  • Patent number: 8831737
    Abstract: The disclosure describes a system that measures the distance between one or more electrodes and tissue of a patient, and controls one or more parameters of the stimulation delivered to the tissue by the electrodes based on the measured distance. The system controls the measurement of the distance between the electrodes and the tissue as a function of activity of the patient. The system uses, for example, a piezoelectric transducer to sense activity of the patient, and may determine whether or how frequently to measure the distance between electrodes and tissue based on the sensed physical activity. A piezoelectric transducer may be used both to sense activity and to measure the distance between the electrodes and the tissue.

  • Patent number: 8825175
    Abstract: Techniques for adjusting stimulation are disclosed. A medical device measures an impedance associated with one or more electrodes, e.g., the impedance presented to the medical device by a total electrical circuit that includes the one or more electrodes, the conductors associated with the electrodes, and tissue proximate to the electrodes. The medical device stores at least one patient-specific relationship between impedance and a stimulation parameter, and adjusts the value of the stimulation parameter based on the measured impedance according to the relationship. The medical device may store multiple relationships, and select one the relationships based on, for example, an activity level of the patient, posture of the patient, or a current stimulation program or electrode combination used to deliver stimulation. By adjusting a stimulation parameter, such as amplitude, according to such a relationship, the stimulation intensity as perceived by the patient may be kept substantially constant.

  • Patent number: 8738153
    Abstract: In some examples, an extension includes a connector adapted to electrically couple to a proximal end of the therapy delivery element. An elongated extension body is attached to the connector. The elongated extension body includes a stylet coil having a stylet coil lumen. The stylet coil extends within the elongated extension body to the connector. A conductor assembly includes a plurality of insulated electrical conductors braided to extend around the stylet coil and electrically coupled to the connector. The conductor assembly includes an inner lumen with a diameter greater than an outside diameter of the stylet coil, wherein axial elongated of the elongated extension body reduces the inner diameter of the conductor assembly. A low durometer insulator extends around the conductor assembly. A stylet is sized to slide freely within the stylet coil lumen during implantation of the extension in the living body.

  • Patent number: 8738155
    Abstract: A method and neurostimulation control system for operating two leads disposed adjacent tissue of a patient are provided. A plurality of cross-lead electrical parameters are measured to generate a measured electrical profile of the electrode leads. A plurality of cross-lead electrical parameters are estimated to generate a first reference electrical profile for the electrode leads in a first known staggered configuration. The first reference electrical profile is spatially shifted to generate a second reference electrical profile for the electrode leads in a second known staggered configuration. The measured electrical profile is compared to the first and second reference electrical profiles, and a longitudinal stagger between the electrode leads is quantified based on the comparison.

    Abstract: Selective high-frequency spinal cord modulation for inhibiting pain with reduced side effects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient's spinal cord region to address low back pain without creating unwanted sensory and/or motor side effects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.

  • Patent number: 8731687
    Abstract: An MRI compatible electrode circuit construct is provided. The construct includes at least two filter components constructed from an electrode wire. One filter component may be a resonant LC filter at or near an electrode/wire interface that resolves the issue of insufficient attenuation by effectively blocking the RF induced current on the wire from exiting the wire through the electrode. The second filter component may include one or more non-resonant filter(s) positioned along the length of the electrode wire that resolve(s) the issue of excessive heating of the resonant LC filter by significantly attenuating the current induced on the wire before it reaches the resonant LC filter. The non-resonant filter(s) may also attenuate the RF current reflected from the resonant LC filter thereby resolving the issue of the strong reflected power from the resonant filter and the associated dielectric heating.

  • Publication number: 20140128955
    Abstract: A method for treating intractable pain via electrical stimulation of the spinal cord. Remote, non-contact stimulation of a selected region of spinal cord is achieved by placement of a transceiver patch directly on the surface of that region of spinal cord, with said patch optionally being inductively coupled to a transmitter patch of similar size on either the outer or inner wall of the dura surrounding that region of the spinal cord. By inductively exchanging electrical power and signals between said transmitter and transceiver patches, and by carrying out the necessary electronic and stimulus signal distribution functions on the transceiver patch, the targeted dorsal column axons can be stimulated without the unintended stray stimulation of nearby dorsal rootlets. Novel configurations of a pliable surface-sheath and clamp or dentate ligament attachment features which realize undamaging attachment of the patch to the spinal cord are described.

  • Patent number: 8718789
    Abstract: Devices, systems and methods are described by which the blood pressure, nervous system activity, and neurohormonal activity may be selectively and controllably reduced by activating baroreceptors. A baroreceptor activation device is positioned near a baroreceptor, preferably a baroreceptor located in the carotid sinus. A control system may be used to modulate the baroreceptor activation device. The control system may utilize an algorithm defining a stimulus regimen which promotes long term efficacy and reduces power requirements/consumption. The baroreceptor activation device may utilize electrodes to activate the baroreceptors. The electrodes may be adapted for connection to the carotid arteries at or near the carotid sinus, and may be designed to minimize extraneous tissue stimulation.
