Abstract
Abstract Devices, kits and methods for non-suture end-to-end and end-to-side anastomosis of tubular tissue members employ tubular connection members having clip retaining elements comprising annular grooves or flanges in the connection members; and spring clips which comprise a ring-shaped body with separable opposed ends whereby a circular opening defined by the body can be enlarged; the opposed ends have handling elements to facilitate handling of the clips and separation of the opposed ends; specially developed instruments facilitate use of the devices and the anastomosis procedure can be completed much more rapidly than with conventional techniques and has the significant advantage of intima to intima contact at the site of anastomosis with no foreign material exposed to the lumen of the vessels being joined.

Claim 3
Dependent Claim
156 words
A device according to claim 1, wherein said support members (610,612) are substantially annular and said first and second orifices (614,616) are circular, said first and second orifice walls being circular, said means integral with said first and second support members comprising a plurality of outwardly extending spaced apart teeth (618,620), the teeth (618) on said first support member (610) being adapted to engage an end of said first tubular member (685) passed through said first orifice (614) and everted thereover, the teeth (620) on said second support member (612) being adapted to engage an end of said second tubular member (692) passed through said second orifice (616) and everted thereover, whereby in said first positon an annulus (652a) of tissue material at said everted end of said first tubular member (685) is held against anastomatic separation in engagement with an annulus (650a) of tissue material at said everted end of said second tubular member (692).
