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;
the tissue cutting mechanism formed as a substantially cylindrical element having a cylindrical side wall, a proximal end wall and a sharpened distal rim;
a staple driver ring formed as a substantially cylindrical element, wherein the tissue cutting mechanism is configured to be movable independently of the staple driver ring; and
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.

Abstract
An apparatus for performing endoluminal anastomosis of an organ comprises an operative head including an endoscope receiving lumen for slidably receiving a flexible endoscope therein, the operative head including an annular tissue receiving space extending around a circumference of a distal end thereof and a stapling mechanism for firing staples around an entire circumference of the tissue receiving space and a tissue gripping mechanism for drawing into the tissue receiving space a portion of tissue extending around an entire circumference of the organ.

8. An apparatus for performing endoluminal anastomosis of an organ, comprising:
-
an operative head including an endoscope receiving lumen for slidably receiving a flexible endoscope therein, the operative head including a stapling mechanism and an anvil movable relative to one another to define a tissue receiving space therebetween, the stapling mechanism firing staples around an entire circumference of the tissue receiving space, 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 including; a tissue cutting mechanism formed as a substantially cylindrical element having a cylindrical side wall, a proximal end wall and a sharpened distal rim; a lockout mechanism preventing the tissue cutting mechanism from operating until operation of the tissue stapling mechanism has been completed; a staple driver ring formed as a substantially cylindrical element wherein the tissue cutting mechanism is configured to be movable independently of the staple driver ring; and the tissue gripping mechanism for drawing into the tissue receiving space, a portion of tissue extending around an entire circumference of the organ. - View Dependent Claims (9, 10, 11, 12, 13, 14)
