Methods and devices for intragastric support of functional or prosthetic gastrointestinal devices
First Claim
1. An intragastric support system comprising:
- a proximal orientation element having a proximal end and a distal end, wherein the proximal orientation element has a diameter sized to fit within the lumen of an esophagus;
wherein the long axis of the proximal orientation element is configured to be substantially parallel with the long axis of the esophagus; and
a distal support element configured to reside non-circumferentially against only a portion of the stomach cavity;
wherein the distal support element is transformable from a first configuration where a long axis of the distal support element is configured to be substantially parallel with the long axis of the proximal orientation element during delivery to a second configuration where the long axis of the distal support element is configured to be not substantially parallel with the long axis of the proximal orientation element when implanted in the body, wherein the support system is configured such that the proximal end of the proximal orientation element is in the esophagus and the distal end of the proximal orientation element is in the stomach when implanted in the body;
wherein the proximal orientation element further comprises a food-collecting ring.

Abstract
Disclosed herein are systems and methods for attaching or maintaining the position of a therapeutic or diagnostic device in a body lumen, such as the GI tract without necessarily requiring any penetrating attachments through any body walls. The system can include at least two elements: a proximal orientation element and a distal support element. The proximal orientation element can be configured to reside at least partially within the esophageal lumen and the distal support element can be configured to reside in the stomach, such as along the greater curve of the stomach. An intragastric support system can have a first configuration in which the long axis of the proximal orientation element is substantially parallel and/or substantially coaxial with the long axis of the distal support element, and a second configuration in which the long axis of the proximal orientation element is not substantially coaxial with the long axis of the distal support element. The second configuration can thus advantageously retain the intragastric support system in place and prevent unwanted proximal migration of the distal support element into the esophagus or distal migration into the intestine.

17. A method for treating a patient, comprising:
-
providing an intragastric support system, the system comprising a proximal orientation element having a proximal end and a distal end, a distal support element, and a food collecting ring; inserting the proximal orientation element and the distal support element into a gastrointestinal tract lumen, wherein a long axis of the proximal orientation element is substantially parallel to a long axis of the distal support element; positioning the system such that the proximal end of the proximal orientation element is within the esophagus of a patient and the distal support element is within the stomach of a patient; and transforming the distal support element such that the long axis of the distal support element is not substantially parallel to the long axis of the proximal orientation element, wherein after the transforming step the distal support element resides non-circumferentially along less than the entirety of the wall of the stomach. - View Dependent Claims (18, 19, 20)
