Method and device for full-thickness resectioning of an organ
First Claim
1. A full-thickness resection system for removing a full-thickness portion of a body organ, the system comprising:
- a flexible endoscope;
a stapling mechanism, wherein the endoscope is slidably received through at least a portion of the stapling mechanism, the stapling mechanism comprising;
an anvil;
a stapling head coupled to the anvil so that the anvil and the stapling head are moveable with respect to one another between a tissue receiving position and a stapling position, wherein a gap formed between the stapling head and the anvil is larger in the tissue receiving position than it is in the stapling position;
a position adjusting mechanism for moving at least one of the anvil and the stapling head relative to the other of the anvil and the stapling head between the tissue receiving and stapling positions;
a staple firing mechanism for sequentially firing, when a plurality of staples are received in the stapling head and the stapling head and the anvil are in the stapling position, the plurality of staples in groups of at least one from the stapling head across the gap against the anvil and through any tissue received in the gap;
a knife for cutting a portion of tissue received within the gap; and
a control unit which remains outside the body, the control unit being coupled to the stapling mechanism for controlling operation of the position adjusting mechanism and the staple firing mechanism.

Abstract
A full-thickness resection system comprises a flexible endoscope and a stapling mechanism, wherein the endoscope is slidably received through at least a portion of the stapling mechanism. The stapling mechanism comprises an anvil and a stapling head mounted to the anvil so that the anvil and the stapling head are moveable with respect to one another between a tissue receiving position and a stapling position and wherein a gap formed between the stapling head and the anvil is larger in the tissue receiving position than it is in the stapling position. A position adjusting mechanism is provided for moving the anvil and the stapling head between the tissue receiving and stapling positions and a staple firing mechanism sequentially fires a plurality of staples from the stapling head across the gap against the anvil and through any tissue received in the gap and a knife cuts a portion of tissue received within the gap. A control unit which remains outside the body is coupled to the stapling mechanism for controlling operation of the position adjusting mechanism and the staple firing mechanism.

20. A method of performing a full-thickness resection of tissue within a substantially tubular body organ comprising the steps of:
-
inserting a stapling mechanism slidably coupled to an endoscope into a tubular body organ via a body orifice, wherein the stapling mechanism includes a stapling head and an anvil coupled to one another for movement between a stapling position and a tissue receiving position, wherein a gap formed between the stapling head and the anvil is smaller in the stapling position than in the tissue receiving position;
moving the stapling mechanism into the tissue receiving position;
drawing a portion of the wall tissue of the body organ to be resectioned into the gap;
moving the stapling mechanism into the stapling position;
firing a plurality of staples through the tissue received in the gap, wherein the portion of wall tissue into which the staples are fired extends around a longitudinal axis of the body organ by an angle of less than 360°
; and
cutting away from the wall of the body organ the portion of tissue to be resectioned. - View Dependent Claims (21, 22, 23, 24)
