  • Publication number: 20200093585
    Abstract: A gastroenterologic sleeve is anchored within the digestive tract, without tissue-puncturing mechanisms, by providing anchoring mechanisms that utilize the inherent shape of the stomach to prevent sleeve migration. In at least two embodiments, the anchoring mechanism expands to conform to the interior stomach walls. In other embodiments, internal pessary rings are held in place at the gastroesophageal junction by an external band. A delivery device is provided for implanting the various device transesophageally.

  • Patent number: 9909231
    Abstract: A method for recharging a crucible with polycrystalline silicon comprises adding flowable chips to a crucible used in a Czochralski-type process. Flowable chips are polycrystalline silicon particles made from polycrystalline silicon prepared by a chemical vapor deposition process, and flowable chips have a controlled particle size distribution, generally nonspherical morphology, low levels of bulk impurities, and low levels of surface impurities. Flowable chips can be added to the crucible using conventional feeder equipment, such as vibration feeder systems and canister feeder systems.

  • Publication number: 20150374524
    Abstract: A device for isolating tissue in the digestive tract including a biocompatible portion having a surface sized to cover the tissue to be isolated and also includes a plurality of micro-anchors attached to the biocompatible portion and extending from the surface, the micro-anchors sized to penetrate the mucosa of the tissue. A method for isolating tissue in the digestive tract in which an isolation element is delivered to a desired location in the digestive system; the isolation element having fixed thereto a plurality of micro-anchors. The method also includes attaching the isolation element to tissue at the desired location by causing the micro-anchors to penetrate the mucosa of the tissue.
