Abstract: A wearable cardiac device for providing feedback during device assembly includes a garment configured to be continuously worn and an electrode belt including a plurality of assemblable elements. Each of the assemblable elements is configured for assembly into the garment prior to use of the wearable cardiac device. The plurality of assemblable elements includes electrodes configured to facilitate sensing electrical signals associated with cardiac activity of and/or deliver one or more therapeutic pulses to a patient. At least one of the plurality of assemblable elements includes respective local assembly feedback circuitry.

Abstract: A waterproof modular electrocardiogram (ECG) electrode assembly for use in a wearable cardiac monitoring device comprises a first, main circuit board comprising active ECG processing circuitry encapsulated in a waterproof moldable dielectric polymer, and an ECG electrode mechanically coupled to the waterproof moldable dielectric polymer, the ECG electrode configured to be electrically coupled to a portion of the main circuit board.

Abstract: A modular waterproof therapeutic electrode component for preventing water ingress and for easy servicing. The component comprises a substrate comprising a conductive surface, a reservoir of conductive fluid mounted on the substrate, a reusable waterproof enclosure comprising circuitry, the reusable waterproof enclosure comprising circuitry configured to be removably coupled to the substrate, and a fluid deployment device in electrical communication with the circuitry and mounted on the substrate, the fluid deployment device configured to cause the reservoir to release the conductive fluid onto the conductive surface to reduce electrical impedance between the conductive surface and skin of a subject.
