Gastro-intestinal compression device

摘要

Devices, methods, and systems for treating Type-2 Diabetes and/or obesity by facilitating the delivery of under-digested nutrients within the gastro-intestinal tract without substantial tissue removal are disclosed. In one aspect, the gastro-intestinal tract of a patient is modified by a gastro-intestinal treatment device comprising an elongate element configured to extend within the gastro-intestinal tract, a first attachment element and a second attachment element disposed on the elongate element, wherein the first attachment element and the second attachment element are configured to attach to the gastro-intestinal tract such that a portion of the gastro-intestinal tract is compressed between the first and the second attachment elements. The length of the gastro-intestinal tract modified by the device is effectively shortened, and its surface area is reduced.

主权项

1. A gastro-intestinal treatment device, comprising:
an elongate element configured to extend within the gastro-intestinal tract; a first attachment element disposed on a first end of the elongate element configured to attach to the gastro-intestinal tract at a first position; and a second attachment element disposed on the distal a second end of the elongate element configured to attach to the gastro-intestinal tract at a second position; wherein the second attachment element is configured to cause at least a portion of the gastro-intestinal tract at the second position to be refracted towards the first position such that a region of the gastro-intestinal tract is compressed between the first and the second attachment elements and the effective length of the region of the gastro-intestinal tract is reduced; wherein at least one of the first attachment element or the second attachment element comprises at least one self-expanding anchoring mechanism comprising a self-expanding ring with one or more protrusions, wherein the protrusions of the self-expanding ring are configured to prevent the first or the second attachment elements from migrating from the position of attachment and wherein the device is configured to maintain the compression of the portion of the gastro-intestinal tract between the first and the second attachment elements.
