Abstract
A gastric reduction pouch of a stomach is formed by gathering stomach tissue circumferentially from within the stomach to form a reduced diameter stomach section. A plurality of fasteners are deployed within the gathered stomach tissue to maintain the reduced diameter stomach portion. The gathering step may include folding the stomach tissue to produce a plurality of stomach tissue folds. A device is disclosed that is particularly adapted to permit such gastric reduction of a previously formed gastric reduction pouch.
Claims22
An apparatus comprising:
- an elongated member having a through lumen and a distal end for transoral placement in the stomach, the lumen being dimensioned to permit an endoscope to be passed there through;
- and
- a valve at the distal end of the elongated member and communicating with the lumen, the valve being configured to permit the endoscope to pass there through into the stomach, to seal the lumen from the stomach when the endoscope is passed there through into the stomach and to seal the lumen from the stomach when the endoscope is retracted from the valve.
A device for forming and maintaining tissue folds from within the stomach comprising:
- an elongated member having a distal end for transoral placement in the stomach;
- a tissue gatherer carried on the distal end of the elongated member for placement into the stomach, the tissue gatherer defining a tissue chamber including an opening to permit tissue to be pulled into the tissue chamber under vacuum to form a tissue fold within the tissue chamber, the tissue chamber having a cross-sectional dimension, the cross-sectional dimension being greater proximal from the opening than distal from the opening;
- and
- a fastener deployer that directs a fastener into the tissue chamber and through the folded tissue for binding the tissue fold.
A method of reducing a gastric reduction pouch of a stomach in size, comprising:
- gathering stomach tissue from within the stomach to form a stomach tissue fold;
- deploying at least one fastener within the gathered stomach tissue to maintain the stomach tissue fold;
- and
- repeating the gathering and deploying steps until a gastric reduction pouch of a desired size is formed.
