Patent ID: 8628562

Claim:
A stent delivery system, comprising: an inner member having a proximal region, a distal region, and a stent receiving region at a distal end of the inner member for receiving a stent thereabout; a stent sheath having a proximal end, the stent sheath being disposed about the stent receiving region, the stent sheath being movable relative to the inner member; a stent sheath retraction device extending proximally from the stent sheath to a proximal end of the stent delivery system, wherein the stent sheath retraction device is a hypotube or a pull back wire; an outer sheath disposed about the inner member, the outer sheath having a proximal end and a distal end, the distal end of the outer sheath terminating proximal of the stent receiving region, the stent sheath being movable relative to the outer sheath; wherein the outer sheath is disposed about a portion of the stent sheath retraction device; wherein the distal end of outer sheath is separated from the proximal end of the stent sheath by at least a length of a stent when the stent sheath is in an extended position; and wherein the stent sheath retraction device and the inner member are the only structures extending between the proximal end of the stent sheath and the distal end of the outer sheath.
