion of the stent is disposed within the lumen of the catheter, and release the stent when no portion of the stent is within the lumen.
