Bariatric device and method for weight loss

摘要

A bariatric device for use in inducing weight loss, comprising a cardiac element, a pyloric element, and a connecting element between the two other elements, wherein the connecting element provides structure between the cardiac and pyloric elements, keeping them largely in place and at least intermittently touching and applying pressure to the stomach's cardiac, adjacent fundic and pyloric regions, respectively, which produces a satiety signal to the user, giving the recipient a feeling of fullness and reducing his or her hunger feelings. Alternatively, the cardiac and pyloric elements may be symmetrical, so that the device can orient itself either way in the stomach and still achieve the weight loss function.

主权项

1. A bariatric device for placement into a stomach to achieve weight loss, comprising:
a. a first element shaped and sized to contact at least one-third of a circumference of a cardia of the stomach, the first element formed as a first curved shell having a convex side constructed to contact and face the cardia and having a concave side, opposite the convex side, facing and open to the interior of the stomach, and wherein the first shell has a first restriction element formed therein that restricts fluid flow through the first shell from the convex side to the concave side of the first shell, wherein on the concave side the first restriction element is in direct fluid communication with the interior of the stomach; b. a second element formed as a second curved shell having a convex side constructed to contact a pyloric region of the stomach and having a concave side opposite the convex side facing and open to the interior of the stomach and the concave side of the first shell, and wherein the second element has a second restriction element formed therein that restricts fluid flow through the second shell from the concave side to the convex side; and c. a connecting element coupling the first element and the second element, such that the first or the second element maintains at least intermittent contact with the cardia and the second element maintains at least intermittent contact with the pyloric region of the stomach, wherein:
the connecting element includes a plurality of connecting members each extending from the first element to the second element,the plurality of connecting members includes at least a first connecting member and a second connecting member, andthe first connecting member is constructed to extend along the lesser curve of the stomach and the second connecting member is constructed to extend along the greater curve of the stomach.
