Stress-resistant children: The search for protective factors

An anastomotic apparatus including an outer tubular member connected with a source of vacuum pressure for holding the open end of a donor blood vessel in contact with the side wall of a recipient vessel, thereby permitting adhesive joining of the vessels. To test the anastomosis seal, a source of positive pressure is provided for pressurization of the interior of the outer tubular member. The anastomotic apparatus also includes an inner tubular member concentrically mounted within the outer tubular member having a cutting head secured to the lower end thereof which may be advanced to remove that portion of the recipient vessel circumscribed by the sealed end of the donor vessel. In one embodiment, the cutting head includes a plurality of cutter blades attached to and extending axially from the lower end of the inner tubular member. In a second embodiment, the cutting head includes an electrical resistance heating wire for cutting the recipient blood vessel by cauterization.
