Abstract
A prosthesis delivery comprising a rotatable inner cannula and a prosthesis releasably coupled to a proximal end of the inner cannula is disclosed. The inner cannula has a first position in which the prosthesis is retained on the cannula and a second position in which the prosthesis is released. At least one magnet is disposed on the inner cannula. A handle assembly is disposed about a distal portion of the inner cannula, the handle assembly comprising a rotary collar having at least one magnet disposed on the inner surface thereof, wherein the at least one magnet disposed on the rotatable inner cannula and the at least one magnet disposed on the inner surface of the rotary collar comprise a magnetic attraction. The magnetic attraction translates torque from rotation of the rotary collar to rotate the inner cannula from the first position to the second position to thereby release the prosthesis.
