ABSTRACT:
A member, preferably in the form of a ring, is provided to simplify anastomosing severed ends of blood vessels and insuring patency of the anastomized blood vessels. The member has an interior surface significantly larger than the outside diameter of the blood vessel and means at least three spaced-apart locations for tethering blood vessel-connecting sutures thereto.
The ring is disposed around one of the severed ends of the blood vessel, the ends of the blood vessel are connected with at least three sutures at spaced apart locations and the sutures are tethered to the ring to apply outward radial stress to the connected blood vessels, which radial stress in several directions helps to assure patency of the anastomosed blood vessel.
