Publication number: 20170056669Abstract: 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.Type: ApplicationFiled: August 26, 2016Publication date: March 2, 2017Applicant: Cardiac Pacemakers, Inc.Inventors: Michael J. Kane, Allan Charles Shuros, Paul Huelskamp, Benjamin J. Haasl, Keith R. Maile

Publication number: 20170056670Abstract: 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.Type: ApplicationFiled: November 14, 2016Publication date: March 2, 2017Inventors: Todd J.

Publication number: 20170056671Abstract: Systems, methods, and devices for determining occurrences of a tamponade condition are disclosed. One exemplary method includes monitoring an accelerometer signal of a leadless cardiac pacemaker attached to a heart wall, determining if a tamponade condition of the patient's heart is indicated based at least in part on the monitored accelerometer signal, and in response to determining that the tamponade condition is indicated, providing a notification of the tamponade condition for use by a physician to take corrective action.Type: ApplicationFiled: August 23, 2016Publication date: March 2, 2017Applicant: Cardiac Pacemakers, Inc.Inventors: Michael J.

Publication number: 20170056672Abstract: 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.Type: ApplicationFiled: November 10, 2016Publication date: March 2, 2017Inventors: Holly E. Rockweiler, David C. Olson, Sunipa Saha

Publication number: 20170056676Abstract: 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.Type: ApplicationFiled: August 2, 2016Publication date: March 2, 2017Applicant: Arizona Board of Regents on behalf of Arizona State UniversityInventors: Bruce C.
