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.

Claims1

Dependent claims

A delivery system for delivering a medical device to a predetermined location in a body lumen, the delivery system comprising:

a catheter body having proximal and distal ends for transporting a medical device to a predetermined site in a body lumen for deployment;
a medical device having proximal and distal ends carried by the catheter body near the distal end, and
a retractable outer sheath having proximal and distal ends and surrounding the medical device and maintaining the medical device in a delivery configuration where the medical device has a reduced radius along its entire axial length, wherein the proximal end of the retractable outer sheath is tapered to form a smooth atraumatic transition between the retractable outer sheath and the catheter body which aids in extraction of the delivery system from a body lumen, the proximal end of the retractable outer sheath comprising a thermally molded extrusion swaged in place with a marker band.

Dependencies are inferred from the claim text.
