Abstract
A stent delivery system for delivering a self-expanding stent to a predetermined location in a vessel includes a catheter body having an axial guidewire lumen and a pull-wire lumen. A medical device such as a self-expanding stent is held in a reduced delivery configuration for insertion and transport through a body lumen to a predetermined site for deployment. The stent is carried axially around the catheter body near its distal end and held in its reduced configuration by a retractable outer sheath. A proximal retraction handle is connected to the proximal end of the catheter body and includes a pistol grip trigger engaging a rachet mechanism, which is connected to a pull-wire which extends through the pull-wire lumen and is connected to the retractable outer sheath.
