Abstract:
1. A medical device delivery system for delivering a medical device into a body lumen comprising: an inner tube defining a guidewire lumen, the inner tube having a proximal region and a distal region and a medical device receiving region at the distal end of the inner tube for receiving a medical device thereabout; a medical device sheath having a proximal end and a distal end, the medical device sheath being disposed about the medical device receiving region and being movable relative to the inner tube from about the medical device receiving region proximally to a position along the inner tube which is proximal to the medical device receiving region; a medical device sheath retraction device, the medical device sheath retraction device, having an outer diameter, being a tubular member and extending proximally from the medical device sheath, wherein the tubular member and the medical device sheath are directly attached to one another; and an outer sheath disposed about the inner tube, the inner tube, the outer sheath, and the guidewire lumen having the substantially same longitudinal axis and the outer sheath having an inner diameter, a proximal end and a distal end, wherein no portion of the medical device delivery system is disposed about the distal end of the outer sheath and wherein the outer sheath is disposable about a portion of the medical device sheath retraction device, the distal end of the outer sheath terminating proximal of the medical device receiving region, wherein the medical device sheath is movable relative to the outer sheath and wherein the outer diameter of the medical device sheath is greater than the inner diameter of the outer sheath.
