  • Patent number: 7620456
    Abstract: Test procedures for determining a neural stimulation threshold of a patient. In one embodiment, the procedure includes applying a test stimulation signal to the patient and monitoring the patient for a response to the test stimulation signal. The procedure can further include determining a first neural stimulation threshold and calculating a second neural stimulation threshold. The first neural stimulation threshold corresponds to the lowest intensity test stimulation signal that evokes a patient response. The second neural stimulation threshold corresponds to a treatment stimulation signal directed toward affecting a neural activity within the patient.

  • Patent number: 7483747
    Abstract: Systems and methods for enhancing or affecting neural stimulation efficiency and/or efficacy are disclosed. In one embodiment, a system and/or method may apply electromagnetic stimulation to a patient's nervous system over a first time domain according to a first set of stimulation parameters, and over a second time domain according to a second set of stimulation parameters. The first and second time domains may be sequential, simultaneous, or nested. Stimulation parameters may vary in accordance with one or more types of duty cycle, amplitude, pulse repetition frequency, pulse width, spatiotemporal, and/or polarity variations. Stimulation may be applied at subthreshold, threshold, and/or suprathreshold levels in one or more periodic, aperiodic (e.g., chaotic), and/or pseudo-random manners. In some embodiments stimulation may comprise a burst pattern having an interburst frequency corresponding to an intrinsic brainwave frequency, and regular and/or varying intraburst stimulation parameters.

  • Publication number: 20080208291
    Abstract: A telemetry receive unit for use in an implantable medical device or system can include a coil unit, a single-bit analog to digital converter (ADC), a finite impulse response filter (FIR) coupled to the single-bit ADC, and an accumulator coupled to one or more filter taps of the FIR filter. The accumulator, in operation, can produce one or more data recognition signals corresponding to sampled bits at least temporarily stored at the FIR filter. In several examples, the data recognition signals discriminate between frequency modulated signals that are received at the coil unit, including frequency shift keying (FSK) modulated signals.

  • Publication number: 20080161712
    Abstract: Medical device systems and methods for operating medical device systems conserve energy by efficiently managing computational demands of the systems. A first analysis, having relatively lower computational processing demand than at least a second analysis, processes signals from a subject to determine a first estimate of a propensity for the subject to have a neurological event. If the first estimate meets a set of specified criteria, a second analysis is performed to determine a second estimate of the propensity for the subject to have a neurological event.

  • Publication number: 20080161713
    Abstract: Medical device systems and methods for operating medical device systems conserve energy by efficiently managing computational demands of the systems. Signals from a subject are processed and analyzed and an estimate of a propensity for a subject to have a neurological event is determined. Based on the results of the analysis and the estimate, further analysis may be performed and the estimate may be refined. Succeeding cycles of signal measurement and analysis are scheduled depending on the results of the analysis and the estimate. The schedule may be varied temporally or with regard to the types and intensities of analyses performed.

  • Publication number: 20080071323
    Abstract: Aspects of the invention relate to intracranial electrodes and methods for implanting and using intracranial electrodes. In one particular example, an intracranial electrode includes a shaft having a distal contact surface adapted to electrically contact a surface of a patient's brain, a head associated with the shaft, and threads adapted to fix the electrode with respect to the patient's skull. This electrode may have an adjustable length adapted to change a contact force of the distal contact surface against the surface of the brain by adjusting the length of the electrode.

  • Publication number: 20070150024
    Abstract: The present invention provides methods and system for managing neurological disorders such as epilepsy. In one embodiment, the method comprises measuring one or more signals from a patient and processing the one or more signals to characterize a patient's propensity for a future seizure. The characterized propensity for the seizure is thereafter used to determine an appropriate action for managing or treating the predicted seizure; and a recommendation is communicated to the patient that is indicative of the appropriate action.

  • Patent number: 6937892
    Abstract: 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.

  • Publication number: 20050021118
    Abstract: Apparatuses and systems for applying electrical stimulation to a site on a patient. In one embodiment, an implantable electrode assembly includes an electrode array carried by a flexible support member. The electrode array can include a first plurality of electrodes spaced apart from a second plurality of electrodes. The first plurality of electrodes can be connected to a first lead line, and the second plurality of electrodes can be similarly connected to a second lead line. The first and second lead lines can be housed in a cable extending away from the support member. A distal end of the cable can include a connector for coupling the lead lines to an implantable pulse generator or other stimulus unit. In operation, the stimulus unit can bias the first plurality of electrodes at a first potential and the second plurality of electrodes at a second potential to generate an electric field proximate to a stimulation site.
