Sutureless anastomosis systems

An anastomotic graft and fitting system comprising:

• a fitting having a tubular portion with a first radius, a proximal end and a flared distal end, the flared distal end having an edge defining at least one additional radius larger than the first radius, the edge additionally defining at least one aperture extending into the flared distal end, and wherein at least one section of tubing is disposed along at least a portion of the edge, the tubing defining a lumen;
• a wire at least partially disposed through the lumen;
• and
• a tubular graft affixed to the fitting.

A method for creating an anastomosis comprising:

• creating a puncture in a vessel wall;
• disposing a fitting near said puncture, said fitting having a tubular portion with a first radius and a proximal end, the fitting having a flared distal end defining an edge, the edge defining at least one additional radius larger than the first radius, the edge additionally defining at least one aperture extending into the flared distal end;
• rotating the fitting such that the aperture captures the vessel wall as the edge is introduced into the puncture and through the vessel wall;
• and
• continuing to rotate the fitting until the entire flared distal end passes through the puncture and the vessel wall such that when the rotation is complete the flared distal end is disposed inside a vessel lumen defined by said vessel wall and the tubular portion is disposed outside the vessel lumen.
