  • Patent number: 9403001
    Abstract: Devices, systems and methods are disclosed for treating or preventing gastroparesis, functional dyspepsia, and other functional gastrointestinal disorders. The methods comprise transmitting impulses of energy non-invasively to selected nerve fibers, particularly those in a vagus nerve. The methods provide damaged interstitial cells of Cajal (ICC) with trophic factors via vagal afferent nerve fibers, thereby reversing ICC damage, and as a consequence improving gastric motility. The methods also increase levels of inhibitory neurotransmitters in the brain so as to decrease neural activity within the area postrema, or they deactivate a resting state neural network containing parts of the anterior insula and anterior cingulate cortex, which will thereby reduce abnormal interoception and visceral hypersensitivity.

  • Patent number: 7643861
    Abstract: A chronic subdermal silver-silver/chloride (Ag—Ag/Cl) electrode for the recording of biopotentials is disclosed. The electrode is comprised of an Ag—Ag/Cl distal end that is placed subdermally by various methods. The recording electrode is made of solid, multi-stranded or a ball of pure silver and the whole length of the electrode is insulated except for the distal end which is used for voltage recordation. The electrode can be placed subdermally by an introducer apparatus such as hypodermic or sewing needle, a split-cannula, a staple, or a suture. Once placed, the introducer apparatus can be removed leaving the recording wire/element in place. The recording electrode can be placed at any location on the body to record the local biopotential (EEG, EOG, EMG, EKG, etc). It can be left in place for hours, days, or weeks, as it will record without any further adjustment.

  • Patent number: 7299083
    Abstract: A chadd disposed on a patient's skin generates heat at a substantially constant temperature for an extended period of time (e.g., hours and days) when exposed to air. The chadd becomes porous when heated and produces a porosity in the patient's skin as a result of the heat generation to pass ions through the pores in patient's skin to a layer disposed on the chadd. The layer (e.g., silver or silver chloride) has properties of converting the ions to electrons. The electrons pass to an electrical lead disposed on the layer. The electrical lead passes an electrical signal (produced from the electrons) to a terminal. An amplifier connected to the terminal amplifies the signal without changing the characteristics of the signal and without producing noise.

  • Patent number: RE38695
    Abstract: A medical extravasation device has an electrode patch that can attach to the skin for sensing electrical information. Tissue impedance is calculated from the electrode patch signals. The patch has elongate pick-up electrodes inboard of elongate energizing electrodes. The measuring zone determined by the elongate space between the pick-up electrodes enhances sensitivity and specificity. The presence of an extravasation is determined by interpreting the tissue impedance measurement. The method for determining the extravasation includes a first step of determining a pre-injection baseline measurement of the tissue impedance. Then, the tissue impedance is monitored during the procedure itself. A predetermined amount of change in tissue impedance is determined to indicate an extravasation.

  • Patent number: RE38879
    Abstract: The technique for detecting extravasation during the injection of fluid into a patient involves the establishment of a baseline representing impedance at the zone of the injection prior to the injection starting. Extravasation is signaled when at least two characteristics appear. First is that the impedance varies from the baseline more than a predetermined amount in more than a predetermined number of discreet time slots called epochs herein. Second is that, the rate of change of the impedance, which is called the slope herein, is consistently greater than a predetermined amount.
