Abstract
A pre-loaded prosthesis delivery device is described. In one example, the prosthesis delivery device is pre-loaded with a single wire that allows the device to be tracked into place within a vessel and also facilitates cannulation of a branch vessel. The delivery device further comprises a prosthesis that is releasably coupled to a delivery catheter by using two attachment wires to secure the proximal end of the prosthesis to the delivery device in a tri-fold configuration.
Claims20
A prosthesis delivery device comprising:
- a delivery catheter having a proximal end,
- a tubular prosthesis releasably coupled to the proximal end of the delivery catheter, wherein the prosthesis has a proximal end, a distal end, a lumen extending between the proximal end and distal end, a sidewall of graft material, an inner graft surface, an outer graft surface, and a fenestration formed in the sidewall of the prosthesis,
- wherein the delivery catheter extends proximally through at least a portion of the prosthesis lumen and through the fenestration to a location external of the prosthesis and adjacent a first point on the outer graft surface of the graft at the proximal end,
- a first proximal attachment mechanism releasably coupling a second point on the proximal end of the prosthesis to the delivery catheter, wherein the second point is circumferentially spaced from the first point;
- a second proximal attachment mechanism releasably coupling a third point on the proximal end of the prosthesis to the delivery catheter, wherein the third point is circumferentially spaced from the first point in one direction and from the second point in the opposite direction;
- wherein the first and second proximal attachment mechanisms draw the second and third points to the first point to form three folds of graft fabric;
- wherein the folds extend about the delivery catheter in a folded configuration such that the outer surface of the graft at least partially wraps around the delivery catheter.
