Device and method for performing endoluminal proximal anastomosis

A method for performing a minimally invasive endoluminal proximal CABG (Coronary Artery Bypass Graft) anastomosis on an aorta using an anastomosis connector clip, the method comprising:

• performing a thoracotomy on at least one side of the body to define a thoracic port;
• identifying an anastomosis graft site on an external surface of the aorta;
• defining a femoral artery port, such that an endoluminal side of said graft site is accessed through said femoral artery port and an external surface of said graft site is accessed through said thoracic port;
• disposing an isolating ring stabilizer over the aorta through said thoracic port;
• stabilizing said graft site with said isolating ring stabilizer disposed over the external surface of said graft site to provide a stabilized graft site;
• puncturing said stabilized graft site to provide a graft site port and a graft site channel through which a guidewire is threaded;
• advancing said guidewire through the vasculature to said femoral artery port, said advancing said guidewire comprising retrieving said guidewire at said femoral artery port and threading said anastomosis connector clip on said guidewire;
• deploying said anastomosis connector clip from the endoluminal side through to the external surface of said graft site channel by said guidewire;
• supporting said anastomosis connector clip in said graft site channel from the external surface of said graft site;
• coupling a connector clip external support member to said anastomosis connector clip over said graft site channel;
• disposing a graft vessel over said anastomosis connector clip on said graft site external surface;
• and
• coupling said graft vessel and said connector clip external support member to said connector clip.
