The higher of the two frequencies is superimposed on the lower frequency, creating a current intensity window as an envelope along a profile of the lower frequency. The mixed electrical signal is automatically applied for a pre-determined period of time, and amplitude and/or duration and/or frequencies is varied according to a pre-set schedule programmed into a controller coupled to the one or more electrodes.

  • Patent number: 9693708
    Abstract: The invention relates to wireless biotelemetry of low level bioelectric and biosensor signals by directly modulating the backscatter of a resonant circuit. Low level electrical analog or digital signals are directly applied to a resonant circuit containing a voltage-variable capacitor such as a varactor diode, that proportionally shifts the resonant frequency and so amplitude of radiofrequency backscatter in a way that represents analog bioelectric or biosensor waveform data. By strongly driving the resonant circuit with a radiofrequency source, a voltage variable capacitance can be caused to amplify the bio-signal level by a parametric process and so provide sufficient sensitivity to telemeter for low millivolt and microvolt level signals without additional amplification. A feature of the device is its simplicity and that it accomplishes both modulation and preamplification of low level sensor signals by the same variable capacitance circuit which reduces the device size and power consumption.

  • Patent number: 9616225
    Abstract: The present specification discloses devices and methodologies for the treatment of GERD. Individuals with GERD may be treated by implanting a stimulation device within the patient's lower esophageal sphincter and applying electrical stimulation to the patient's lower esophageal sphincter, in accordance with certain predefined protocols. The presently disclosed devices have a simplified design because they do not require sensing systems capable of sensing when a person is engaged in a wet swallow, have improved energy storage requirements, enable improved LES function while concurrently delivering additional health benefits, and enable improved LES function post stimulation termination.

  • Patent number: 9433783
    Abstract: Techniques for managing urinary or fecal incontinence include delivering a first type of therapy to generate a first physiological response and, upon detecting a trigger event, delivering a second type of therapy to generate a second physiological response. The first type of therapy can be delivered on a substantially regular basis, while the second type of therapy is delivered as needed to provide an additional boost of therapy. The trigger event for activating the delivery of the second type of therapy may include input from a sensor that indicates a bladder condition, patient activity level or patient posture, or patient input. In some examples, the therapy is stimulation therapy.

    Abstract: A method and system for bladder control are disclosed. In embodiments, a method for bladder control is provided that comprises coupling an electrode to an afferent nerve that is related to the bladder. Applying a plurality of pulse burst stimulations via the electrode causes voiding of urine from the bladder. In embodiments, the plurality of pulse burst stimulations to the afferent nerve reduces external urethral sphincter (EUS) contractions and evokes bladder contractions to expel urine from the subject. In embodiments, the plurality of pulse burst stimulations to the afferent nerve evokes bladder contractions alone to expel urine from the subject. In embodiments, a system for bladder control is provided that comprises an electrode for applying a pulse burst stimulus to an afferent nerve or dermatome to reduce reflex contractions and a signal generator for generating the pulse burst stimulus.
