摘要：
A prosthesis delivery device comprises a cannula having an expandable positioning device disposed at the proximal end thereof. A prosthesis is retained on the cannula distal of the expandable device. Expansion of the expandable device retains and centers the delivery device and the prosthesis carried thereon in the vessel and allows repositioning of the prosthesis without contacting the proximal end of the prosthesis with the vessel walls prior to deployment.
