Abstract

A radical prostatectomy anastomosis device including a cartridge having a plurality of anchors slidably disposed in a plurality of distally angled radial channels formed in the cartridge and a pusher assembly operatively coupled within the cartridge. The pusher assembly being configured and adapted to push each of the plurality of anchors out of the angled radial channels of the radial cartridge. The device further including a fitting removably coupled to a distal end of the cartridge. The fitting including a flange having a plurality of holes formed radially around the flange, wherein each of the plurality of holes includes suture locking means configured and adapted to permit a suture to be drawn distally through each of the plurality of holes and to prevent the sutures from being drawn proximally through each of the plurality of holes. The device further including a plurality of sutures secured to an inner surface of the cartridge. The sutures passing through the fitting, through a respective hole of the plurality of holes formed in the fitting and secured to an outer surface of a respective anchor.

Claims

1-28. -28. (canceled)

29. An anastomosis device, comprising:

a cartridge having a body with a plurality of longitudinal channels open on the body;

an anchor fitting for engaging a body vessel including a flange with a plurality of holes, each hole having a suture lock, the anchor fitting being removably coupled to a distal end of said cartridge and having an expandable anchor; and

a plurality of sutures, each suture being secured to a respective needle anchor and extending through at least one of the holes in said flange of said anchor fitting, and proximally through the body.

30. The anastomosis device of claim 29, wherein the anchor fitting includes an annular sleeve and the sutures extend proximally through said annular sleeve of said anchor fitting.

31. The anastomosis device of claim 29, wherein said anchor fitting further comprises a body and an enlarged distal end;

a plurality of longitudinal channels for receiving said needle anchors.

32. The anastomosis device of claim 29, further comprising a pusher assembly slidably disposed within said cartridge, said pusher assembly being arranged to engage each needle anchor and to deploy said plurality of needle anchors out of said cartridge by moving said pusher assembly distally within said cartridge

33. The anastomosis device of claim 32, wherein said longitudinal channels include distally angled channels formed in said enlarged distal end for receiving said needle anchors therein.

34. The anastomosis device of claim 32, wherein said pusher assembly further comprises a hub slidably received on said body and a plurality of drive wires wherein each of said drive wires is configured and adapted to be received in a respective one of said longitudinal channels of said body.

35. The anastomosis device of claim 34, wherein said cartridge further comprises a compression spring disposed about a central shaft and said drive wires and between said hub of said pusher assembly and a proximal surface of said body.

36. The anastomosis device of claim 35, wherein said cartridge further comprises a cover configured and adapted to enclose said central shaft and said pusher assembly therein, said cover including a proximal head.

37. The anastomosis device of claim 29, wherein said flange of said anchor fitting includes a plurality of anchoring members formed on a proximal surface thereof.

38. The anastomosis device of claim 29, wherein said suture lock is configured and adapted to permit said sutures to be drawn distally through said holes formed in said flange and to prevent said sutures from being withdrawn proximally through said holes.
