Blood perfusion device

A perfusion device and a delivery system for repair of a damaged portion of a body vessel. Perfusion device can include a tubular body that is self-expandable, having a proximal portion, a distal portion, and an intermediate portion. One or more series of barbs can be disposed circumferentially along the intermediate portion. Barbs are capable of penetrating into the tunica intima and tunica media of said vessel wall upon insertion of said device into said body vessel, and not into said tunica adventitia. A graft can be associated with the tubular body. Graft has a proximal end and a distal end, and preferably extends entirely along a luminal wall of the tubular body. Graft may also extend along an exterior surface of the tubular body at the proximal and distal portions. Delivery devices for the perfusion implant and methods of delivering the perfusion implant are also provided.
