Patent number: 9750596Abstract: Method and apparatus for limiting absorption of food products in specific parts of the digestive system is presented. A gastrointestinal implant device is anchored in the stomach and extends beyond the ligament of Treitz. All food exiting the stomach is funneled through the device. The gastrointestinal device includes an anchor for anchoring the device to the stomach and a flexible sleeve. When implanted within the intestine, the sleeve can limit the absorption of nutrients, delay the mixing of chyme with digestive enzymes, altering hormonal triggers, providing negative feedback, and combinations thereof. The anchor is collapsible for endoscopic delivery and removal.Type: GrantFiled: September 1, 2015Date of Patent: September 5, 2017Assignee: GI Dynamics, Inc.Inventors: Andy H. Levine, John F. Cvinar, David A. Melanson, John C. Meade

Publication number: 20170172779Abstract: The present invention relates to an anchor configured for minimally-invasive implantation and sized to remain securely positioned within at least a portion of the gastrointestinal tract of an animal. The anchor includes a radial spring formed from an elongated resilient member shaped into an annular wave pattern about a central axis. The anchor defines a central lumen and provides an outward radial force, while allowing for substantial flexure about its perimeter. The anchor is generally removable, but can include fasteners, such as barbs, to further secure it to the surrounding anatomy. In some embodiments, the anchor includes a connector coupling a fixed portion to a removable portion. Further, the anchor can be used to secure a medical device within the body, such as a flexible sleeve within the intestine.Type: ApplicationFiled: March 6, 2017Publication date: June 22, 2017Inventors: John C. MEADE, Andy H. LEVINE, David A. MELANSON, John F. CVINAR

Patent number: 9095416Abstract: A gastrointestinal implant device includes a flexible, floppy sleeve, open at both ends, that extends into the duodenum. The device further includes a collapsible anchor coupled to the proximal portion of the sleeve. The device further includes a drawstring that is threaded through a proximal end of the anchor, and barbs that extend from the exterior surface of the anchor. The collapsible anchor can be a wave anchor. The drawstring can be used to collapse at least a proximal portion of the implant device. This is useful in removing or repositioning the implant device.Type: GrantFiled: June 3, 2014Date of Patent: August 4, 2015Assignee: GI Dynamics, Inc.Inventors: John C. Meade, Andy H.
