  • Patent number: 10272251
    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: 10232181
    Abstract: A neurostimulation system comprises at least one neurostimulation lead configured for being implanted within tissue. The neurostimulation lead(s) carries a plurality of electrodes capable of being arranged in a two-dimensional pattern. The neurostimulation system further comprises a neurostimulator configured for delivering electrical stimulation energy to the electrodes to create a volume of activation, and an external control device including a current steering direction control element capable of being rotated about an axis. The external control device is configured for prompting the neurostimulator to deliver the electrical stimulation energy to the electrodes in a manner that gradually translates the volume of activation in a specific direction, and for defining the specific direction in which the volume of activation is translated in response to rotation of the direction control element about the axis.

    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.

  • Patent number: 10029102
    Abstract: A neuromodulation system and method of providing therapy to a patient. Electrical energy is delivered to the patient in accordance with a modulation parameter, thereby providing therapy to the patient, and the modulation parameter of the delivered electrical energy is varied over a period of time, such that the delivered electrical energy is continually maintained at a sub-threshold level throughout the period of time. The sub-threshold level may be referred to as a patient-perception threshold, which may be referred to as a boundary below which a patient does not sense delivery of the electrical energy. For example, in a spinal cord modulation system, the patient-perception threshold may be a boundary below which a patient does not experience paresthesia.

  • Publication number: 20180147413
    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.

  • Patent number: 9950172
    Abstract: A neurostimulation system for management of stimulation safety limits. The system determines a tissue charge injection metric at each electrode, compares the metric to the hard stop charge limit, and prevents the neurostimulator from delivering stimulation energy to the tissue region in accordance based on the comparison. The hard stop limit may be user-programmable or may be automatically modified in response to detection of electrode characteristics. The system may quantitatively notify a user of a value of the injected charge injected into the tissue. The electrodes may be organized into different sets, in which case, the system may directly control tissue charge independently at each of the electrode sets. If current steering is provided, the system may displace the electrical stimulation energy along the tissue region in one direction, while preventing the charge injection value at each of the electrodes from meeting or exceeding the hard stop charge limit.
