ABSTRACT:
A delivery catheter and gripping system for enabling manipulation of a prosthesis deployed or implanted at a repair site in a corporeal lumen, for repositioning of the prosthesis. The delivery catheter includes a grip at the proximal end, a jacket enlarged portion at the distal end, and a shaft therebetween, and has a channel extending therethrough, for enabling insertion, removal, expansion and compression of the gripping system. The gripping system is housed in the delivery catheter, and includes a grip and biasing spring at the proximal end, a plurality of resilient gripping elements at the distal end, and a deploying wire therebetween for enabling gripping, maneuvering, and repositioning of the prosthesis to the desired location. The catheter jacket is retracted from enclosing the gripping elements, enabling the gripping elements to expand about the prosthesis end, and is then advanced to compress the gripping elements into engagement with the prosthesis end for maneuvering thereof so as to reposition the prosthesis.
