Patent ID: 7491224

Claim:
A stent delivery system comprising: a guide wire; a delivery catheter having an inner tubular member with a proximal end and a distal end and a guide wire lumen extending from the proximal end to the distal end for receiving the guide wire, the tubular member including a region for mounting a compressed stent thereon with a tip assembly attached to the mounting region including a tip component having a tapered shape which facilitates the insertion and delivery of the delivery catheter in a patient's body vessel and an outer tubular member having a restraining sheath overlying a portion of said inner tubular member to maintain the stent in a compressed position, the outer tubular member and restraining sheath being adapted for axial movement with respect to said inner tubular member, the tip component being made from a polymeric material compounded with a radiopaque substance and a wire coil molded into the polymeric material; and a housing assembly having a pull-back handle slidably mounted on a base, the inner tubular member having a proximal end attached to the base and the outer tubular member having a proximal end attached to the pull-back handle, wherein movement of the pull-back handle proximally retracts the restraining sheath proximally from the compressed stent on the inner tubular member while the inner tubular member remains stationary.
