  • Patent number: 11304794
    Abstract: The techniques of this disclosure generally relate to modular stent device and method of deploying the same. The method includes introducing a delivery system including the modular stent device via supra aortic access. The delivery system is advanced into the ascending aorta. Once positioned, the modular stent device is deployed from the delivery system such that an artery leg of the modular stent device engages the brachiocephalic artery and a bypass gate engages the aorta, wherein the artery leg partially collapses the bypass gate. The artery leg has a greater radial force than the bypass gate such that the artery leg remains un-collapsed and opened. Accordingly, blood flow through the artery leg and perfusion of the brachiocephalic artery and preservation of blood flow to cerebral territories including the brain is insured.

The system includes for delivering cardiac pacing pulses to a patient's heart coupled to a cardiac sensing module and a cardiac pacing module for generating cardiac pacing pulses and controlling delivery of the pacing pulses at multiple pace parameter settings. An acoustical sensor obtains heart sound signals. A processor is enabled to receive the heart sound signals, derive a plurality of heart sound signal parameters from the heart sound signals, and determine a trend of each of the plurality of heart sound signal parameters with respect to the plurality of pace parameter settings. An external display is configured to present the trend of at least one heart sound parameter with respect to the plurality of pace parameter settings.

  • Patent number: 11308783
    Abstract: A medical device is configured to produce an accelerometer signal and detect a patient fall from the accelerometer signal. The device generates a body posture signal and a body acceleration signal from the accelerometer signal and detects a patient fall in response to determining that the body posture signal and the body acceleration signal meet fall detection criteria. The medical device is configured to receive a truth signal from another device that is not the medical device. The truth signal may indicate that the detected patient fall is a falsely detected patient fall and, responsive to receiving the truth signal, the medical device adjusts at least one fall detection control parameter.

  • Patent number: 11298548
    Abstract: In some examples, controlling delivery of CRT includes controlling an implantable medical device to deliver ventricular pacing according to a sequence of different values of a CRT parameter, and acquiring first and second electrograms from respective first and second electrode vectors. For each value of the CRT parameter, a value of a metric of comparison of a first activation interval between occurrences of a first fiducial of a cardiac cycle and a second fiducial of the cardiac cycle detected in the first electrogram to a second activation interval between occurrences of the first fiducial and the second fiducial detected in the second electrogram may be determined. A target value of the metric of comparison may be identified and an updated value of the CRT parameter determined based on the target value. The system then may control the IMD to deliver ventricular pacing at the updated value of the CRT parameter.
