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 disposable about the medical device receiving region and being movable relative to the inner tube; wherein the medical device sheath has an outer surface that is free of any other structure of the medical device delivery system; a medical device sheath retraction device connected to the medical device sheath, the medical device sheath refraction device being a tubular member extending proximally from the medical device sheath; an outer sheath disposed about the inner tube; wherein the inner tube, the outer sheath, and the guidewire lumen have substantially the same longitudinal axis; wherein the outer sheath has an outer surface, a proximal end, a distal end, and a distal region extending proximally from the distal end, wherein the distal region has a constant outer diameter; wherein the outer surface of the outer sheath is free of any structure of the medical device delivery system adjacent the distal end of the outer sheath; wherein the outer sheath is disposed about a portion of the medical device sheath retraction device; wherein the distal end of the outer sheath terminates proximal of the medical device receiving region; wherein the tubular member and the inner tube are not coaxial; and wherein the medical device sheath is movable relative to the outer sheath.
