  • Publication number: 20210106834
    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.

  • Patent number: 10653885
    Abstract: A system for a neurostimulator coupled to electrodes, and a method of providing therapy to a patient using the electrodes implanted within the patient. A target multipole relative to the electrodes is defined. The target multipole is emulated by defining an initial electrical current distribution for the electrodes, such that a first set of active electrodes respectively has electrical current values of a first polarity. Each of the electrical current values of the first polarity is compared to a first threshold value, and at least one of the electrodes in the first active electrode set is zeroed-out based on the comparison. The electrical current value of each of the zeroed-out electrode(s) is redistributed to remaining ones of the electrodes to define a new electrical current distribution for the electrodes. Electrical current is conveyed to the electrodes in accordance with the new electrical current distribution, thereby providing the therapy.

  • 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.
