  • Publication number: 20190008669
    Abstract: 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.

  • Publication number: 20170143523
    Abstract: A variety of passive intragastric implant devices for obesity treatment are disclosed. Such passive implants do not autonomously change shape, but instead react within the stomach to induce satiety. The implants may take up volume within the stomach, thus reducing the digestive capacity. Additionally, the implants may contact areas within the stomach, such as the cardia surrounding the esophageal sphincter, to stimulate satiety-inducing nerves. Also, a number of implants slow gastric emptying by blocking or otherwise impeding flow through the pyloric sphincter. Other implants delay digestion by providing a duodenal sleeve. A number of implants combine two or more of these satiety-inducing features. Methods of implant are disclosed including compressing the implants within a delivery tube and transorally advancing the implants through the esophagus to be deployed within the stomach. Removal of the implants occurs in the reverse.

  • Publication number: 20170086818
    Abstract: A suture cinch, cinch applicator, and cinch loader for loading the cinch into the applicator are provided and permit re-use of the applicator with multiple cinches during an endoscopic procedure. The applicator can be loaded with a first cinch, apply the first cinch onto a portion of suture to fix the portion of suture relative to anatomical tissue, reloaded with a second cinch optionally using the loader, and subsequently used to apply the second cinch to fix another portion of suture to fix the other portion of suture relative to anatomical tissue. The cinch is a unitary tubular member through which the suture can be advanced when the cinch is loaded within the applicator. The cinch defines multiple ribs and a cutter in a wall thereof. Operation of the applicator deforms the ribs inward to retain the cinch on the suture and displaces the cutter to sever the suture.

  • Publication number: 20170065444
    Abstract: Transoral obesity treatment devices and related methods for operation thereof are described which occupy space within a stomach and/or stimulate the stomach wall. The transoral obesity treatment devices and related methods are intended to assist a patient in maintaining a healthy body weight. Features of the devices include insertion transorally and without invasive surgery, without associated patient risks of invasive surgery, and without substantial patient discomfort. The life span of these devices may be material-dependent upon long-term survivability within an acidic stomach, but is intended to last one year or longer. The devices have the capacity to vary in size and are desirably self-actuating in that they change shape and/or volume using internal motors or actuators. The changing character of the devices helps prevent the person's stomach from compensating for the implant, such as sometimes happens with static intragastric devices.
