Abstract
Stomach tissue is manipulated and fastened with a tissue grasper and a tissue shaper to form folds in the stomach. The tissue grasper and the tissue shaper rotate and translate relative to one another. The tissue grasper has a plurality of vacuum orifices to adhere the tissue grasper to tissue.
Claims11
A method of forming stomach tissue at an intersection of the stomach and the esophagus adjacent the lesser curvature, comprising the steps of:
- providing a device having a tissue shaper;
- introducing the tissue shaper into an esophageal tract in a first position;
- maintaining the tissue shaper in the first position while inducing a curvature about one or more elongate elements, wherein:
- each elongate element is coupled to at least one coil-shaped tissue displacing element, and wherein:
- each coil-shaped tissue displacing element is coupled with only one elongate element;
- maintaining the tissue shaper in the first position while engaging stomach tissue with three coil-shaped tissue displacing elements;
- displacing the stomach tissue into the tissue shaper after the introducing, inducing, and engaging steps while the tissue shaper remains in the first position;
- individually displacing the three coil-shaped tissue displacing elements until a threshold tension is reached and then applying a lock to lock the three coil-shaped tissue displacing elements;
- applying a plurality of fasteners through the stomach tissue moved into the first tissue shaper with the three coil-shaped tissue displacing elements;
- the applying step is carried out to form a fold having a convex surface, the convex surface facing inward relative to the esophagus;
- and
- releasing the stomach tissue after the applying step so that the stomach tissue positioned in the tissue shaper falls back into the stomach.
