Abstract

A wearable therapeutic device includes a garment configured to be worn on a torso of a patient. The garment has an anterior portion and a posterior portion. The garment is configured to house at least one defibrillator component, a first therapy electrode disposed in the anterior portion of the garment, a second therapy electrode disposed in the posterior portion of the garment, and an alarm module configured to alert the patient of an impending defibrillation shock from the at least one defibrillator component to be delivered by at least one of the first therapy electrode and the second therapy electrode. The first therapy electrode and the second therapy electrode are configured to be electrically coupled to the at least one defibrillator component. At least one of the first therapy electrode and the second therapy electrode is at least one of woven into the garment and comprises a textile material.
