  • Patent number: 10974055
    Abstract: Circuitry useable to protect and reliably charge a rechargeable battery, even from a zero-volt state, is disclosed, and is particularly useful when employed in an implantable medical device. The circuit includes two charging paths, a first path for trickle charging the battery, and a second path for charging the battery at relatively higher currents. A passive diode is used in the first trickle-charging path which allows trickle charging even when the battery voltage is too low for reliable gating, while a gateable switch (preferably a PMOS transistor) is used in the second higher-current charging path when the voltage is higher and the switch can therefore be gated more reliably. A second diode between the two paths ensures no leakage to the substrate through the gateable switch during trickle charging. The load couples to the battery through the switch, and preferably through a second switch specifically used for decoupling the load.

  • Patent number: 10820864
    Abstract: An exemplary method includes determining a variability of a plurality of measurements of a cardiovascular parameter of a patient suffering from hypertension, the plurality of measurements recorded one at a time over a predetermined time period. The method further includes comparing the determined variability with a predetermined reference value. If the comparing indicates that the determined variability is less than the predetermined reference value, the method includes designating the patient to be within a first class of patients representative of patients that are likely to be responsive to subcutaneous neuromodulation therapy as a treatment for hypertension. If the comparing indicates that the determined variability is greater than the predetermined reference value, the method includes designating the patient to be within a second class of patients representative of patients that are likely to be unresponsive to subcutaneous neuromodulation therapy as a treatment for hypertension.

  • Publication number: 20200316381
    Abstract: A current generation architecture for an implantable stimulator device such as an Implantable Pulse Generator (IPG) is disclosed. Current source and sink circuitry are both divided into coarse and fine portions, which respectively can provide coarse and fine current resolutions to a specified electrode on the IPG. The coarse portion is distributed across all of the electrodes and so can source or sink current to any of the electrodes. The coarse portion is divided into a plurality of stages, each of which is capable via an associated switch bank of sourcing or sinking a coarse amount of current to or from any one of the electrodes on the device. The fine portion of the current generation circuit preferably includes source and sink circuitry dedicated to each of the electrode on the device, which can comprise digital-to-analog current converters (DACs).

  • Patent number: 10744318
    Abstract: Disclosed herein are current output architectures for implantable stimulator devices. Current source and sink circuitry is divided into a plurality of stages, each of which is capable via an associated switch bank of sourcing or sinking an amount of current to or from any one of the electrodes of the device. The current source circuitry is distinct from the current sink circuitry, and the two share no common circuit nodes prior to connection to the electrodes. In other words, the current source circuitry and the current sink circuitry do not share a common node other than the electrodes. Each stage is preferably formed of a current mirror for receiving a reference current and outputting a scaled version of current to that stage's switch bank. The scalar at each stage can be set by wiring a desired number of output transistors in parallel.
