Patent number: 10111771Abstract: A bariatric device 10 for use in inducing weight loss, comprising a cardiac element 12, a pyloric element 26, and a connecting element 25 between the two other elements, wherein the connecting element 25 provides structure between the cardiac 12 and pyloric 26 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 12 and pyloric 26 elements may be symmetrical, so that the device can orient itself either way in the stomach and still achieve the weight loss function. Alternatively, the cardiac 12 and/or pyloric 26 elements may have a restriction element to slow gastric filling or emptying, to produce a satiety signal.Type: GrantFiled: July 7, 2015Date of Patent: October 30, 2018Assignee: Apollo Endosurgery US, Inc.Inventors: Janel Birk, Daniel Dongelmans

Patent number: 10070980Abstract: An intragastric implant for obesity treatment is disclosed. The device delays digestion by providing a duodenal sleeve, and may also slows gastric emptying by limiting flow through the pyloric sphincter. The implant includes an elongated axially-compressible duodenal sleeve having a non-tissue-piercing anchor on a proximal end sized to lodge within the duodenal bulb. The anchor may have oppositely-directed anchoring flanges to resists migration in both directions. The sleeve may also have barbed ribs to resist proximal movement back up into the stomach. A method of implant includes collapsing/compressing the device and transorally advancing it through the esophagus to be deployed within the duodenum. A dissolvable jacket may constrain the implant for delivery and naturally dissolve upon implant. Removal of the implant may occur in the reverse.Type: GrantFiled: June 18, 2013Date of Patent: September 11, 2018Assignee: APOLLO ENDOSURGERY US, INC.Inventors: Mitchell H. Babkes, Zachary P.

Patent number: 9956105Abstract: A variety of passive intragastric implant devices for obesity treatment are disclosed. Such passive devices do not autonomously change shape, but instead react within the stomach to induce satiety. The devices may provide slowed entry into the stomach, thus reducing the intake capacity. Additionally, the devices may contact areas within the stomach, such as the cardia surrounding the esophageal sphincter, to stimulate satiety-inducing nerves. Some devices combine two or more of these satiety-inducing features. Methods of implant are disclosed including compressing the devices within a delivery tube and transorally advancing the devices through the esophagus to be deployed within the stomach. Removal of the devices occurs in the reverse. The implants are formed of materials that permit the implant to be compressed into a substantially linear transoral delivery configuration and that will resist degradation over a period of at least six months within the stomach.Type: GrantFiled: October 14, 2015Date of Patent: May 1, 2018Assignee: Apollo Endosurgery US, Inc.Inventors: Mitchell H.
