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.

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 h...
