Water resistant wearable medical device

A wearable medical device, comprising:

• a water-resistant harness to be worn by a patient;
• a plurality of ECG sensing electrodes disposed on the water-resistant harness and configured to sense an ECG signal of the patient;
• a plurality of therapy electrodes additionally disposed on the water-resistant harness and configured to provide at least one defibrillating biphasic shock to the patient, a first phase of the at least one defibrillating biphasic shock with a first therapy electrode with a second therapy electrode acting as a return, and a second phase of the at least one defibrillating biphasic shock with the second therapy electrode with the first therapy electrode acting as the return,
• wherein the water-resistant harness is configured to dispose the first therapy electrode and the second therapy electrode on opposite sides of the patient's torso;
• a control unit, electrically coupled to the plurality of ECG sensing electrodes and the plurality of therapy electrodes and configured to
• monitor ECG information of the patient based on the sensed ECG signal, and
• responsive to detection of a cardiac arrhythmia in the ECG information of the patient, provide the at least one defibrillating biphasic shock, wherein the control unit is comprised within a waterproof case;
• and
• a water-resistant or waterproof connection pod configured to electrically couple to the plurality of ECG sensing electrodes, the plurality of therapy electrodes, and the control unit, wherein the connection pod provides the sensed ECG signal from the plurality of ECG sensing electrodes as the ECG information to the control unit and the at least one defibrillating biphasic shock from the control unit to the plurality of therapy electrodes.
