Abstract: Wearable devices are provided herein including wearable defibrillators, wearable devices for diagnosing symptoms associated with sleep apnea, and wearable devices for diagnosing symptoms associated with heart failure. The wearable external defibrillators can include a plurality of ECG sensing electrodes and a first defibrillator electrode pad and a second defibrillator electrode pad. The ECG sensing electrodes and the defibrillator electrode pads are configured for long term wear. Methods are also provided for using the wearable external defibrillators to analyze cardiac signals of the wearer and to provide an electrical shock if a treatable arrhythmia is detected. Methods are also disclosed for refurbishing wearable defibrillators. Methods of using wearable devices for diagnosing symptoms associated with sleep apnea and for diagnosing symptoms associated with heart failure are also provided.

Abstract: Embodiments of a wearable device are provided. The wearable device comprises a reusable component and a disposable component. The disposable component comprises a patient engagement substrate comprising adhesive on a bottom side, an electrode on the bottom side, a disposable component electrical connector, and a disposable component mechanical connector. The reusable component comprises a plurality of sealed housings mechanically coupled to each other and movable with respect to each other, each of the plurality of housings containing one or more of a capacitor and a controller, a reusable component mechanical connector adapted to removably connect to the disposable component mechanical connector, and a reusable component electrical connector adapted to removably connect to the disposable component electrical connector. The device can comprise a cardiopulmonary physiologic monitor or an automatic external defibrillator, among other types of devices.
