AbstractA stent delivery system and method. A stent is routed to a desired position within a vessel within a subject. A delivery wire is routed out an opening in a delivery catheter and looped over a portion of the stent and then routed back inside the delivery catheter. At an extreme distal end of the stent, the wire again exits the delivery catheter, reengages the stent and is pushed back into the catheter center passageway. This compresses the stent into a form whereby the delivery catheter can be maneuvered through a vessel to position the stent. To release the stent from the delivery catheter, the delivery wire is retracted so that its distal end passes out both pair of openings in the delivery catheter allowing the stent to expand into engagement with the vessel wall.
