  • Patent number: 11707621
    Abstract: A method for spinal cord stimulation treatment includes positioning eight implantable electrodes to a dura matter in an epidural space proximate to a subject's spinal cord so that (i) a first circuit is created between a first and second electrode on a first channel, (ii) a second circuit is created between a third and fourth electrode on a second channel, (iii) a third circuit is created between a fifth and sixth electrode on a third channel, and (iv) a fourth circuit is created between a seventh and eighth electrode on a fourth channel, transmitting signals through the first and second circuits that interfere to produce a first beat signal, transmitting signals through the third and fourth circuits that interfere to produce a second beat signal, and interaction of the first and second beat signals results in a combined beat signal proximate to the subject's spinal cord.

  • Patent number: 11007364
    Abstract: A stimulator and a method using electrical stimulation of a spinal cord, for providing positive regulation of multiple symptoms other than pain is disclosed. An example method includes positioning a first pair of implantable electrodes to a dura matter in an epidural space proximate to a subject's spinal cord at predetermined locations, positioning a second pair of implantable electrodes to the dura matter in the epidural space proximate to the subject's spinal cord at predetermined locations, and transmitting signals of first and second frequencies through the first and second pairs of implantable electrodes respectively, so that the signals of the first and second frequencies interfere with each other to produce at least one beat signal proximate to the subject's spinal cord. The at least one beat signal has a frequency within a range of more than 250 Hz to about 15,000 Hz.

  • Patent number: 10953227
    Abstract: A stimulator and a method for the treatment of intractable pain syndromes by electrical stimulation of the spinal cord is disclosed in which implantable electrodes positioned around a targeted area of the spinal cord transmit an interferential current that has a base medium frequency alternating current between 500 Hz-20 KHz. A digital signal processor generates a sine-wave-like waveform from a pulse generator which after further processing is used to generate at least two circuits for use in producing the beat frequency signal. An effective area of stimulation is controlled by the quantity of electrodes, positioning of the electrodes and electrode cross pattern orientation. Amplitude modulation of electrical circuits created at the electrode placements also augments the effective area of stimulation. The stimulator and method reduce accommodation of the body to the electrical stimulation and provide deeper penetration of the resultant signal.
