Medical connector device

A device for connecting a biological structure, the device comprising a tubular member that includes:

• a longitudinal axis, a radial axis at least substantially perpendicular to the longitudinal axis and a tubular body configured for reversible radial enlargement of the tubular member;
• a distal opening at a distal end of the tubular member;
• a proximal opening at a proximal end of the tubular member;
• the tubular member including an inner surface and a lumen defining a cavity for receiving and retaining a biological structure;
• and a plurality of spaced apart protrusions protruding out from the exterior surface of the body of the device for fixing to the device an end of the biological structure everted over the proximal extremity of the device and for fixing an end of a second structure to the external surface of the device to facilitate contact between the end of the second structure and the everted end of the biological structure for connecting the biological structure to the second structure.
