1. A serviceable wearable cardiac treatment device for continuous extended use by an ambulatory patient, comprising:
a garment configured to dispose therein a plurality of ECG sensing and therapy electrodes configured to be in continuous extended contact with the patient to monitor for and treat a cardiac arrhythmia in the patient; and
a device controller configured to be in separable electrical communication with the plurality of ECG sensing and therapy electrodes in the garment, the device controller comprising
an impact-resistant energy core, comprising
a frame, and
at least one capacitor permanently bonded to the frame such that the frame along with the bonded at least one capacitor comprise a unitary mass, the at least one capacitor configured to hold electrical charge sufficient to treat the cardiac arrhythmia,
first and second circuit boards comprising cardiac arrhythmia monitoring and therapy circuitry in electrical communication with the at least one capacitor, the first and second circuit boards being affixed to opposing sides of the impact-resistant energy core in a manner to allow for separation from the impact-resistant energy core during service, and
an ingress-protective housing configured to enable removal of the impact-resistant energy core and the first and second circuit boards during service, wherein the ingress-protective housing comprises
at least two shells configured to mate in a sealed configuration, the at least two shells configured to receive the impact-resistant energy core and the affixed first and second circuit boards therein,
wherein one or more of the at least two shells comprises at least one shock absorbing spacer disposed therein, the at least one shock absorbing spacer positioned to support the impact-resistant energy core and the affixed first and second circuit boards within the ingress-protective housing such that, upon impact, the impact resistant energy core and the affixed first and second circuit boards deform into the at least one shock absorbing spacer and the first and second circuit boards are prevented from flexing, thereby protecting the impact-resistant energy core and the affixed first and second circuit boards from mechanical impact.
