SYSTEMS AND METHODS FOR BARIATRIC THERAPY

摘要

The present invention provides bariatric therapy systems. One system includes a gastrointestinal implant device and a delivery mechanism therefor. The device can include a sleeve for placement into a small intestine and to minimize absorption of nutrients by its walls. An anchoring mechanism coupled to a proximal end of the sleeve and designed to be secured within the stomach can be provided. A passageway extending through the anchoring mechanism and the sleeve can also be provided, along which food can be directed from the stomach to the small intestine. The delivery mechanism can include a housing for accommodating the device, and a deploying balloon situated within the housing and which can be actuated to direct the sleeve of the device from within the housing to the site of implantation. Methods for providing bariatric therapy are also provided by the present invention.
