Attorney, Agent or Firm: Schwartz; Ansel M.

The present invention pertains to an apparatus for implanting a graft into a vessel of a patient. The apparatus includes a mechanical delivery mechanism for delivering the graft to a desired location inside the vessel and then withdrawing from the vessel. The apparatus also has an anchoring mechanism for anchoring the graft to the interior surface of the vessel from the inside of the vessel. The anchoring mechanism is connected to the delivery mechanism. The present invention pertains to a method of implanting a graft in a vessel of a patient. The method includes the steps of delivering a graft to a desired location inside the vessel with a delivery mechanism. Next, there is the step of piercing the vessel from the interior of the vessel with anchors connected to the graft from inside the vessel. Then, there is the step of anchoring the anchors in the vessel to hold the graft in the vessel by changing the shape of the anchors.
