Vascular everting instrument

The invention concerns a means having two instruments for everting an end of a severed artery over a ferrule surrounding the artery. A handle of a flaring instrument is squeezed to rotate a head section. Arms mounted to the head section open in the manner of an iris-diaphragm mechanism to flare the arterial end. Another instrument, curved forceps, urge the artery via the ferrule into the head section such that the arterial end is everted over the ferrule. Two everted arterial ends may be joined by sutureless vascular anastomosis.
