More particularly, the devices and methods of the present invention can be used to create tissue folds on an anterior and posterior wall of a stomach cavity to reduce the volume thereof. In one aspect, a tissue acquisition and fixation system is disclosed that includes an elongate shaft, an end effector coupled to the elongate shaft and having first and second jaws, and a tissue acquisition member coupled to the end effector by a linkage assembly. At least a portion of the linkage assembly and tissue acquisition member are slidably movable in a direction parallel to a longitudinal axis of the jaws. Further, the tissue acquisition member is vertically movable relative to the end effector such that a distance between a longitudinal axis of the tissue acquisition member and the jaws can be adjusted. ## Claims ### Claim 1 A tissue acquisition and fixation system, comprising: an elongate shaft having proximal and distal ends; an end effector coupled to the distal end of the elongate shaft and having first and second jaws, the first and second jaws having an open position configured to receive tissue therebetween, and a closed position in which the first and second jaws are effective to engage tissue positioned therebetween; a tissue acquisition member coupled to the end effector by a linkage assembly, at least a portion of at least one of the tissue acquisition member and the linkage assembly being slidably movable along a longitudinal axis extending parallel to a longitudinal axis of at least one of the first and second jaws, and the tissue acquisition member being vertically movable relative to the end effector such that a distance between a longitudinal axis of the tissue acquisition member and a longitudinal axis of at least one of the first and second jaws can be adjusted. ### Claim 2 (depends on 1) The system of claim 1, wherein the first and second jaws are further configured to drive at least one fastener through tissue positioned therebetween in the closed position. ### Claim 3 (depends on 1) The system of claim 1, further comprising a lead screw effective to slidably move at least a portion of the tissue acquisition member along a longitudinal axis extending substantially parallel to a longitudinal axis of at least one of the first and second jaws. ### Claim 4 (depends on 3) The system of claim 3, wherein the lead screw is actuated by rotation of a cable extending through the elongate shaft. ### Claim 5 (depends on 4) The system of claim 4, wherein at least a portion of the tissue acquisition member is configured to move vertically relative to the end effector in response to longitudinal translation of the cable. ### Claim 6 (depends on 1) The system of claim 1, wherein the end effector includes a lead screw effective to slidably move at least a portion of the tissue acquisition member and the linkage assembly along a longitudinal axis extending substantially parallel to a longitudinal axis of at least one of the first and second jaws. ### Claim 7 (depends on 1) The system of claim 1, wherein the linkage assembly includes a gear rack and the end effector includes a pinion gear effective to slidably move the linkage assembly and tissue acquisition member along a longitudinal axis extending parallel to a longitudinal axis of at least one of the first and second jaws. ### Claim 8 (depends on 1) The system of claim 1, wherein the end effector includes a hinge pin and the linkage assembly includes a hinge base having a plurality of indexed grooves configured to seat the hinge pin. ### Claim 9 (depends on 8) The system of claim 8, further comprising a cable connected to the linkage assembly and configured to slidably move the hinge base relative to the hinge pin to seat the hinge pin in any one of the plurality of indexed grooves. ### Claim 10 A tissue acquisition and fixation device, comprising: an elongate shaft having a longitudinal axis; an end effector coupled to a distal end of the elongate shaft, the end effector having a fixed jaw and a movable jaw that pivots relative to the fixed jaw; and a tissue acquisition member coupled to the end effector, the tissue acquisition member being limited to: (1) movement along a longitudinal axis of the tissue acquisition member, and (2) movement perpendicular to a first plane extending through the first and second jaws. ### Claim 11 (depends on 10) The device of claim 10, further comprising a lead screw coupled to the tissue acquisition member to allow at least a portion of the tissue acquisition member to translate along the longitudinal axis of the tissue acquisition member. ### Claim 12 (depends on 11) The device of claim 11, wherein the lead screw is driven by rotation of a cable extending through the elongate shaft. ### Claim 13 (depends on 10) The device of claim 10, further comprising a hinge assembly connecting the tissue acquisition member to the end effector. ### Claim 14 (depends on 13) The device of claim 13, further comprising a lead screw coupled to the hinge assembly to allow at least a portion of the hinge assembly and the tissue acquisition member to translate along a longitudinal axis of the tissue acquisition member. ### Claim 15 (depends on 10) The device of claim 10, further comprising a rack gear coupled to the tissue acquisition member and a pinion gear coupled to the end effector to allow the tissue acquisition member to translate along a longitudinal axis of the tissue acquisition member. ### Claim 16 A method of acquiring and fixating tissue using a plurality of fasteners, comprising: positioning a surgical device having a stapling member and a tissue acquisition member adjacent to tissue such that a longitudinal axis of any of a first and a second jaw of the stapling member is parallel to a surface of tissue; drawing tissue to the tissue acquisition member and moving the tissue acquisition member vertically away from the first and second jaws; moving the first and second jaws of the stapling member to a closed position and driving at least one fastener through the tissue disposed between the first and second jaws; moving the first and second jaws of the stapling member to the open position and translating the tissue acquisition member along a longitudinal axis of the tissue acquisition member that is substantially parallel to a longitudinal axis of at least one of the first and second jaws; and moving the first and second jaws of the stapling member to the closed position such that at least one fastener is driven through the tissue disposed between the first and second jaws. ### Claim 17 (depends on 16) The method of claim 16, wherein translating the tissue acquisition member comprises rotating a cable to drive a lead screw coupled to the tissue acquisition member. ### Claim 18 (depends on 16) The method of claim 16, wherein the tissue acquisition member comprises a rack gear connected to a pinion gear on the stapling member, and wherein translating the tissue acquisition member comprises actuating a cable to drive the pinion gear. ### Claim 19 (depends on 16) The method of claim 16, further comprising moving the tissue acquisition member any of vertically away from the first and second jaws of the stapling member and longitudinally with respect to the first and second jaws to further draw tissue through the first and second jaws.
