  • Patent number: 10568755
    Abstract: A gastrointestinal device and method for retrieving the device are disclosed. The device may include a stent including a plurality of strands forming first and second ends, the strands configured to move between a retrieval configuration, with substantially parallel strands, and a deployed configuration, wherein the strands form proximal and distal portions having first and second diameters larger than the pyloric sphincter. The device may include a connector assembly including proximal, middle, and distal connectors. The middle connector may be coupled to the proximal and distal connectors when the strands are in the deployed configuration. The strands may be attached to the proximal and distal connectors and the first and second ends. The device may include a release mechanism configured to decouple the proximal connector from the middle connector. Decoupling of the proximal and middle connectors may allow the strands to move from the deployed to retrieval configuration.

  • Patent number: 9913744
    Abstract: A gastrointestinal device for reducing flow through a pyloric sphincter of a patient is disclosed. The device may include a stent including a plurality of strands forming first and second ends, the plurality of strands configured to form a proximal portion having a proximal diameter and a distal portion having a distal diameter. The proximal and distal diameters may be larger than a diameter of the pyloric sphincter and the proximal diameter may be larger than the distal diameter. The device may include a connector assembly including proximal and distal connectors, the plurality of strands being attached to the proximal and distal connectors at the first and second ends. The connector assembly may further include a middle portion extending between the proximal and distal connectors. The middle connector may extend within the plurality of strands, and may be unattached to the plurality of strands.

  • Publication number: 20170333241
    Abstract: A gastrointestinal device and method for inserting the device are disclosed. The device may include a stent including a plurality of strands. The stent may move between an insertion configuration, wherein the plurality of strands are substantially parallel, and a deployed configuration, wherein the plurality of strands form a proximal portion having a first diameter and a distal portion having a second diameter. The first and second diameters may be larger than a diameter of the pyloric sphincter. The device may include a connector assembly including proximal and distal connectors attached to the strands. A cable including an engagement portion may be configured to releasably couple to the distal connector and to cause the strands to move from the insertion configuration to the deployed configuration when the engagement portion is coupled to the distal connector and force is applied to the cable in a direction toward the proximal connector.
