US 7,703,459 B2 · Apparatus and methods for mapping out endoluminal gastrointestinal surgery

Abstract

Apparatus and methods are provided for mapping out endoluminal gastrointestinal surgery, including endoluminal gastric reduction. Mapping is achieved by locally marking the interior of the gastrointestinal lumen at specified locations. In some variations, mucosectomy and/or mucosal ablation are performed to map out endoluminal GI surgery, to facilitate direct endoluminal engagement of underlying muscularis tissue and/or to initiate a wound healing response. Specialized apparatus may be provided to achieve desired spacing and/or positioning of tissue markings, as well as to actually form the markings. Methods of using apparatus of the present invention are provided.

Dependent claims

A method for directly engaging muscularis tissue from an interior of a patient's stomach, the method comprising:

removing plugs of mucosal tissue from opposing anterior and posterior segments of the interior of the patient's stomach to expose underlying muscularis tissue;
engaging the exposed underlying muscularis tissue along the opposing anterior and posterior segments;
and
forming opposing tissue folds along the opposing engaged segments of muscularis tissue.
