  • Patent number: 10933238
    Abstract: A power control circuit for use with devices that will be placed in a flammable sterilizing gas includes a bi-stable switch that is configured to produce an output to place the circuitry of a connected device in a run state or a sleep state. The bi-stable switch controls one or more transistors to drain energy from energy storage devices in the circuitry of the connected device to a level below an ignition level of a sterilizing gas. A remotely actuatable switch can be actuated from outside of a packaging in which the power control circuit is placed to cause the bi-stable switch to produce an output that puts the circuitry in the run state without removing the power control circuit from the packaging.

  • Patent number: 10780276
    Abstract: Systems and methods for selecting low-power, effective signal delivery parameters for an implanted pulse generator are disclosed. A representative system includes a signal generator and a computer-readable medium that, for first and second signals, increases and decreases an amplitude of the signal over multiple steps from a baseline amplitude at which the patient has a baseline response. At individual step increases and decreases, the system receives a pain score based on the patient's response. The instructions compare the pain scores for the two signals and determine one of the signals for additional therapy to the patient, based on the pain scores and an expected energy consumption of the signals.

  • Patent number: 10682516
    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.
