END-SIDE ANASTOMOSIS SYSTEMS

摘要

End-side anastomosis fittings are described herein. The fittings may be deployed over a guidewire, in a sheath or by applying side-to-side force and feeding the fitting through an opening in a host vessel wall. When a fitting as described is deployed within a host vessel, the exterior surface of the leading petal contacts the interior surface of the host vessel. A deflectable rear petal anchors the fitting within the host vessel once it is advanced through the host vessel wall. Additional petals that may be included provide more complete contact. Support devices usable with the fittings secure a fitting to a host vessel and prevent blood leakage between the opening through the host vessel wall and the base of the end-side fitting. The support device selected may include funnel features designed to relieve stress on a graft attached to the fitting.
