  • Patent number: 10231673
    Abstract: A method for determining a stress level of a user based on a sympathovagal balance (SVB) value calculated based on a set of measurement data may include determining a heart-rate variability (HRV) characteristic as a ratio involving a number of autonomic nervous system (ANS) activity markers within a first portion of the set of measurement data and the number of ANS activity markers within a second portion of the set of measurement data, and then determining the stress level of the user based on the HRV characteristic. The first and second portions of the set of measurement data may be selected based on a user-specific baseline SVB value that divides a histogram representation of the set of measurement data into the first and second portions.

  • Patent number: 10195437
    Abstract: An implantable neurostimulator-implemented method for managing tachyarrhythmias through vagus nerve stimulation is provided. An implantable neurostimulator, including a pulse generator, is configured to deliver electrical therapeutic stimulation in a manner that results in creation and propagation (in both afferent and efferent directions) of action potentials within neuronal fibers of a patient's cervical vagus nerve. Operating modes of the pulse generator are stored. A maintenance dose of the electrical therapeutic stimulation is delivered to the vagus nerve via the pulse generator to restore cardiac autonomic balance through continuously-cycling, intermittent and periodic electrical pulses. A restorative dose of the electrical therapeutic stimulation is delivered to prevent initiation of or disrupt tachyarrhythmia through periodic electrical pulses delivered at higher intensity than the maintenance dose.

  • Patent number: 10188863
    Abstract: In some examples, a processor of a system evaluates a therapy program based on a score determined based on a volume of tissue expected to be activated (“VTA”) by therapy delivery according to the therapy program. The score may be determined using a three-dimensional (3D) grid comprising a plurality of voxels that are each assigned a value. The processor may register the VTA with the 3D grid and determine the score for the therapy program based on the values assigned to voxels with which the VTA overlaps. One or more therapy programs for electrical stimulation therapy (e.g., deep brain stimulation) may be selected based on the scores determined based on the 3D grid.

  • Patent number: 10159840
    Abstract: An active implantable medical device for neurostimulation therapy is disclosed. The device produces stimulation pulse sequences generated continuously in succession during activity periods separated by intermediate inactivity periods during which no stimulation is issued. An input signal, provided by a physiological sensor, representative of cardiac activity and/or of the patient's hemodynamic status is received by circuitry. The circuitry further provides for dynamic control of the neurostimulation therapy, wherein the length of activity periods is modulated based on the current value level of the control parameter compared to a threshold. The duration of the next period of inactivity is calculated by the circuitry at the end of each activity period to maintain a constant duty cycle ratio between periods of activity and periods of inactivity.

  • Patent number: 10124171
    Abstract: Via a user interface of an electronic device, virtual representations of an implantable pulse generator (IPG), an external pulse generator (EPG), and an implantable lead are displayed. A detection is made that the EPG has been selected. In response to the selection of the EPG, a first workflow is made automatically available. The first workflow is associated with using a Percutaneous Nerve Evaluation (PNE) needle to investigate an optimum location for implanting the implantable lead. A detection is made that the implantable lead has been coupled to the IPG or the EPG. In response to the coupling of the implantable lead to the IPG or the EPG, a second workflow is made automatically available. The second workflow is associated with evaluating a patient physiological response at least in part by using the implantable lead to deliver electrical stimulation to the patient.

  • Patent number: 10118043
    Abstract: A cochlear implant or other auditory prosthesis utilizes an external portion worn on a recipient's head and an internal portion implanted therein. Both portions include an associated coil that transmits a signal between the two portions. The external coil has a form factor substantially similar to the implantable coil. This form factor allows the external portion to be manufactured with a smaller footprint, since components that may otherwise interfere with signal transmission (e.g., batteries) may be installed closer to the external coil.

  • Patent number: 10117982
    Abstract: A system for improving heart muscle response during a pre-ejection phase in the heart muscle pumping cycle requires a catheter having a pressure transducer and a fluid device mounted at its distal end. Also included is a pump connected to the proximal end of the catheter in fluid communication with the fluid device. A computer will activate the pump in response to a predetermined signal from the pressure transducer to inject and maintain an increased fluid volume in the pumping chamber of the heart for a predetermined time interval ?t during the pre-ejection phase. This supplements the isometric pressure in the heart's pumping chamber in preparation for a subsequent ejection of blood from the pumping chamber.

  • Patent number: 10105542
    Abstract: A neurostimulation system having an external or an implantable pulse generator programmed to innervate a specific nerve or group of nerves in a patient through an electrode as a mode of treatment, having a patient remote that wirelessly communicates with the pulse generator to increase stimulation, decrease stimulation, and provide indications to a patient regarding the status of the neurostimulation system. The patient remote can allow for adjustment of stimulation power within a clinically effective range and for turning on and turning off the pulse generator. The patient remote and neurostimulation system can also store a stimulation level when the pulse generator is turned off and automatically restore the pulse generator to the stored stimulation level when the pulse generator is turned on.

  • Patent number: 10092743
    Abstract: Anchors for use with implantable medical leads include an elastic body containing one or more rigid bodies that have longitudinal free edges. The longitudinal free edges run from end to end to define full length slots. Partial length slots may also be included within the one or more rigid bodies. The full length and partial length slots allow for deflection of the rigid bodies against the body of an implantable medical lead to hold the anchor in place on the lead. The full length slots allow a blade to pass through and cut a slit in the elastic body which allows the anchor to be removed from the lead.
