Duodenal gastrointestinal devices and related treatment methods

Abstract

An intragastric device includes an elongated member having a proximal end and a distal end and an anchor connected to the elongated member. The anchor includes a stem, a first arch and a second arch, and a curvilinear element. The stem includes a proximal end and a distal end. The distal end of the stem is attached to the proximal end of the elongated member. Each arch has first and second ends and a proximal peak therebetween. The first end of each arch is attached to the proximal end of the stem, and the second end of each arch extends radially away from the stem. The curvilinear element connects the second end of the first arch to the second end of the second arch.

AI Technical Summary

Benefits of technology

The patent describes an intragastric device that can be used to treat medical conditions. The device includes an elongated member and an anchor that is connected to the elongated member. The anchor has a stem, first and second arches, and a curvilinear element. The elongated member can be a single piece of wire or formed from a single piece of wire. The device can also include flow reduction elements and / or bioactive materials. The anchor can be locked together or have a fastener to hold it in place. The device can be used to treat medical conditions such as obesity or gastrointestinal motility disorders.

Problems solved by technology

While weight loss can improve many of the medical complications associated with obesity, its management as a health concern has proven troublesome.

A variety of approaches including dietary methods, psychotherapy, behavior modification, and pharmacotherapy have each met with some success but as a whole failed to effectively control the rapid growth in the incidence and severity of obesity seen in the United States.

These stomach reduction surgeries had limited early success, but now it is known that the stomach can stretch back to a larger volume over time, limiting the achievement of sustained weight loss in many individuals.

While these described surgical procedures can be effective to induce a reduction in food intake and / or overall weight loss in some, the surgical procedures are highly invasive and cause undue pain and discomfort.

Further, the described procedures may result in numerous life-threatening postoperative complications.

These surgical procedures are also expensive, difficult to reverse, and place a large burden on the national health care system.

This approach has yet to be convincingly shown to be successful, and a number of problems are associated with the gastric balloon device, however, including poor patient tolerance and complications due to rupture and / or migration of the balloon.

Other non-surgical devices designed to induce weight loss limit the absorption of nutrients in the small intestine by funneling food from the stomach into a tube found within the small intestine so that the food is not fully digested or absorbed within the small intestine.
