Devices and methods for endoluminal plication
First 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 extending parallel to at least one of the first and second jaws and 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 while the parallel orientation of the tissue acquisition member and at least one of the first and second jaws is maintained.

Abstract
Devices and methods are provided for forming and securing a tissue plication. 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.

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. - View Dependent Claims (11, 12, 13, 14, 15)

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 the tissue acquisition member and a longitudinal axis of any of a first and a second jaw of the stapling member are 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 the longitudinal axis of the tissue acquisition member that is substantially parallel to the 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. - View Dependent Claims (17, 18, 19)
