  • Patent number: 9005121
    Abstract: A system and method tests the gastric valve and urethral sphincter in a patient. A contrast agent is administered into the esophagus of a patient followed by inducing an involuntary reflex cough epoch within the patient to isolate the gastric valve from the lower esophageal sphincter (LES) and isolate the external urethral sphincter from the internal urethral sphincter. An imaging sensor detects the flow of the contrast agent during the involuntary reflex cough epoch and determines whether stomach reflux occurred indicative of a malfunctioning gastric valve. A determination is made if urine leakage occurs indicative of stress urinary incontinence (SUI).

  • Publication number: 20140288612
    Abstract: A system to prevent incontinence in a patient includes transducers positioned subcutaneously at the interior surface of the medial border of the costal margin of at least one of ribs 8, 9 and 10 that detect movement of at least one of those ribs and generates signals indicative of that movement during the inspiratory phase of respiration. Muscle stimulators include electrodes connected to muscles of the urethral sphincter. A controller is connected to the electrodes and the transducers. This controller receives the signals generated from the transducers indicative of the movement of the ribs during the inspiratory phase of respiration and in response, generates and transmits electrical control signals to the electrodes connected to the muscles of the urethral sphincter to stimulate electrically the muscles of the urethral sphincter to close the urethral sphincter during the inspiratory phase of respiration.
