    Abstract: Systems and methods for detecting cardiac arrhythmia are discussed. An exemplary arrhythmia detection system can receive physiologic information of the patient, measure a first signal metric using a first portion of the received physiologic information, and determine an arrhythmia detection duration using a comparison between the measured first signal metric and a reference signal metric value. The system includes an arrhythmia detector to detect an AT episode using a second portion of the physiologic information corresponding to the determined arrhythmia detection duration.

    Abstract: Systems and methods are disclosed to an ambulatory medical device comprising a coil antenna, a transceiver circuit, and a control circuit. The transceiver circuit includes a receiver to detect a communication signal received by the coil antenna. The control circuit includes a timeout timer and is configured to set the receiver to an active mode, set the receiver to an inactive mode when the timeout timer expires after a first timeout duration and the communication signal is not detected by the receiver, maintain the receiver in the active mode when the communication signal is detected by the receiver before the timeout timer expires, decode a command in the communication signal to set the timeout timer to a second timeout duration, and set the receiver to the inactive mode when the timeout timer expires after the second timeout duration and the communication signal is not detected.

    Abstract: Systems and methods are disclosed to an ambulatory medical device. The ambulatory medical device comprising an activity sensor configured to produce an activity signal representative of activity level of a patient, a heart sound sensor configured to produce a heart sound signal, and a control circuit. The control circuit is configured to detect a change in activity level of the patient using the activity signal, enable monitoring of the heart sound signal in response to detecting the change in activity level, measure intensity of an S3 heart sound in the heart sound signal, and produce an indication of pulmonary hypertension (PH) when the measured intensity of the S3 heart sound exceeds a PH detection threshold intensity.

    Abstract: A tool for implanting a medical lead includes a body having distal region including a distal end, a proximal region including a proximal end, a central axis extending from the distal end to the proximal end, and a midpoint between the distal end and the proximal end. The distal region includes a rounded tip, and a distal lip surrounding a distal opening leading to a distal cavity dimensioned to receive and frictionally engage a connector component of the implantable lead. The proximal region includes a proximal lip surrounding a proximal opening leading to a proximal cavity. A chamber is located between the distal cavity and the proximal cavity. The tool includes a first window. A pair of resilient arms define at least a portion of the chamber and configured to frictionally engage a terminal pin of the implantable lead. The first window, chamber, and pair of resilient arms are located distal of the midpoint.

    Abstract: An implantable lead includes a tubular lead body having proximal end, a distal end opposite the proximal end. A distal assembly includes an outer shell having a proximal portion and a distal portion. A tubular inner preform is disposed at least partially within the outer shell and includes a longitudinal slot extending from the distal end toward the proximal end, and a circumferential slot extending partially around a circumference of the inner preform. A coupler is disposed within the shell and includes a channel extending distally from the proximal end and an intermediate portion between the proximal and distal portions. The inner preform is coupled to the proximal portion of the coupler. A helical electrode is disposed about the distal portion of the coupler and a distal portion extends from the distal portion of the shell. A first conductor is mechanically and electrically coupled to the coupler.

    Abstract: Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include a proximal section including a deflection mechanism for deflecting the proximal section, and a distal holding section extending distally of a distal end of the proximal section and defining a cavity therein for receiving an implantable leadless pacing device. The distal holding section may be structured to have portions that flex and bend while allowing the implantable device to be recaptured within the distal holding section.

    Abstract: Embodiments herein relate to implantable medical devices including a power subunit with a first biocompatible electrically conductive shell configured for direct contact with an in vivo environment. In some embodiments a lithium anode can be disposed within the first biocompatible electrically conductive shell in direct electrical communication with a feedthrough pin, wherein the feedthrough pin is electrically isolated from the first biocompatible electrically conductive shell. A cathode can also be disposed within the first biocompatible electrically conductive shell and can be in direct electrical communication with the first biocompatible electrically conductive shell. The first biocompatible electrically conductive shell has a positive electrical potential. The implantable medical device further includes an electronics control subunit with a control circuit disposed within a second biocompatible electrically conductive shell. Other embodiments are included herein.
