  • Patent number: 10022551
    Abstract: A wearable defibrillator system includes a support structure with one or more electrodes in an unbiased state. A monitoring device monitors, for the long term, a parameter of the person that is not the person's ECG; rather, the monitored parameter can be the person's motion, a physiological parameter, or both. When a value of the monitored parameter reaches a threshold, such as when the person is having an actionable episode, the electrode becomes mechanically biased against the person's body, for making good electrical contact. Then, if necessary, the person can be given electrical therapy, such as defibrillation. As such, the electrodes of the wearable defibrillator system can be worn loosely for the long term, without making good electrical contact. This can reduce the person's aversion to wearing the defibrillation system.

  • Patent number: 9056207
    Abstract: At least two energy storage devices are used to realize biphasic defibrillation therapy. One of the energy storage devices is the primary energy storage device and the other (e.g. second) energy storage device is the auxiliary energy storage device. The first energy storage device is used to implement both the first and second phase pulses of biphasic pulse therapy to the patient, and the second energy storage device can be used to assist in the first and/or second phase pulse. In other words, the second energy storage device may be combined with the first energy storage device to discharge electricity to the patient to realize the first and/or second phase pulse.

  • Patent number: 9041551
    Abstract: A disclosed telemetry system comprises an Nth number of telemetry devices and an equal number of standard disposable circular electrode patches. A body of each telemetry device in the system includes a female snap receptor configured to attach to a single male snap post of an electrode patch. A wireless transmitter module is disposed immediately around and in direct connection with each female snap receptor. Each wireless transmitter module transmits a signal from the respective female snap receptor to a receiver. A wireless receiver module is configured to receive and to process an Nth number of transmitted signals from the Nth number of telemetry devices into an Nth?1 number of signals where the number of signals is greater than zero. There are Nth?1 number of signals because at least one of the Nth telemetry devices is configured as a ground reference for the rest of the Nth telemetry devices.

  • Publication number: 20150134021
    Abstract: Recent advancements in power electronics technology have provided opportunities for enhancements to circuits of implantable medical devices. The enhancements have contributed to increasing circuit miniaturization and an increased efficiency in the operation of the implantable medical devices. The therapy delivery circuits and techniques of the disclosure facilitate generation of a therapy stimulation waveform that may be shaped based on the patient's physiological response to the stimulation waveform. The generated therapy stimulation waveforms include a stepped leading-edge that may be shaped having a varying slope and varying amplitudes associated with each of the segments of the slope. Unlike the truncated exponential waveform delivered by the conventional therapy delivery circuit which is based on the behavior of the output capacitors (i.e., i=C(dV/dt)), the stimulation waveform of the present disclosure may be dynamically shaped as a function of an individual patient's response.

  • Patent number: 8996113
    Abstract: Systems and techniques that enable a user to selectively extend the time prior to providing an indication of power source depletion, e.g., allow an extended the recommended replacement time (RRT) prior to providing an elective replacement indication (ERI), are described. The user provides input, which may indicate an acceptable level of implantable medical device performance, e.g., that lesser performance for a period between a default RRT and an extended RRT is acceptable. In response to the input, the time until providing an RRT/ERI notification, or some other indication of depletion of the implantable medical device power source, may be extended.

  • Patent number: 8983604
    Abstract: Techniques are provided for controlling spinal cord stimulation (SCS) or other forms of neurostimulation. Far-field cardiac electrical signals are sensed using a lead of the SCS device and neurostimulation is selectively delivering using a set of adjustable SCS control parameters. Parameters representative of cardiac rhythm are derived from the far-field cardiac electrical signals. The parameters representative of cardiac rhythm are correlated with SCS control parameters to thereby map neurostimulation control settings to cardiac rhythm parameters. The delivery of further neurostimulation is then controlled based on the mapping of neurostimulation control settings to cardiac rhythm parameters to, for example, address any cardiovascular disorders detected based on the far-field cardiac signals. In this manner, a closed loop control system is provided to automatically adjust SCS control parameters to respond to changes in cardiac rhythm such as changes associated with ischemia, arrhythmia or heart failure.
