  • Patent number: 11020595
    Abstract: Systems and methods for treating cardiac arrhythmias are disclosed. In one embodiment, an SICD comprises two or more electrodes, a charge storage device, and a controller operatively coupled to two or more of the electrodes and the charge storage device. In some embodiments, the controller is configured to monitor cardiac activity of the heart of the patient, detect an occurrence of a cardiac arrhythmia based on the cardiac activity, and determine a type of the detected cardiac arrhythmia from two or more types of cardiac arrhythmias. If the determined type of cardiac arrhythmia is one of a first set of cardiac arrhythmia types, the controller sends an instruction for reception by an LCP to initiate the application of ATP therapy by the LCP. If the determined type of cardiac arrhythmia is not one of the first set cardiac arrhythmia types, the controller does not send the instruction.

  • Patent number: 10806931
    Abstract: Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include a tubular member and a distal holding section extending distally of a distal end of the tubular member and defining a cavity therein for receiving an implantable leadless pacing device. The delivery device may facilitate vascular delivery of the pacing device to a left side of a patient's heart. In one example, a distal tip portion may extend distal of the distal holding section and may be actuated between a closed and an opened position. When in the closed position, the distal tip portion may have a tip that can puncture or engage an opening in a septum between a left atrium and a right atrium of a patient's heart. Actuating the distal tip portion to an opened position may be utilized to dilate the puncture or opening in the septum.
