Claim Text:
1. A prosthesis delivery device comprising: a proximal end and a distal end, a rotatable inner cannula having a cannula lumen, a cannula handle, a prosthesis retention section, a proximal attachment and release mechanism, a distal attachment and release mechanism, and a prosthesis retained on the prosthesis retention section, the prosthesis having a proximal end at least partially disposed over and releasably attached to the proximal attachment and release mechanism and a distal end releasably attached to the distal attachment and release mechanism, wherein the cannula handle is, at the same time, at least partially slidable over the inner cannula and rotatable with the inner cannula, a delivery handle near the distal end of the delivery device, the delivery handle comprising: a positioner disposed at least partially over the cannula and having a positioner handle proximal to the cannula handle, the positioner having a lumen and a proximal end, where the proximal end is releasably attached to the distal end of the prosthesis, and where the positioner handle is releaseably engaged with the cannula handle, and where the cannula handle is rotatable with the cannula relative to at least the positioner; a sheath handle proximal to the positioner handle and attached to a sheath having a sheath lumen, the sheath extending from the sheath handle to at least the proximal attachment and release mechanism, wherein the sheath and sheath handle are distally slideable; and wherein rotation of the inner cannula releases the proximal end of the prosthesis from the delivery device and withdrawal of the sheath from over the proximal end of the positioner shaft releases the distal end of the prosthesis from the positioner proximal end.
