Methods for performing gastroplasty
View Patent ↗Methods for performing gastroplasty include reducing the effective volume or cross-sectional area of the stomach via approximation of gastric tissue. Such reduction preferably is achieved endoluminally, either with or without laparoscopic ports. In one variation, a sleeve, pouch, Magenstrasse and Mill, Vertical Banded Gastroplasty (“VBG”), etc.,is formed within the stomach by approximating opposing anterior and posterior segments or ridges of the stomach wall at locations inferior to the gastroesophageal junction. In another variation, opposing walls of the stomach are approximated at a plurality of substantially random locations to reduce an effective volume of the stomach. In yet another variation, both a sleeve and random approximations are formed, the random approximations preferably disposed in a portion of the stomach excluded by the sleeve. In still another variation, opposing walls of the stomach are approximated over significant lengths at random or specified locations.
1. A method for performing gastroplasty, the method comprising:
inserting a securing element down the throat of a patient to a position within the stomach of the patient;
forming tissue folds on opposing walls of a patient's stomach;
approximating the tissue folds;
securing the approximated tissue folds with the securing element; and
reinforcing the approximated and secured tissue folds.
2. The method of claim 1 , wherein approximating the tissue folds further comprises approximating the tissue folds with instruments advanced down the patient's throat.
3. The method of claim 1 , wherein forming tissue folds further comprises forming serosal-to-serosal tissue folds.
4. The method of claim 1 , wherein securing the approximated tissue folds comprises securing the tissue folds with at least one securing element, and wherein approximating the tissue folds further comprises approximating the tissue folds via a ratcheting or tensioning mechanism of the securing element.
5. A method for performing gastroplasty, the method comprising:
endoluminally forming a plurality of tissue folds secured by tissue anchors on opposing walls of a patient's stomach with instruments advanced down the throat of the patient:
endoluminally approximating the opposing walls with instruments advanced down the throat of the patient; and
reinforcing the approximated opposing walls using a plurality of tissue anchors.
