Abstract

An improved implantable medical device and junction between a blood conduit and a blood vessel are disclosed. The device of the present invention provides a connection to a blood vessel that is resistant to occlusion. Resistance to occlusion is achieved by providing an implantable medical junction with: improved and consistent anastomotic geometry and hemodynamics to minimize turbulence and inappropriate shear stresses on the native blood vessels; intraluminal configuration that does not require penetration through to the luminal surface of the blood vessel or the device for anchoring; protection of the native blood vessel from the forces of blood flow in the impact zone and beyond the impact zone; and isolation of injured and traumatized tissues from the lumen of the blood vessel and the device. A cuff is also provided at the junction to reduce blood leakage from the native blood vessel, and to provide additional device anchoring.
