Abstract
A device for disposing a radially self-expanding endoprosthesis in a body lumen. The implantation device includes an elongated catheter having a distal end and an outer surface over which the endoprosthesis is placed a sheath disposed to releasably surround at least a portion of the endoprosthesis, holding the endoprosthesis on the catheter in a radially contracted state, and a flexible elongation release element cooperating with the sheath. The sheath is released, permitting the surrounded portion of the endoprosthesis to expand, by axial withdrawal of the release element.
