  • Publication number: 20190143107
    Abstract: The group of inventions relates to medicine (physiotherapy). Electric stimuli which are generated by the following ringing circuit: active electrode-inductive storage unit-passive electrode-interelectrode tissues-active electrode, contain oscillations which are used as a test signal. In one variant of the method the electrodes are successively applied (in another variant—moved uniformly) across the skin area. Every time the electrodes-to-skin contact is detected, the oscillation parameters are recorded after a delay. Moreover, the values of parameters can be averaged. The group of invention provides the use of both combined and disjointed (separated) electrodes. An optimal zone for electropulse therapy is identified by minimal or maximal value of one or more parameters of the aforementioned oscillations and the use of the principle of “small asymmetry”. The group of inventions provides an increase in the accuracy with which zones optimal for electropulse therapy are identified and localized.

  • Publication number: 20190143117
    Abstract: An implantable device and associated method for delivering multi-site pacing therapy is disclosed. The device comprises a set of electrodes including a first ventricular electrode and a second ventricular electrode, spatially separated from one another and all coupled to an implantable pulse generator. The device comprises a processor configured for selecting a first cathode and a first anode from the set of electrodes to form a first pacing vector at a first pacing site along a heart chamber and selecting a second cathode and a second anode from the set of electrodes to form a second pacing vector at a second pacing site along the same heart chamber. The pulse generator is configured to deliver first pacing pulses to the first pacing vector and delivering second pacing pulses to the second pacing vector. The pulse generator generates a recharging current for recharging a first coupling capacitor over a first recharge time period in response to the first pacing pulses.

  • Publication number: 20190143119
    Abstract: A variety of pathological behavioural and/or psychological states can be caused and/or characterized by changes in the degree of functional coupling between regions of the brain relative to a baseline degree of coupling. These pathological behavioural and/or psychological states may include bipolar disorder, mood disorders, PTSD, anxiety disorders, schizophrenia, or autism. Such changes may be caused by experiences and/or genetic factors. To treat such pathological behaviour and/or psychological states, the degree of functional coupling between particular regions of the brain may be increased. An increase in the functional coupling between first and second brain regions may be caused by providing repeated excitatory stimuli to the first brain region in phase with oscillatory patterns of activity in the second brain region.

  • Publication number: 20190143121
    Abstract: A system for use with a neurostimulator coupled to one or more electrodes implanted adjacent neural tissue of a patient. The system comprises a user input device configured for allowing a user to select different nerve fiber diameters and to select a set of stimulation parameters. The system further comprises processing circuitry configured estimating regions of activation within the neural tissue of the patient based on the selected nerve fiber diameters and the selected stimulation parameter set. The system further comprises a display device configured for displaying the estimated regions of tissue activation. The user input device may further be configured for allowing the user to select different tissue regions of therapy, in which case, the display device may display the different tissue region on a human body map, and different indicia associating the displayed tissue regions for therapy to displayed estimated regions of tissue activation.

  • Publication number: 20190143122
    Abstract: Approaches to rank potential left ventricular (LV) pacing vectors are described. Early elimination tests are performed to determine the viability of LV cathode electrodes. Some LV cathodes are eliminated from further testing based on the early elimination tests. LV cathodes identified as viable cathodes are tested further. Viable LV cathode electrodes are tested for hemodynamic efficacy. Cardiac capture and phrenic nerve activation thresholds are then measured for potential LV pacing vectors comprising a viable LV cathode electrode and an anode electrode. The potential LV pacing vectors are ranked based on one or more of the hemodynamic efficacy of the LV cathodes, the cardiac capture thresholds, and the phrenic nerve activation thresholds.

  • Publication number: 20190143123
    Abstract: Implantable medical devices include connector enclosure assemblies that utilize conductors that are electrically coupled to feedthrough pins and that extend into a can where electrical circuitry is housed. The conductors may be coupled to the feedthrough pins and to capacitor plates within a filter capacitor by an electrically conductive bonding material and as a single bonding event during manufacturing. The base plate of the connector enclosure assembly may also include a ground pin. Ground capacitor plates may be present at a ground aperture of the filter capacitor where the ground pin passes through so that the ground pin, a ground conductor, and the ground capacitor plate may be coupled. A protective cover may be provided for the connector enclosure assembly to enclose the conductors intended to extend into the can prior to the assembly being joined to the can. Conductors may be attached to a common tab that is subsequently removed.
