  • Publication number: 20190336268
    Abstract: Luminal devices are described. In one embodiment, a luminal device includes an esophageal stent and an anchoring membrane coupled to the esophageal stent. The anchoring membrane may be configured to be coupled to an esophageal wall with a tissue anchor placed through the anchoring membrane. The anchoring membrane may be configured to be pierced to allow the tissue anchor to be placed through the anchoring membrane. Methods for attaching a luminal device to the esophageal wall are described. In one embodiment, a method may include forming a bulge in an anchoring membrane of the luminal device and the esophageal wall, piercing the bulge from a first side of the anchoring membrane and a first side of the esophageal wall, placing a second retention element of a tissue anchor on a second side of the esophageal wall; and placing a tension element of the tissue anchor through the anchoring membrane and the esophageal wall. The tension element may be coupled to the second retention element.

  • Patent number: 10368973
    Abstract: Gastrointestinal bypass devices are described. In one embodiment, a gastrointestinal bypass device may include an anchoring membrane configured to be attached to a wall of an esophagus with a tissue anchor placed through the anchoring membrane. The anchoring membrane may be configured to be pierced to allow the tissue anchor to be placed through the anchoring membrane. Methods for attaching a device to a tissue wall are described. In one embodiment, a method may include forming a bulge in an anchoring membrane of the device and the tissue wall, piercing the bulge from a first side of the anchoring membrane and a first side of the tissue wall, placing a second retention element of a tissue anchor on a second side of the tissue wall, and, placing a tension element of the tissue anchor through the anchoring membrane and the tissue wall. The tension element may be coupled to the second retention element. The method may further include placing a first retention element on the first side of the anchoring membrane.

  • Patent number: 10226324
    Abstract: Delivery devices are described. In one embodiment, a delivery device includes a catheter and a sealing pad coupled to an outer surface of the catheter. The delivery device may further include a recess formed in an outer surface of the catheter. The sealing pad may be coupled in the recess. Methods for delivering a tubular device are described. In one embodiment, a method may include inserting a distal end of a catheter into a lumen of a tubular device. The catheter may include a sealing pad coupled to an outer surface of the catheter. The method also includes positioning the sealing pad inside a drawstring coupled circumferentially to the tubular device, and cinching the drawstring around the catheter at the sealing pad to couple the tubular device to the catheter.

  • Publication number: 20180000622
    Abstract: Devices and methods for gastrointestinal bypass are described. A gastrointestinal bypass device includes a gastrointestinal cuff and a gastrointestinal sleeve. The cuff may be configured to be attached in the esophagus, and may be sufficiently flexible to expand and collapse to conform with the inside of the esophagus to allow the esophagus to function substantially normally. The sleeve is configured to be coupled to the cuff, and may be made of a material that is floppy or flaccid but does not substantially expand radially.

  • Patent number: 9757264
    Abstract: A gastrointestinal bypass device for directing food and liquids from an esophagus and/or a proximal portion of a stomach into an intestines is described. The device comprises a receiver, a sleeve, and a device coupling. The receiver may be configured to be positioned in the esophagus and/or the stomach. A proximal portion of the receiver may be configured to open and close to at least partially conform to an inside of the esophagus and/or a proximal portion of the stomach. The receiver may be configured to receive food and liquids from the esophagus and/or a proximal portion of the stomach into a lumen of the receiver. The sleeve may be coupled to a distal portion of the receiver. The sleeve may be configured to be positioned in the stomach and the intestines. The sleeve may have a lumen in communication with the lumen of the receiver. The sleeve may be configured to direct the food and the liquids from the receiver into the intestines.
