8. A method of performing a circular anastomosis of a substantially tubular body organ, comprising the steps of:
- inserting an operative head slidably coupled to an endoscope into a substantially tubular organ, wherein the operative head includes a stapling mechanism and a tissue receiving space extending around a distal end thereof;
drawing a portion of tissue from the organ into the tissue receiving space, wherein the portion of tissue extends around an entire circumference of the organ;
firing a plurality of staples through the tissue received in the tissue receiving space;
cutting away from the stapled portion of tissue, a portion of tissue to be resected.

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.

21. 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 tissue receiving space formed in a distal end thereof and a stapling mechanism for driving staples radially outward from a longitudinal axis of the operative head through the tissue receiving space around an entire circumference thereof; and
a tissue gripping mechanism for drawing into the tissue receiving space a portion of tissue extending around an entire circumference of the organ.

22. An operative head for an apparatus for performing endoluminal anastomosis of an organ, comprising:
-
an endoscope receiving lumen for slidably receiving a flexible endoscope therein;
a tissue receiving space formed in a distal end thereof;
a stapling mechanism for stapling an entire perimeter of a closed space;
an anvil moveable with respect to the stapling mechanism to vary in size a gap therebetween between a tissue receiving position in which tissue may be drawn is into the gap and a stapling position in which the tissue is gripped between the anvil and stapling mechanism; and
a tissue gripping mechanism for drawing into the tissue receiving space a resection portion of tissue so that, when the resection portion of tissue is drawn into the tissue receiving space, a stapling portion of tissue is positioned between the anvil and the stapling mechanism, wherein the stapling portion of tissue extends around an entire circumference of the organ. - View Dependent Claims (1, 3, 4, 5, 6, 7, 23, 24, 25, 26, 27, 28, 29)

29-1. The operative head according to claim 28, further comprising a second balloon coupled to a source of inflation fluid wherein, when inflated, the second balloon drives the tissue cutting mechanism to sever tissue radially within the closed space.
-
30-2. The operative head according to claim 30, further comprising a second balloon coupled to a source of inflation fluid wherein, when inflated, the second balloon drives the tissue cutting mechanism from the ready position, across the gap between the staple mechanism and the anvil to sever tissue radially within the closed space from the stapled tissue.
