Abstract:
1. A method of connecting a donor vessel to a recipient vessel of a body comprising: employing a ring structure comprising a ring portion and at least two protruding pointed structures extending from the ring portion to attach said donor vessel to said recipient vessel wherein the donor vessel has a wall comprising an inner and an outer surface and an open end, with at least two incisions in the wall wherein the incisions are substantially evenly spaced around the circumference of the donor vessel, beginning at the open end of the donor vessel, and extending in an axial direction towards the ring structure and terminating at or before the ring structure to create at least two tail structures and an orifice reinforced by said ring structure; attaching the ring structure at said inner and/or outer surface of the donor vessel at a position proximate of said open end, establishing a contact between said donor vessel and said recipient vessel via said orifice; wherein said the recipient vessel, upon engagement with said ring structure via said protruding pointed structures, is stretched between about 10% and about 20% at least between at least two of said protruding pointed structures, forming a contact plane between the inner surface of said donor vessel at said tail structure and said wall of said recipient vessel; and attaching the donor vessel to the recipient vessel via said contact plane.
