The hollow member has a first clamping surface along an edge of the window, while the closure member has a second clamping surface opposing the first clamping surface and disposable substantially adjacent thereto in a clamping or closure configuration of the instrument. The instrument additionally comprises a tissue occlusion component mounted to at least one of the hollow member and the closure member for acting on tissues gripped between the first clamping surface and the second clamping surface, to couple the tissues to each other. ## Claims ### Claim 1 A system for endoscopic surgery within a body lumen of a patient comprising a body member having a distal portion expandable from a collapsed insertion configuration to an expanded configuration to provide an expanded chamber having an expanded region therewithin having an increased transverse dimension proximal of a distalmost end of the body member, the chamber having an opening to receive tissue into the chamber and the chamber expandable asymmetrically, an elongated working channel in the body member dimensioned to receive a working instrument therethrough such that a working head of the instrument is angled laterally into within the expanded region of the chamber and positionable within the chamber to access the tissue received within the chamber, the elongated working channel having a first opening into the chamber to enable the working head of the working instrument to access the chamber and a second channel dimensioned to receive a visualization device to visualize tissue within the chamber, the first channel positioned radially of the received visualization device in the second channel such that the working instrument received in the first channel is movable independently of the visualization device received in the second channel, the second channel having a second opening into the chamber separate from the first opening to access the chamber for visualization separate from insertion of the working instrument. ### Claim 2 (depends on 1) The system of claim 1, wherein the chamber is expandable to only one side of an axis of the body member. ### Claim 3 (depends on 2) The system of claim 2, further comprising a stiffening rod movable with respect to the chamber. ### Claim 4 (depends on 3) The system of claim 3, wherein the stiffening rod is movable parallel to a longitudinal axis of the body member. ### Claim 5 (depends on 1) The system of claim 1, further comprising a visualization device, wherein a distal end of the visualization device is positionable at an angle to be directed laterally toward the chamber. ### Claim 6 (depends on 5) The system of claim 5, wherein the visualization device is an endoscope with a distal end bendable with respect to an axis, the end bendable laterally within the chamber. ### Claim 7 (depends on 5) The system of claim 5, wherein the chamber is located laterally with respect to the second channel. ### Claim 8 (depends on 1) The system of claim 1, further comprising an elongated member extending through the body member to expand the chamber. ### Claim 9 (depends on 1) The system of claim 1, wherein the chamber is located laterally with respect to a longitudinal axis passing through the second channel. ### Claim 10 (depends on 1) The system of claim 1, wherein the chamber includes a deformable sheath. ### Claim 11 (depends on 1) The system of claim 1, wherein the chamber is separated from the working channel. ### Claim 12 (depends on 11) The system of claim 11, further comprising an elongated member to form the expanded chamber. ### Claim 13 (depends on 1) The system of claim 1, wherein the body member is dimensioned and configured for insertion into the colon for treating a polyp. ### Claim 14 (depends on 1) The system of claim 1, wherein the chamber is dimensioned to receive a polyp therein. ### Claim 15 A system for endoscopic surgery within a body lumen of a patient comprising a body member having a distal portion expandable from a collapsed insertion configuration to an expanded configuration to provide an expanded chamber having an expanded region therewithin having an increased transverse dimension, the chamber having an opening to receive tissue into the chamber, an elongated working channel in the body member dimensioned to receive a working instrument therethrough such that a working head of the instrument is angled laterally within the expanded region of into the chamber and positionable within the chamber to access the tissue received within the chamber, and a second channel dimensioned to receive a visualization device to visualize tissue within the chamber and a movable stiffening rod within a third channel of the body member, the third channel radially spaced from the visualization device received in the second channel and radially spaced from the working instrument received in the first channel, and the chamber positioned laterally of the stiffening rod, the stiffening rod assisting formation of the chamber and movable from a position proximal of the expanded chamber. ### Claim 16 (depends on 15) The system of claim 15, wherein the chamber is located laterally with respect to a longitudinal axis passing through the second channel. ### Claim 17 (depends on 15) The system of claim 15, wherein the chamber includes a deformable sheath. ### Claim 18 (depends on 15) The system of claim 15, wherein the stiffening rod is movable parallel to a longitudinal axis of the body member. ### Claim 19 (depends on 15) The system of claim 15, wherein the body member has a distalmost end and the chamber is positioned proximal of the distalmost end. ### Claim 20 (depends on 15) The system of claim 15, wherein the chamber is expandable in a region spaced from a distalmost end of the system so a distalmost end of the system is not expanded such that a transverse dimension of the expandable chamber is greater than a transverse dimension of the distalmost end of the system.
