First Claim
1. A wearable defibrillator comprising:
- at least one sensing electrode configured to detect a marker signal received from a body of a patient wearing the wearable defibrillator;
at least one controller connected to the at least one sensing electrode; and
at least one response mechanism connected to the at least one controller, the at least one response mechanism configured to be actuated by the patient wearing the wearable defibrillator and to transmit the marker signal into the body of the patient wearing the wearable defibrillator during actuation of the at least one response mechanism;

Abstract
A medical device is disclosed that includes one or more treatment electrodes, one or more sensors, and one or more controllers connected to the one or more treatment electrodes and one or more sensors. The medical device also includes one or more response mechanisms connected to the one or more controllers. The one or more controllers are configured to receive input from the one or more response mechanism and are also configured to determine whether a patient wearing the medical device actuated the one or more response mechanisms based, at least in part, on the input received from the one or more response mechanisms. In some disclosed embodiments, the medical device is a wearable defibrillator.
