Abstract: A lead body having a defibrillation electrode positioned along a distal portion of the lead body is described. The defibrillation electrode includes a plurality of electrode segments spaced a distance apart from each other. At least one of the plurality of defibrillation electrode segments includes at least one coated portion and at least one uncoated portion. The at least one coated portion is coated with an electrically insulating material configured to prevent transmission of a low voltage signal (e.g., a pacing pulse) while allowing transmission of a high voltage signal (e.g., a cardioversion defibrillation shock). The at least one uncoated portion is configured to transmit both low voltage and high voltage signals. The lead may also include one or more discrete electrodes proximal, distal or between the defibrillation electrode segments.

Abstract: An extra-cardiovascular medical device is configured to select a capacitor configuration from a capacitor array and deliver a low voltage, pacing pulse by discharging the selected capacitor configuration across an extra-cardiovascular pacing electrode vector. In some examples, the medical device is configured to determine the capacitor configuration based on a measured impedance of the extra-cardiovascular pacing electrode vector.

Abstract: A tool for inserting an elongate medical device into a body includes a track (e.g. defined by inner surfaces of a base wall and opposing sidewalls), and a deployment assembly for moving the device along the track. A retainer of the assembly, fitted in sliding engagement within the track and limited to move only along a portion of the track, grips a first portion of a proximal length of the device; a slider of the assembly, also fitted in sliding engagement within the track and detachably joined to the retainer, receives a second portion of the device proximal length. When detached from the retainer, the slider is free to move along a distal length of the device, and can be moved along a distal segment of the track to disengage therefrom by separating from a distal terminal end of the guide.
