Gastrointestinal sleeve device and methods for treatment of morbid obesity
First Claim
Patent Images
1. A method of treating a patient, comprising the steps of:
- providing an artificial stoma device;
transesophageally advancing the device to an attachment site in the vicinity of the gastroesophageal junction; and
attaching the device at the attachment site;
wherein the attaching step comprises advancing at least one anchor through a delivery cannula and through the wall of the stomach, the wall having a mucosal surface and a serosal surface, and positioning the anchor against the serosal surface; and
wherein the anchor is enlargeable from a first configuration for passing through the cannula, to a second configuration for functioning as an anchor.

Abstract
Apparatus and methods are described for treatment of morbid obesity using minimally invasive techniques. The apparatus includes a system of components that may be used separately or in combination for effectively reducing stomach volume, bypassing a portion of the stomach and/or small intestines, reducing nutrient absorption in the stomach and/or small intestines and/or depositing minimally or undigested food farther than normal into the intestines, thereby stimulating intestinal responses. The components described include an artificial stoma device, a gastric sleeve device, an intestinal sleeve device and a combined gastrointestinal sleeve device.

6. A method of treating a patient, comprising the steps of:
-
providing an elongate tubular sleeve having a proximal end and a distal end; transesophageally advancing the sleeve to an attachment site in the vicinity of the gastroesophageal junction; positioning the distal end of the sleeve in the intestine; and attaching the proximal end of the sleeve at the attachment site; wherein the attaching step comprises advancing at least one anchor through the wall of the stomach, the wall having a mucosal surface and a serosal surface, and positioning the anchor against the serosal surface. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
