Patent number: 7220268Abstract: The present invention relates to new and useful apparatus, systems and methods for providing an effective tool for intraluminally directed vascular anastomosis of a graft vessel to a receiving blood vessel that is performed according to a minimally invasive procedure. The intraluminally directed vascular anastomosis does not require the interruption of blood flow in the receiving blood vessel and it is versatile enough to suitably combine a variety of cutting, welding, soldering, sealing, and joining techniques. The intraluminally directed anvil apparatus comprises an anvil and a wire used for signaling the optimal anastomosis site; this signaling can be performed when the initial exploration is performed. An anastomosis device is used in conjunction with the intraluminally directed anvil apparatus for opening the anastomosis fenestra and joining the anastomosed structures.Type: GrantFiled: November 12, 2003Date of Patent: May 22, 2007Assignee: Integrated Vascular Interventional Technologies, L.C.

Patent number: 6743244Abstract: The present invention is directed to a cutting apparatus for cutting an opening in a vessel for subsequent anastomosis. The cutting apparatus includes an anvil, an anvil pull and a cutter. The anvil is inserted through a small incision at the anastomosis site and brought into contact with the interior wall of a vessel so that the anvil distends the wall of the vessel. The cutter is then urged against the portion of the vessel wall that is distended by the anvil to form an opening in the vessel wall. The anvil has a surface that is softer than the cutter so that the cutter can cut completely through the vessel and depress into the anvil.Type: GrantFiled: October 31, 2001Date of Patent: June 1, 2004Assignee: Integrated Vascular Interventional Technologies, L.C.Inventors: Duane D.

Patent number: 6736825Abstract: A paired, expandable anastomosis device joins two vessels together and can expand and contract with changes in the size of the two vessels. The anastomosis device has two expandable rings with a plurality of holding tabs. The holding tabs of one ring are shaped to enable a graft vessel tissue to be everted through one of the rings and to be held on one of the rings. Similarly, the holding tabs of the other ring are shaped to enable a target vessel to be everted through the other ring and to be retained by the holding tabs. Once the graft and target vessels are loaded, the rings are adapted to be brought together to a position in which the graft and target vessels are anastomosed together.Type: GrantFiled: December 27, 2001Date of Patent: May 18, 2004Assignee: Integrated Vascular Interventional Technologies, L C (IVIT LC)Inventors: Duane D.
