Abstract
According to the present invention, an anastomosis catheter with internally mounted cam pieces holding a plurality of curved needles adjacent apertures in the side of the catheter is provided. The curved needles are attached to lengths of suture material which are installed to run along the outer surface of the central cam pieces to their distal end, where they reverse back along the inner core of the catheter. When the central cam pieces are withdrawn, and moved proximally, the cam surface forces the curved needles out the associated apertures. As the catheter is deployed in a hollow organ, such as a human urethra, the curved needles, as they are deployed, grasp the end of the urethra, which then can be held in position for suturing to the bladder. The other end of the suture materials could have straight needles attached to them to facilitate attaching the urethra to the bladder.
