Abstract
A vessel approximator for use in anastomosis has a pair of opposed arms, each adapted to fit within the end of a vessel segment to be anastomosed. The tips of the arms are tapered to assist in placing an end of a vessel segment onto the arm. A stem extends from the junction of the arms to form a T shape. The stem is substantially thinner than the arms to permit the ends of the vessel segments placed over the arms to be proximate to each other to be sutured together. A ring on the end of the stem allows the device to be sutered in place in the surgical field. A notch at the junction of the arms opposite the stem permits the arms to collapse together when the device is removed from the vessel segments by pulling on the stem.
