  • Patent number: 10279183
    Abstract: Systems and methods for detecting intrathecal penetration are disclosed. A method in accordance with one embodiment includes detecting a value corresponding to an impedance of an electrical circuit that in turn includes an electrical contact located within the patient, and patient tissue adjacent to the electrical contact. The method further includes comparing the detected value to a predetermined criterion, and, if the detected value meets the predetermined criterion, identifying penetration of the patient's dura based at least in part on the detected value.

  • Publication number: 20180296828
    Abstract: A method for determining whether the relative position of electrodes used by a neurostimulation system has changed within a patient comprises determining the amplitude of a field potential at each of at least one of the electrodes, determining if a change in each of the determined electric field amplitudes has occurred, and analyzing the change in each of the determined electric field amplitudes to determine whether a change in the relative position of the electrodes has occurred. Another method comprises measuring a first monopolar impedance between a first electrode and a reference electrode, measuring a second monopolar impedance between second electrode and the reference electrode, measuring a bipolar impedance between the first and second electrodes, and estimating an amplitude of a field potential at the second electrode based on the first and second monopolar impedances and the bipolar impedance.

  • Publication number: 20180207432
    Abstract: Tissue stimulation systems generally include a pulse generating device for generating electrical stimulation pulses, at least one implanted electrode for delivering the electrical stimulation pulses generated by the pulse generating device, and a programmer capable of communicating with the pulse generating device. Stimulation pulses may be defined by several parameters, such as pulse width and amplitude. In methods of stimulating the tissue with the stimulation system, a user may adjust one of the parameters such as pulse width. The programmer may automatically adjust the pulse amplitude in response to the change in pulse width in order to maintain a substantially constant effect of the stimulation pulses.

  • Patent number: 9907957
    Abstract: The invention is a system and method for detecting the status of a rechargeable battery included within an implantable medical device. The medical device can incorporate a status indicator which signals the user concerning the battery status, e.g., low battery level. The signal may be audible or it may arise from an electrical stimulation that is perceptually distinguished from the operative, therapeutic stimulation. The external programmer may also incorporate a second battery status indicator that is visual, audible, or physically felt. Battery status data may be conveyed on visual displays on the external programmer by uploading this information from the medical device using a bi-directional telemetry link. Such battery status data are helpful to the user to indicate when the battery should be recharged and to the clinician to monitor patient compliance and to determine end-of-useful life of the rechargeable battery.

  • Patent number: 9895538
    Abstract: Methods for identifying responders to paresthesia-free stimulation therapy, and associated systems are disclosed. A representative method comprises implanting a pair of spinal cord signal delivery devices and connecting an external signal generator thereto. A plurality of the electrical contacts are simultaneously activated with a high frequency signal without causing paresthesia in the patient, wherein the electrical contacts would cause paresthesia in the patient if activated with a low frequency signal. The high frequency signal is in a range of from about 3 kHz to about 20 kHz and an amplitude of less than 4 mA. If the patient responds favorably, a signal generator is implanted in the patient. A second high frequency signal is then applied to fewer than the plurality of electrical contacts.

  • Patent number: 9878166
    Abstract: A method, computer medium, and system for programming a controller is provided. The controller controls electrical stimulation energy output to electrodes, and stores a set of programmed stimulation parameters associated with the electrodes. The programmed stimulation parameter set is compared with sets of reference stimulation parameters, each of the reference sets of stimulation parameters being associated with the electrodes. If an identical match is determined between the programmed stimulation parameter set and any one of the reference stimulation parameter sets exists based on the comparison, the identically matched stimulation parameter set is selected as an initial stimulation parameter set. If an identical match does not exist, a best between the programmed stimulation parameter set and the reference stimulation parameter sets is determined and selected as the initial stimulation parameter set.

  • Patent number: 9731133
    Abstract: Methods for systematically testing a plurality of therapy programs in a spinal cord modulation system, and associated systems are disclosed. A representative method comprises loading a plurality of therapy programs into a signal generator, wherein individual therapy programs include parameters specifying electrode configuration, signal amplitude, and/or signal frequency. The programs are automatically activated for an automatically instructed period of time. The method includes automatically changing from one therapy program to another after the instructed period of time. The patient is queried for patient input corresponding to the therapy programs. The patient input is received via a remote. The patient input is correlated with a corresponding time of day and recorded in the signal generator. Thereafter, the patient input is retrieved from the signal generator.
