Abstract

Methods of treatment using a gastrointestinal implant device removably anchored within an animal's gastrointestinal tract. For example, the implant device includes a collapsible anchor for anchoring the device coupled to a proximal end of a flexible sleeve. The implant device can be anchored within the stomach, within the pyloric orifice, and/or distal to the pylorus and extended into the duodenum. All partially-digested food, or chyme, exiting the stomach is funneled through the device. Methods of treatment include treating obesity by one or more of: limiting the absorption of nutrients within the duodenum; delaying the mixing of chyme with digestive enzymes; alter hormonal triggers; and providing negative feedback. Alternatively or in addition, the desired result includes treating a diseases, such as diabetes, or temporarily shielding a portion of the intestine to promote healing within the intestine.

Claims19

Dependent claims

A method of treating obesity, diabetes or a gastrointestinal condition comprising the steps of:

with a delivery system, delivering an implant within the digestive system, the implant having a collapsible sleeve anchor coupled to a proximal portion of a floppy, flexible sleeve, open at both ends, the sleeve defining a lumen between the two ends and made of a thin and conformable material so that it collapses in the intestine;
positioning the floppy sleeve within the intestine with an extension of the delivery system extending beyond the anchor;
securing the sleeve anchor within the digestive system while the flexible sleeve is unsupported at the distal end;
and
withdrawing the extension of the delivery system from the digestive system through the lumen of the floppy sleeve, leaving the floppy sleeve in the digestive system.
