Abstract
Apparatus for delivering an endoluminal stent or prosthesis in the vasculature of a body. The apparatus has an introducer adapted for insertion into the vasculature having a diameter and a first portion of lock fitting on its distal end. It also has a cartridge exterior the body having inner tubular member with a diameter equal to or less than the diameter of the introducer which contains the endoluminal stent or prosthesis in its entirety in a compressed state, an outer sheath, and a second portion of the lock fitting. The apparatus also includes a pusher adapted to fit within the inner tubular member of the cartridge and engage a distal end of the endoluminal or prosthesis. The first portion of the locking fitting on the introducer mates with the second portion of the lock fitting on the cartridge to prevent relative movement of the introducer in the cartridge. The inner tubular member and the introducer form a continuous lumen upon attachment of the cartridge and the introducer. The lumen extends from exterior of the body to a point of implantation in the vasculature, through which the endoluminal stent or prosthesis is pushed by said pusher.
