  • Patent number: 11147977
    Abstract: An EMI/energy dissipating filter for an active implantable medical device (AIMD) is described. The filter comprises a first gold braze hermetically sealing the insulator to a ferrule that is configured to be mounted in an opening in a housing for the AIMD. A lead wire is hermetically sealed in a passageway through the insulator by a second gold braze. A circuit board substrate is disposed adjacent the insulator. A two-terminal chip capacitor disposed adjacent to the circuit board has an active metallization that is electrically connected to the active electrode plates and a ground metallization that is electrically connected to the ground electrode plates of the capacitor. A ground electrical path extends from the ground metallization of the chip capacitor to the ferrule. A conductive ground pin is electrically and mechanically connected to the ferrule. The ground path comprises an internal ground plate disposed within the circuit board substrate.

  • Patent number: 11147495
    Abstract: The present disclosure generally relates to systems and methods and systems of a noninvasive technique for characterizing cardiac chamber size and cardiac mechanical function. A mathematical analysis of three-dimensional (3D) high resolution data may be used to estimate chamber size and cardiac mechanical function. For example, high-resolution mammalian signals are analyzed across multiple leads, as 3D orthogonal (X,Y,Z), or 10-channel data, for 30 to 800 seconds, to derive estimates of cardiac chamber size and cardiac mechanical function. Multiple mathematical approaches may be used to analyze the dynamical and geometrical properties of the data.

  • Patent number: 11129538
    Abstract: Disclosed examples include heart rate monitor systems and methods to estimate a patient heart rate or rate of another pulsed signal, in which rate hypotheses or states, are identified for a current time window according to digital sample values of the pulsed signal for a current sample time window, and a rate change value is computed for potential rate transitions between states of the current and previous time windows. Transition pair branch metric values are computed as a function of the rate change value and a frequency domain amplitude of the corresponding rate hypothesis for the current time window, and the pulsed signal rate estimate is determined according to a maximum path metric computed according to the branch metric value and a corresponding path metric value for the previous time window.

  • Patent number: 11116564
    Abstract: Methods for treating anxiety disorders and for reducing a risk associated with developing an anxiety disorder in patients via therapeutic renal neuromodulation and associated systems are disclosed herein. Sympathetic nerve activity can contribute to several cellular and physiological conditions associated with anxiety disorders as well as an increased risk of developing an anxiety disorder. One aspect of the present technology is directed to methods for improving a patient's calculated risk score corresponding to an anxiety disorder status in the patient. Other aspects are directed to reducing a likelihood of developing an anxiety disorder in patients presenting one or more anxiety disorder risk factors. Renal sympathetic nerve activity can be attenuated to improve a patient's anxiety disorder status or risk of developing an anxiety disorder. The attenuation can be achieved, for example, using an intravascularly positioned catheter carrying a therapeutic assembly configured to use, e.g.
