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.
Claims43
Apparatus for achieving weight loss in a patient comprising:
- an artificial stoma device sized and configured to be installed in an esophagus or stomach of the patient;
- a gastrointestinal sleeve connected to the artificial stoma device, the gastrointestinal sleeve sized and configured to extend from the artificial stoma device through the stomach and into the intestines of the patient,
- a non-tissue cuff on the stoma device to secure the stoma device at an installation site;
- and
- means for reversibly attaching the gastrointestinal sleeve to the artificial stoma device.
Apparatus for achieving weight loss in a patient, comprising:
- an artificial stoma device sized and configured to be installed in a stomach of the patient;
- a gastrointestinal sleeve connected to the artificial stoma device the gastrointestinal sleeve sized and configured to extend from the artificial stoma device through the stomach and into the intestines of the patient;
- and
- means for reversibly attaching the gastrointestinal sleeve to the artificial stoma device.
Apparatus for achieving weight loss in a patient, comprising:
- a tissue attachment cuff comprising a non tissue material, sized and configured to be installed without the need for tissue plication at an attachment site in the vicinity of the gastroesophageal junction in the patient;
- at least one tissue anchor for extending from the attachment cuff completely through the adjacent tissue wall at the attachment site;
- and
- a gastrointestinal sleeve connected to the cuff, the gastrointestinal sleeve sized and configured to extend from the cuff through the stomach and into the intestines of the patient;
- wherein the tissue anchor is moveable from a first configuration in which it is advanceable through a delivery cannula, and a second configuration for functioning as an anchor on the serosal side of the tissue walk the tissue anchor comprising a button shape when in the second configuration.
