Claim:
1. A device for facilitating side-to-side arteriovenous fistula comprising: a first device half having a first proximal end and a first distal end, the first device half having a first inner surface and a first outer surface opposite the first inner surface, the first device half comprising a first anastomosis window formed therethrough, the first anastomosis window defining a first arch and a second arch opposite the first arch, the first device half comprising a first barb ridge extending from the inner surface of the first arch and comprising a plurality of first barbs attached to and extending therefrom, and a second barb ridge extending from the inner surface of the second arch and comprising a plurality of second barbs attached to and extending therefrom; a second device half having a second proximal end and a second distal end, the second device half having a second inner surface and a second outer surface opposite the second inner surface, the second device half comprising a second anastomosis window formed therethrough, the second anastomosis window defining a third arch and a fourth arch opposite the third arch, the second device half comprising a third barb ridge extending from the inner surface of the third arch and comprising a plurality of third barbs attached to and extending therefrom, and a fourth barb ridge extending from the inner surface of the fourth arch and comprising a plurality of fourth barbs attached to and extending therefrom, the third arch being opposite and in alignment with the first arch, the second arch being opposite and in alignment with the fourth arch, the first anastomosis window being in alignment with the second anastomosis window; a proximal wall disposed normal to each of the first device half and the second device half, the proximal wall connecting the first proximal end of the first device half to the second proximal end of the second device half; and a distal wall disposed normal to each of the first distal end of the first device half and the second distal end of the second device half, the distal wall connecting the first distal end of the first device half to the second device half, the distal wall being opposite the proximal wall, the first device half being opposite the second device half and spaced apart therefrom to define an interior space between the first device half and the second device half; each of the barb ridges extending into the interior space, the first barb ridge being opposite and spaced apart from the third barb ridge defining a first vessel capture space between the plurality of first barbs and the plurality of third barbs, the second barb ridge being opposite and spaced apart from the fourth barb ridge defining a second vessel capture space between the plurality of second barbs and the plurality of fourth barbs, the first vessel capture space being opposite and in alignment with the second vessel capture space.
