SWELLABLE POLYMERIC DEVICE FOR DIETARY REGULATION

摘要

A stomach implant is provided to reduce the volume of the stomach for treating obesity and for dietary regulation. The implant is made from a hydrogel capable of reducing its volume when exposed to stomach acids. Volume reduction assures free passage of digested foods through the stomach and into duodenum without the implant obstructing any of the stomach openings. In embodiments, the implant is made of a hydrogel and can be dehydrated to minimize its volume prior to insertion.
