Abstract
A method for automatic endovascular alignment of a prosthesis includes loading the prosthesis in a distal delivery assembly, positioning a guidewire into a curved implantation site, and threading a guidewire lumen over the guidewire with the delivery assembly and into an implantation site to at least approximately align the curved distal portion to a curve of a curved implantation site and, thereby aligning the prosthesis.
Claims38
A method for automatic endovascular alignment of a prosthesis in a curved implantation site of a vessel, which comprises:
- providing a prosthesis delivery system with a longitudinally movable distal delivery assembly and a longitudinally movable guidewire lumen having a curved distal portion;
- loading the prosthesis in the distal delivery assembly;
- positioning a guidewire at least into the curved implantation site of the vessel;
- threading the guidewire lumen over the guidewire along with the loaded distal delivery assembly to advance the guidewire lumen and the loaded distal delivery assembly along the guidewire towards the curved implantation site;
- and
- further advancing the guidewire lumen with the curved distal portion and the loaded distal delivery assembly along the guidewire and into the curved implantation site to at least approximately align the curved distal portion to a curve of the curved implantation site and, thereby, orient the prosthesis.

35-75. (canceled)
A method for automatic endovascular alignment of a prosthesis, loaded in a delivery assembly, in a curved implantation site of a vessel having positioned therein a guidewire extending at least into the implantation site, which comprises:
- providing a prosthesis delivery system with a longitudinally movable guidewire lumen having a curved distal portion;
- threading the guidewire lumen over the guidewire along with the loaded distal delivery assembly to advance the guidewire lumen and the loaded distal delivery assembly towards the implementation site;
- and
- advancing the curved distal portion and the loaded distal delivery assembly into the curved implantation site to at least approximately align the curved distal portion to a curve of the curved implantation site and, thereby, orient the prosthesis.
