A method of implanting a prosthesis in a patient at a treatment site includes advancing an outer catheter of a prosthesis delivery system in the patient distal to the treatment site. An inner sheath and a curved guidewire lumen of the delivery system are advanced from the outer catheter to the treatment site along a guidewire while the outer catheter remains stationary relative to the patient. Advancing the inner sheath causes rotation of the prosthesis to thereby rotationally align the prosthesis at the treatment site. The inner sheath is retracted to deploy a prosthesis from within the inner sheath and at the treatment site. The delivery system is then retracted from the patient. |
