Abstract:
1. A system for performing anastomosis on opposing free ends of a body canal, comprising: a plurality of staples having first and second opposing sides joined together at a junction and defining an included space between the sides, the staples having an open and a closed position; and an annular staple support comprising first and second annular portions, said annular support defining an interior opening, said support holding said plurality of staples about said opening when said staples are in the open position, wherein the annular portions comprise annular ledge portions for surrounding a body canal positioned in the interior opening, the staples in the open position being circumferentially arranged and secured to the staple support such that one side of each staple abuts an adjacent portion of a ledge and the other side of the staple extends laterally outward from the ledge, whereby a first free end of the body canal can be positioned in the included space between the first and second sides when the staples are in the open position, folded back over itself and over the side of the staple adjacent the ledge, and when the staples are moved to the closed position by a staple closing mechanism the free ends of the body canal will be clamped between the opposing sides of the staples and the staples are released from the support.
