  • Patent number: 9265596
    Abstract: An implant (100) includes a protrusion (110) with an open or rounded loop (112) (or open head) connected to a collapsible anchor. The protrusion may include a straight length of wire (114) or a helical length wire, with one or more wire loops (112) at the end of the length forming the loop. Upon deployment within the gastrointestinal tract, the protrusion expands from a collapsed state, alongside the anchor, to a relaxed state, in which the protrusion extends outward from the anchor. As the protrusion expands to its relaxed state, it pushes the loop into the wall of the duodenum, causing the loop to penetrate the duodenal wall. A pocket of scar tissue forms about the head and possibly through an opening in the head, securing the anchor within the duodenum. The implant may also include a thin-walled sleeve that is coupled to the anchor and extended from the anchor into the intestine.

  • Publication number: 20150190259
    Abstract: A gastrointestinal implant device (2800) comprises a planar proximal element (220) configured to reside in a stomach to resist distal migration, a distal element (222) configured to reside in an intestine to resist proximal migration and one or more tethers (224) coupling the planar proximal element to the distal element.

  • Publication number: 20140358063
    Abstract: An implant includes a collapsible anchor to be deployed within a lumen and a protrusion coupled to the anchor. The protrusion, in a constrained state, extends a distance from an exterior surface of the anchor and, in an unconstrained state, extends further from the exterior surface of the anchor. Also included is a biodegradable constraint, such as a biodegradable tube or suture, configured to maintain the protrusion in the constrained state until the constraint releases. The implant may include additional biodegradable constraints, each constraint configured to maintain the protrusion in a different constrained state and to degrade over a different predetermined period after the implant has been deployed within the lumen. The protrusion may include a bi-directional barb or an open loop. The protrusion may be configured to penetrate a wall of the lumen and to allow tissue to grow about the protrusion.

  • Publication number: 20140296770
    Abstract: Gastrointestinal implants can be used to secure thin-walled sleeves, restrictor plates, and other devices within the gastrointestinal tract. An example implant includes three elements: a stomach anchor to resist distally oriented forces; a duodenal anchor to resist proximally oriented forces; and a connector element to keep the stomach anchor fixed relative to the stomach anchor. The implant is inserted into the gastrointestinal tract with a delivery device that holds the implant in a compressed state for minimally invasive delivery until the implant is positioned properly. Upon releasing from the delivery device, the implant expands to a relaxed state across the pylorus, allowing prongs that extending outward from the stomach and duodenal anchors to engage tissue in the gastrointestinal tract. The deployed implant may also include a thin-walled sleeve that extends into the intestine from the stomach anchor, duodenal anchor, or connector element.

  • Patent number: 8365931
    Abstract: The specification discloses a device (10) insertable into a wine bottle (12) after opening, the device (10) being intended to float on the surface (21) of wine remaining in the bottle (12) and minimize deterioration of the remaining wine, said device (10) including a core structure (11) having a thin spring plate (11a) capable of being deformed when the device (10) is inserted into the bottle (12) and capable of recovering its shape once inserted into the bottle (12), the core structure (11) further having at least one floatation means (11b) and said device (10) including a liquid impervious outer sheath (18) having upper and lower walls (14, 15) sealed to one another to retain the core structure (11) therein, the outer sheath (18) being of a material that is non reactive with wine and including a flexible outer peripheral edge zone (42) with cuts or the like (49) formed therein, the outer peripheral edge zone (42) being adapted, in use, to contact the internal surfaces of the wine bottle (12) while floating

  • Publication number: 20120150365
    Abstract: A wireless precision avionics kit is provided for retrofitting aircraft to facilitate communication between the cockpit and modern military stores without hardware or software modifications to the aircraft. The store includes an electrical interface that requires data and possibly power from the aircraft and provides for communication via a message set. The kit may be used with any aircraft that provides a rack or pylon for mounting the store and the capability to release the store. The kit may be used with aircraft having no existing capability to communicate with smart stores, with aircraft having an incompatible interface for modern stores or even with aircraft that have a compatible hardware interface for which the software is outdated.
