  • Patent number: 9993644
    Abstract: An exemplary fitting system 1) directs an EAS system to concurrently apply acoustic stimulation to a patient by way of a loudspeaker and electrical stimulation to the patient by way of an electrode located within a cochlea of the patient, 2) determines an interactive effect that the electrical stimulation has on the acoustic stimulation, 3) directs, if the fitting facility determines that the interactive effect is suppressive, the EAS system to use a first stimulation strategy that steers a current field produced by stimulation of the electrode away from intracochlear acoustic responders within the patient that are associated with the acoustic stimulation, and 4) directs, if the fitting facility does not determine that the interactive effect is suppressive, the EAS system to use a second stimulation strategy that steers the current field produced by the stimulation of the electrode towards the intracochlear acoustic responders.

  • Patent number: 9956402
    Abstract: Radiopaque markers represent that a lead is suitable for a particular medical procedure such as a magnetic resonance image scan and are added to the lead or related device. The markers may be added after implantation of the lead in various ways including suturing, gluing, crimping, or clamping a radiopaque tag to the lead or to the device. The markers may be added by placing a radiopaque coil about the lead, and the radiopaque coil may radially contract against the lead to obtain a fixed position. The markers may be added by placing a polymer structure onto the lead where the polymer structure includes a radiopaque marker within it. The polymer structure may include a cylindrical aperture that contracts against the lead to fix the position of the structure. The polymer structure may form a lead anchor that includes suture wings that can be sutured to the lead.

  • Patent number: 9955891
    Abstract: Systems and methods are provided to detect subwaveforms of an ECG waveform. Electrical impulses are detected between at least one pair of electrodes of two or more electrodes placed proximate to a beating heart and are converted to an ECG waveform for each heartbeat of the beating heart using the detector. One or more subwaveforms within P, Q, R, S, T, U, and J waveforms of the ECG waveform for each heartbeat or in an interval between the P, Q, R, S, T, U, and J waveforms that represent the depolarization or repolarization of an anatomically distinct portion of muscle tissue of the beating heart are detected using a signal processor. A processed ECG waveform that includes the one or more subwaveforms for each heartbeat is produced using the signal processor. The processed ECG waveform is received from the signal processor is displayed using a display device.

    Abstract: A method of targeting fibrosis or autonomic nerve tissue for ablation in a subject is provided. The method includes performing at least one EGM analysis of a plurality of recorded atrial EGMs for a tissue in a region suspected of having fibrosis or autonomic nerve tissue. With regard to targeting fibrosis for ablation, the method includes determining one or more correlations of at least one AF EGM characteristic to a region having fibrosis from the plurality of recorded atrial EGMs for the tissue and determining whether the tissue contains dense fibrosis that would preclude effective ablation of the analysis region of the tissue. With regard to targeting autonomic nerve for ablation, the method includes determining whether one or more significant changes in EGM characteristics with autonomic blockade exist that would indicate the need to perform ablation of the analysis region of the tissue.

  • Patent number: 9956417
    Abstract: A technique for identifying lead-related conditions, such as insulation breaches and/or externalization of lead conductors, includes analyzing characteristics of electrical signals generated on one or more electrode sensing vectors of the lead by a test signal to determine whether a lead-related condition exists. The characteristics of the electrical signals induced on the lead by the test signal may be significantly different on a lead having an insulation breach or externalized conductor than on a lead not having such lead-related conditions. As such, the implantable medical device may be subject to a known test signal and analyze the signals on the lead to detect lead-related conditions.

  • Patent number: 9936920
    Abstract: Self measurements of physiological parameters such as blood pressure are prone to errors and artifacts since they are often not done according to established and standardized protocols i.e., such that predetermined conditions for a reliable measurement are not met. To determine whether the predetermined conditions for a reliable measurement are met one or more physiological and environmental sensors are used to determine a measurement context. The obtained sensor data is compared with predetermined thresholds to determine whether the context allows a reliable self test. In case the predetermined conditions are not met based on the obtained sensor data instructions are given to guide the subject that wants to do a self test.
