  • Publication number: 20200016409
    Abstract: An example of a neurostimulation system may include a storage device, a programming control circuit, and a graphical user interface (GUI). The storage device may be configured to store individually definable waveforms. The programming control circuit may be configured to generate stimulation parameters controlling the delivery of the neurostimulation pulses according to a pattern. The GUI may be configured to define the pattern using one or more waveforms selected from the individually definable waveforms. The GUI may display waveform tags each selectable for access to a waveform of the individually definable waveforms, and display a waveform builder in response to selection of one of the waveform tags. The waveform builder may present a graphical representation of the accessed waveform and allow for the accessed waveform to be adjusted by editing the graphical representation of the accessed waveform on the GUI.

  • Publication number: 20190366104
    Abstract: An implantable stimulator device is disclosed for executing a stimulation program comprising a plurality of sub-programs, wherein the sub-programs are configured to be automatically sequentially executed by stimulation circuitry in the device. Control circuitry periodically stores log data to indicate where each sub-program is in its execution. If the device experiences an interruption that prevents the stimulation circuitry from executing the stimulation program, and upon receiving an indication that the stimulation circuitry can continue execution of the stimulation program, the control circuitry is configured to query the log data to determine a sub-program during which the interruption occurred, and using the log data, cause the stimulation circuitry to continue execution of the stimulation circuitry either at the beginning of the sub-program, or at a point during the sub-program when the interruption occurred.

  • Publication number: 20190344087
    Abstract: Systems and methods are disclosed in which an external device such as a consumer mobile device (e.g., smart phone) is used as an external controller to bi-directionally communicate with an Implantable Medical Device (IMD) using a dedicated patient remote control (RC) as an intermediary device to translate communications between the two. The dedicated RC contains a graphical user interface allowing for control and monitoring of the IMD even if the mobile device is not present in the system, which is useful as a back-up should the mobile device experience problems. Use of the dedicated RC as an intermediary device broadens the utility of other computing devices to operate as an external controller for an IMD even if the computing device and IMD do not have compliant communication means.

Transitions between anodic and cathodic modes of stimulation can include linear or user-customized adjustments of stimulation parameters of the anodic and cathodic modes during a transition period. Continuous interleaving of anodic and cathodic modes of stimulation can include repeating, continuous adjustments of stimulation parameters of the anodic and cathodic modes according to user-customized parameters and user-defined time apportionments. Interfaces additionally provide information regarding the relative energy usages of the different stimulation modes and visualizations of the effects of adjustments of the stimulation modes on energy usage.

  • Publication number: 20190290914
    Abstract: An electrical stimulation system includes a control module that provides electrical stimulation signals to an electrical stimulation lead coupled to the control module for stimulation of patient tissue. The system also includes a sensor to be disposed on or within the body of the patient and to measure a biosignal; and a processor to communicate with the sensor to receive the biosignal and to generate an adjustment to one or more of the stimulation parameters based on the biosignal. The adjustment can be configured and arranged to steer the electrical stimulation signals to stimulate a region of the patient tissue that is different, at least in part, from a region of the patient tissue stimulated prior to the adjustment. Alternatively or additionally, the biosignal is indicative of a particular patient activity and the adjustment is a pre-determined adjustment selected for the particular patient activity.

  • Publication number: 20190209851
    Abstract: A filtering algorithm implemented by a filtering module in an implantable medical device (IMD), or in an external device for communicating with an IMD, is disclosed which reviews blocks based on a number of rules. The filtering module preferably comprises both firewall and instruction analysis modules. The instruction analysis module analyzes the instructions and associated data (if present) in each block to determine whether such blocks would compromise operation of the IPG or injure a patient if executed. Instruction rules corresponding to an instruction identified in the block are retrieved by the instruction analysis module. The instruction analysis module reviews the block per the retrieved rules, and possibly also in light of current and historical IPG therapy setting or mode data, or other received but un-executed blocks. If a block is compliant, it is executed by the IMD or transmitted to the IMD.

  • Publication number: 20190184168
    Abstract: An external control device, neuromodulation system, and method of providing therapy to a patient using an implantable neuromodulator implanted within the patient. Electrical modulation energy is delivered from the neuromodulator to the patient in accordance with the pre-existing modulation program when in one of the super-threshold delivery mode and the sub-threshold delivery mode. Operation of the neuromodulator is switched to the other of the super-threshold delivery mode and the sub-threshold delivery mode. A new modulation program may be derived from a pre-existing modulation program, and the neuromodulator may deliver the electrical modulation energy to the patient in accordance with the pre-existing modulation program during the other of the super-threshold delivery mode and the sub-threshold delivery mode.

  • Publication number: 20190184167
    Abstract: An external control device and method for programming an implantable neuromodulator coupled to an electrode array implanted adjacent tissue of a patient having a medical condition. Electrical modulation energy is conveyed to tissue of the patient in accordance with a series of modulation parameter sets. The patient perceives paresthesia in response to the conveyance of the electrical modulation energy to the tissue in accordance with at least one of the modulation parameter sets. One of the modulation parameter set(s) is identified based on the perceived paresthesia. Another modulation parameter set is derived from the identified modulation parameter set. Electrical modulation energy is conveyed to the tissue of the patient in accordance with the other modulation parameter set without causing the patient to perceive paresthesia.
