Patent number: 9345502Abstract: Stomach tissue is manipulated to form, for example, a restored flap of a gastroesophageal flap valve. The manipulation includes gripping stomach tissue from within the stomach while the stomach is inflated to promote visualization and stabilization of the gripped stomach tissue. Once the stomach tissue is gripped, the stomach is deflated and pulled into a mold. The molded tissue is then fastened with at least one fastener. The stomach is inflated to a first pressure during visualization and then to a second higher pressure during the stomach tissue gripping.Type: GrantFiled: February 4, 2013Date of Patent: May 24, 2016Assignee: EndoGastric Solutions, Inc.Inventors: Stefan J.
