    摘要： 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.

    摘要： A stimulator and a method for the treatment of intractable pain syndromes by electrical stimulation of the spinal cord 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.

    摘要： Methods and apparatuses for deploying percutaneous probes. An apparatus in accordance with one embodiment of the invention includes a housing and a percutaneous probe having a sharp end and positioned within the housing. The percutaneous probe is movable relative to the housing between a stowed position and at least one of a first deployed position and a second deployed position. The percutaneous probe can project from the housing by a first distance when in the first deployed position and a second distance greater than the first distance when in the second deployed position. A depth control device can operatively couple to the percutaneous probe and can have a first configuration to allow the percutaneous probe to be moved to the first deployed position and a second configuration to allow the percutaneous probe to be moved to the second deployed position.

    摘要： A method and apparatus for administering percutaneous electrical therapy to a recipient. The apparatus can include an electrical coupler having a coupling member configured to be removably positioned at least proximate to a percutaneous probe. The coupling member can be coupleable to a source of therapeutic electrical signals via a therapeutic signal transmission link to transmit the therapeutic electrical signals to the recipient. The apparatus can further include a status signal transmission link at least proximate to the therapeutic signal transmission link and coupleable to a status signal emitter. The status signal transmission link can be at least tamper-resistant and/or tamper-evident, and can be configured to transmit a status signal having a first characteristic value when the status signal transmission link is in a first condition and a second characteristic value when the status signal transmission link has been altered from a first condition to a second condition.

    摘要： The invention is a percutaneous electrical therapy system with sharp point protection. In a preferred embodiment, the system includes a control unit; an electrode assembly adapted to deliver electrical therapy to a patient, where the electrode assembly has an electrode electrically connectable to the control unit, the electrode having a sharp point at a distal end adapted to be inserted into the patient's tissue; and a sharp point protection assembly operable with the electrode assembly for reducing risk of unintended exposure to the electrode's point. The invention also includes an electrode assembly and sharp point protection assembly for a percutaneous electrical therapy system as described above, apart from the control unit. The invention is also a method of performing percutaneous electrical therapy, the method including the steps of providing an electrode assembly having an electrode, the electrode having a sharp point at a distal end; inserting the sharp point of the electrode into a patient's tissue without exposing the sharp point to anyone but the patient; and applying an electrical signal to the electrode from a control unit.

    摘要： 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.
