Embodiment Construction

[0362] In one embodiment, the present specification is directed to an intragastric device for dynamic weight in obese patients to induce weight loss. In various embodiments, the intragastric device comprises a porous three-dimensional structure having a pre-deployment shape and a post-deployment shape. In one embodiment, the porous three-dimensional structure is a non-expanded wire mesh structure, or a helical structure made of a shape memory metal or shape memory polymer obtained from a compressed The shape of the cylinder changes to spherical, elliptical, kidney bean or any predetermined shape of significant volume upon deployment. In another embodiment, the intragastric device is made of a plastic material or polymer such as polyetheretherketone (PEEK) or polyester or a bioresorbable material. The device changes back and forth from the pre-deployment to the post-deployment shape by a temperature change and / or minimal mechanical force as the temperature rises from the room ...

Abstract

A gastrointestinal device for treating obesity includes a three-dimensional porous structure configurable between a compressed pre-deployment configuration to facilitate delivery and an expanded post-deployment configuration. The porous structure includes a first opening at its proximal end and a larger second opening at its distal end. The porous structure also includes a sleeve coupled to its distal end. Optionally, the device further includes a suture at the proximal end of the wire mesh structure to facilitate retrieval and an anti-migration component positioned at the junction of the porous structure with the sleeve. The porous structure is deployed in a patient's stomach such that the anti-migration component sits proximal to the patient's pylorus and prevents migration of the entirety of the device into and through the pylorus. The sleeve extends through the pylorus, into the duodenum and ends in the duodenum or jejunum. Food enters the device from the first opening at the proximal end of the porous structure, passes through the porous structure and sleeve, and exits at the distal end of the sleeve. The device treats obesity by providing a relatively immovable volume occupying structure in the stomach and a bypass for food past the pylorus and proximal portion of the small intestine. Optionally, the device further acts to slow the passage of food through the digestive tract. Patients with the device experience satiety more quickly and have a prolonged sensation of satiety.
