1. A method of attaching a tubular graft to a vessel wall, comprising the steps of:
- positioning a tubular graft within a vessel;
positioning a tissue anchor deployment catheter at a first position within the graft, the deployment catheter comprising a first plurality of tubular anchor supports, each carrying a tissue anchor; and
advancing the anchors out of the tubular supports and into the vessel wall to secure the graft to the vessel wall.

8. A method of attaching a first tubular structure to a second tubular structure in a patient, comprising the steps of:
-
identifying a first tubular structure in the patient;
positioning a second tubular structure in communication with the first tubular structure;
positioning an anchor deployment catheter within at least one of the first and second tubular structures; and
deploying a plurality of tissue anchors from the catheter and through at least one of the first and second tubular structures, to attach the first tubular structure to the second tubular structure;
wherein the deploying step comprises advancing an introducer along an anchor support to deploy an anchor from the anchor support. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
