Abstract
A delivery system and kit for endovascularly delivering a prosthesis along a guidewire to an curved implantation site includes a control handle having a handle body with a prosthesis movement control assembly movably disposed thereto. A proximal end of a catheter is connected to the control handle. A prosthesis delivery assembly is movably disposed in the catheter. The delivery assembly has a guidewire lumen slidably receiving therein the guidewire and having a curved distal end orienting the delivery assembly when passing through a curved vessel portion. A method for automatic endovascular alignment of the prosthesis includes loading it in the distal delivery assembly, positioning the guidewire into the curved implantation site, and threading the guidewire lumen over the guidewire with the delivery assembly and into the implantation site to at least approximately align the curved distal portion to a curve of the curved implantation site and, thereby, orient the prosthesis.
