Abstract:
1. A system for endoluminally performing an anastomosis of a substantially tubular organ, the system comprising: a flexible endoscope; an operative head slidably mountable on the endoscope, the operative head including a stapling mechanism and an anvil moveable relative to one another to define a tissue receiving space therebetween and a tissue cutting mechanism extending into the tissue receiving space proximal of the stapling mechanism, the stapling mechanism and the anvil being coupled to one another so that all components thereof remain within a lumen of the organ at all times during the anastomosis, the operative head further comprising: a tissue gripping mechanism for drawing tissue from the organ into the tissue receiving space, wherein the portion of tissue drawn into the tissue receiving space extends around a complete circumference of the organ; wherein, operation of the stapling mechanism drives staples through a portion of tissue received within the tissue receiving space around the entire circumference thereof and, operation of the tissue cutting mechanism severs from the tissue through which the staples were driven a portion of tissue located within the tissue receiving space separated proximally therefrom.
