  • Patent number: 8016851
    Abstract: A delivery system and method of use thereof for introducing a bundled intragastric bag into a gastric lumen are described. The delivery system includes a pushing mechanism movable between an unexpanded and expanded configuration. The pushing mechanism in its expanded configuration pushes each of the bundles of the bag into the gastric lumen. A suture strand is periodically pulled during the procedure to help create doughnut-shaped bundles. Another suture strand extends between a proximal button and distal button of the deployed assembly to maintain the doughnut-shaped bundle structure.

  • Publication number: 20110144662
    Abstract: The present embodiments provide clip devices, along with systems and methods for delivering and deploying the clip devices. An exemplary clip device comprises inner and outer segments, and further has a delivery configuration, a tissue receiving configuration and a deployed configuration. A distal region of the outer segment is movable with respect to a distal region of the inner segment, thereby creating a spacing between the inner and outer segments for surrounding tissue in the tissue receiving configuration. The inner and outer segments may be biased to return to the deployed configuration, and may comprise generally identical shapes in the deployed configuration wherein the outer segment is proportionally larger than the inner segment. In one embodiment, the inner and outer segments each comprise “V” shapes in the unbiased state. Various delivery systems and methods are provided for delivering and deploying the clip devices disclosed.

  • Publication number: 20110106107
    Abstract: The present embodiments provide apparatus and methods for treating tissue by applying a force to the tissue. In one embodiment, the apparatus comprises a deployable segment having proximal and distal regions, a main body extending therebetween, and a loop member formed at the distal region of the deployable segment. A cannula having a bore is dimensioned to circumferentially surround at least a portion of the main body at a location proximal to the loop member, and a spring member is disposed between the cannula and the loop member. The proximal end of the spring member is affixed to the cannula, and the distal end of the spring member is movable to apply a compressive force to adjust the size of the opening of the loop member and compress tissue disposed within the opening of the loop member. In an alternative embodiment, the cannula is omitted, and a diameter of the loop member is configured to be reduced and increased any number of times before final deployment of the deployable segment.
