  • Patent number: 11925810
    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: 11911624
    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: 20240040649
    Abstract: An advertising algorithm is disclosed which operates in an Implantable Medical Device (IMD) to adjust an interval at which the IMD will transmit advertising data packets to an external device able to connect with the IMD. When a communication session between the IMD and an external device is terminated, the advertising algorithm will issue advertising data packets at a higher rate for a set duration. This will allow the external device to connect more quickly with the IMD in a next communication session. After the set duration, when it may be assumed that the external device is less likely to connect with the IMD, the algorithm reduces that rate at which advertising data packets are issued, which saves power in the IMD.

  • Patent number: 11801389
    Abstract: A neuromodulation customization system includes a field definition user interface, a neuromodulation signaling engine, and a supervisor engine. The field definition user interface is to facilitate entry of a customized electrotherapy field definition, with the field definition user interface including a set of input controls for defining field shape, field intensity, and field steering parameters of the customized electrotherapy field. The neuromodulation signaling engine is to produce commands for neuromodulation output circuitry to control generation of a customized electrotherapy field via a set of electrodes based on the customized electrotherapy field definition. The supervisor engine is to assess compliance of the customized electrotherapy field to be generated with applicable predefined criteria, and to modify generation of the customized electrotherapy field in response to an assessed non-compliance with the criteria.

  • Patent number: 11311726
    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: 20220096849
    Abstract: Systems and methods are disclosed for use with Implantable Medical Devices (IMD) such as Implantable Stimulator Devices. The system includes a permanent magnet which can be used to reset the IMD (such as during an emergency) and to place the IMD in a pairing mode to establish communications with an external device. An external device paired to the IMD can be used to place the IMD in an MRI mode that renders the IMD safe during a Magnetic Resonance Imaging (MRI) scan. In the event that the external device is unavailable to cause the IMD to exit the MRI mode, the bar magnet can also be used in the MRI mode to pair the IMD with another external device.

  • Patent number: 11266842
    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.
