The preferred apparatus includes a ring-like body through which a first living vessel end is extended and everted back over and a second living vessel end which is drawn over the everted first living vessel end to place the lumen of these vessels in apposition. A plurality of fasteners are employed to clinch the vessel ends in sealed apposition at the ring-like body. These preferred fasteners are staple-like and have one leg located inside of the ring-like body but exterior of the first living vessel, and a second leg located exterior of the margin of the second living vessel at the ring-like body. The ring-like body may also be provided with at least one needle-like projection which may be adapted to either permanently impale and hold the vessel ends at the ring-like body or temporarily impale and hold the vessel ends until the fastener are employed. In accordance with the method for employing the apparatuses of the present invention, there is provided a surgeon's tool for holding and controlling the ring-like body and a surgeon's tool for impaling and manipulating the vessel ends to bring them simultaneously into position at the ring-like body. Additionally, a surgeon's tool is provided for closing fasteners in accordance with the present invention. The surgeon's tool is employed to shut the staple-like fasteners to clinch the vessel ends in a sealed apposition at the ring-like body.
