  • Publication number: 20170056627
    Abstract: An introducer set includes an introducer and dilator along with an extension in a sealed sterile peal open package. The extension is available for use during procedures where the puncture access site to the patient is close enough to the site to be treated in the patient that the physician's hands and/or head may be positioned in the fluroscopic area while the physician is attempting to maneuver a wire guide to a desired location. When the extension is attached to the introducer, the physician may perform a procedure, such as an antigrade stick in the lower leg of a patient, while maintaining their hands and head outside of the fluroscopic area while direct radiation is being supplied and the wire guide is being maneuvered to a desired treatment location.

    Abstract: Methods and devices for configuring the use of a motion sensor in an implantable cardiac device. The electrical signals of the patient's heart are observed and may be correlated to the physical motion of the heart as detected by the motion sensor of the implantable cardiac device in order to facilitate temporal configuration of motion sensor data collection that avoids detecting cardiac motion in favor of overall motion of the patient.

  • Publication number: 20170056666
    Abstract: Implantable devices having motion sensors. In some examples the a configuration is generated for the implantable device to use the motion sensor in an energy preserving mode in which one or more axis of detection of the motion sensor is disabled or ignored. In some examples the motion sensor outputs along multiple axes are analyzed to determine which axes best correspond to certain patient parameters including patient motion/activity and/or cardiac contractility. In other examples the output of the motion sensor is observed across patient movements or postures to develop conversion parameters to determine a patient standard frame of reference relative to outputs of the motion sensor of an implanted device.

  • Publication number: 20170056667
    Abstract: Systems, devices, and methods for determining occurrences of myocardial infarctions are disclosed. In one embodiment, a method of sensing for an occurrence of a myocardial infarction may include sensing a baseline accelerometer signal during a baseline, determining a baseline template based on one or more characteristics of the baseline accelerometer signal, and storing the baseline template in a memory. The method may further include sensing an accelerometer signal during a test period subsequent to the baseline, determining a test template based on one or more characteristics of the accelerometer signal during the test period, and comparing the baseline template with the test template, and based on the comparison, determining if a myocardial infarction occurred in the patient's heart. If it is determined that a myocardial infarction occurred in the patient's heart, the method may further include displaying an indication on a display that a myocardial infarction occurred.

  • Publication number: 20170056668
    Abstract: A leadless cardiac pacemaker includes a housing and two or more electrodes secured relative to the housing. A controller is configured to receive electrical signals from the two or more electrodes indicative of a heartbeat of the patient's heart and determine a first measure of cardiac load based at least in part on a delay between the Q or R feature and the T feature for the heartbeat. An accelerometer is configured to sense an activity level of the patient and the controller is configured to determine a second measure of cardiac load based at least in part on the activity level of the patient. A pacing rate is based at least in part upon the first measure of cardiac load, with the second measure of cardiac load used as a governor to the determined pacing rate.

  • Publication number: 20170056669
    Abstract: Systems, devices, and methods for pacing a heart of a patient are disclosed. In some embodiments, a method for pacing a patient's heart may include determining a posture of the patient and determining if the determined posture corresponds to a predetermined sleep posture. If the determined posture correspond to the predetermined sleep posture, the method may further comprise determining a respiration phase of the patient and pacing the patient's heart at a pacing rate that is modulated based on the determined respiration phase of the patient. If the determined posture does not correspond to the predetermined sleep posture, the method may pace the patient's heart at a pacing rate that is not dependent on the respiration phase of the patient.

  • Publication number: 20170056670
    Abstract: In some examples, a leadless pacing device (hereinafter, “LPD”) is configured for implantation in a ventricle of a heart of a patient, and is configured to switch between an atrio-ventricular synchronous pacing mode and an asynchronous ventricular pacing mode in response to detection of one or more sensing events, which may be, for example, undersensing events. In some examples, an LPD is configured to switch from a sensing without pacing mode to an atrio-ventricular synchronous pacing mode in response to determining, for a threshold number of cardiac cycles, a ventricular depolarization was not detected within a ventricular event detection window that begins at an atrial activation event.

  • Publication number: 20170056672
    Abstract: The disclosure relates to systems and methods for cardiac rhythm management. In some cases, a system may include a pulse generator for generating pacing pulses for stimulating a heart of a patient; a memory; and a sensor configured to sense a response to an unwanted stimulation and to produce a corresponding sensor signal. A processing circuit may receive the sensor signal for a time after one or more pacing pulses, and may derive a time-frequency representation of the sensor signal based on the received sensor signal. The processing circuit may use the time-frequency representation of the sensor signal to help identify unwanted stimulation. Once unwanted stimulation is detected, the processing circuit may change the pacing pulses to help reduce or eliminate the unwanted stimulation.

  • Publication number: 20170056676
    Abstract: A system for providing neurostimulation includes an external device (“external exciter”) and an implanted device. The external exciter includes an energy source which inductively powers the implanted device. Examples of such external exciters include devices having at least one of: ultrasonic transducers, Radio Frequency (RF) transmitters, and solar cells. The implanted device includes circuitry that limits its maximum energy output to a predetermined saturation threshold such that excess stimulation from the external exciter does not raise the output of the implanted device beyond the saturation threshold. The output signal of the external exciter is then pulse-width modulated in order to produce a desired amount of output stimulation from the implanted device to stimulate the bioelectrically excitable tissue at a desired level.
