  • Patent number: 9452104
    Abstract: An Implantable ElectroAcupuncture Device (IEAD) treats cardiovascular disease through application of stimulation pulses applied at at least one of acupoints EX-HN1, BL14, HT7, HT5, PC6, ST36, LI11, LU7, and LU2. The IEAD comprises an implantable, coin-sized, self-contained, leadless electroacupuncture device having at least two electrodes attached to an outside surface of its housing. The device generates stimulation pulses in accordance with a specified stimulation regimen. Power management circuitry within the device allows a primary battery, having a high internal impedance, to be used to power the device. The stimulation regimen generates stimulation pulses during a stimulation session of duration T3 minutes applied every T4 minutes. The duty cycle, or ratio T3/T4 is very low, no greater than 0.05. The low duty cycle and careful power management allow the IEAD to perform its intended function for several years.

  • Patent number: 9440079
    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.

  • Publication number: 20160256115
    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.

  • Patent number: 9433786
    Abstract: An implantable electroacupuncture device (IEAD) treats Parkinson's disease or Essential Tremor through application of stimulation pulses applied at at least one of acupoints GB34 and GV20. The IEAD includes an hermetically-sealed implantable electroacupuncture (EA) device having at least two electrodes located outside of its housing. The housing contains a primary power source, pulse generation circuitry, and a sensor that wirelessly senses externally-generated operating commands. The pulse generation circuitry generates stimulation pulses as controlled, at least in part, by the operating commands sensed through the sensor. The stimulation pulses are applied to the specified acupoint or nerve through the electrodes in accordance with a specified stimulation regimen. Such stimulation regimen requires that the stimulation session be applied at a very low duty cycle not greater than 0.05.

  • Publication number: 20160250489
    Abstract: Tissue stimulation systems generally include a pulse generating device for generating electrical stimulation pulses, at least one implanted electrode for delivering the electrical stimulation pulses generated by the pulse generating device, and a programmer capable of communicating with the pulse generating device. Stimulation pulses may be defined by several parameters, such as pulse width and amplitude. In methods of stimulating the tissue with the stimulation system, a user may adjust one of the parameters such as pulse width. The programmer may automatically adjust the pulse amplitude in response to the change in pulse width in order to maintain a substantially constant effect of the stimulation pulses.

  • Publication number: 20160213929
    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).

  • Publication number: 20160213914
    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.

  • Patent number: 9375575
    Abstract: A method and neurostimulation system of providing therapy to a patient is provided. At least one electrode is placed in contact with tissue of a patient. A sub-threshold, hyperpolarizing, conditioning pre-pulse (e.g., an anodic pulse) is conveyed from the electrode(s) to render a first region of the tissue (e.g., dorsal root fibers) less excitable to stimulation, and a depolarizing stimulation pulse (e.g., a cathodic pulse) is conveyed from the electrode(s) to stimulate a second different region of the tissue (e.g., dorsal column fibers). The conditioning pre-pulse has a relatively short duration (e.g., less than 200 ?s).

  • Publication number: 20160158566
    Abstract: A method, computer medium, and system for programming a controller is provided. The controller controls electrical stimulation energy output to electrodes, and stores a set of programmed stimulation parameters associated with the electrodes. The programmed stimulation parameter set is compared with sets of reference stimulation parameters, each of the reference sets of stimulation parameters being associated with the electrodes. If an identical match is determined between the programmed stimulation parameter set and any one of the reference stimulation parameter sets exists based on the comparison, the identically matched stimulation parameter set is selected as an initial stimulation parameter set. If an identical match does not exist, a best between the programmed stimulation parameter set and the reference stimulation parameter sets is determined and selected as the initial stimulation parameter set.
