Method and apparatus for radical prostatectomy anastomosis including an anchor for engaging a body vessel and deployable sutures
First Claim
1. 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;
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; and
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, said pusher assembly further comprising;
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, said cartridge further comprising;
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; and
a cover configured and adapted to enclose said central shaft and said pusher assembly therein, said cover including a proximal head.

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.
