  • Publication number: 20170224986
    Abstract: A device, system and method for diagnosing and treating gastric disorders is provided. A submucosal gastric implant device is placed within the submucosal layer of a patient's stomach wall. The device in one embodiment provides electrical stimulation of the stomach wall and may use multiple electrode pairs for sequential stimulation. The device may also have other functional aspects such as a sensor for sensing various parameters of the stomach or stomach environment, or a therapeutic delivery device. The implant may be programmed to respond to sensed information or signals. The device may be modular with a portion of the device accessible outside the stomach wall for removal and replacement. An endoscopic delivery system prepares and delivers the functional device through the esophagus and into the stomach where it is placed through an opening in the mucosa into the submucosal layer of the stomach wall.

  • Publication number: 20170050006
    Abstract: A device and method for mapping, diagnosing and treating the intestinal tract is provided using a capsule passing through the intestinal tract. Further, a capsule tracking system is provided for tracking a capsule's location along the length of an intestinal tract as various treatment and/or sensing modalities are employed. In one variation, an acoustic signal is used to determine the location of the capsule. A map of sensed information may be derived from the pass of a capsule. Capsules may be subsequently passed through to treat the intestinal tract at a determined location along its length. One variation uses an electrical stimulation capsule to treat and/or diagnose a condition in the intestinal tract.

  • Patent number: 7371215
    Abstract: A device, system and method for diagnosing and treating a patient is provided where a functional device is attached to a stomach wall. The device in one embodiment provides electrical stimulation of the stomach wall. The device may also have other functional aspects such as a sensor for sensing various parameters of the stomach or stomach environment, or a substance delivery device. The implant may be programmed to respond to sensed information or signals. The device may be modular with a portion of the device accessible for removal and replacement. In one embodiment, an endoscopic delivery system delivers the functional device through the esophagus and into the stomach where it is attached the stomach wall with the assistance of a suction used to stabilize the tissue of the stomach wall. The device includes a chamber for receiving tissue of the stomach wall for attachment where a vacuum pressure is applied through the chamber to draw the tissue into the chamber.

  • Patent number: 6824515
    Abstract: The present invention provides ultrasound-guided ablation catheters and methods for their use. In one embodiment, a tissue ablation apparatus (2) includes a flexible elongate body (12) having proximal (14) and distal (12) ends. A plurality of spaced-apart electrodes (24) are operably attached to the flexible body near the distal end. A plurality of transducer elements (28) are disposed between at least some of the electrodes. Transducers assist the physician in determining whether or not the ablation elements are in contact with the tissue to be ablated.

  • Patent number: 6522913
    Abstract: A catheter tube carries an imaging element for visualizing tissue. The catheter tube also carries a support structure, which extends beyond the imaging element for contacting surrounding tissue away from the imaging elements, the imaging element being movable with the support structure. The support element stabilizes the imaging element, while the imaging element visualizes tissue in the interior body region. The support structure also carries a diagnostic or therapeutic component to contact surrounding tissue.
