Abstract: A serviceable wearable cardiac treatment device for continuous extended use by an ambulatory patient includes a garment, a device controller, and an ingress-protective housing. The garment is configured to dispose therein a plurality of ECG sensing and therapy electrodes to monitor for and treat a cardiac arrhythmia in the patient. The device controller is configured to be in separable electrical communication with the plurality of ECG sensing and therapy electrodes and includes an impact-resistant energy core, and first and second circuit boards affixed to opposing sides of the impact-resistant energy core. The impact-resistant energy core includes a frame and at least one capacitor permanently bonded to the frame to form a unitary mass. The ingress-protective housing is configured to enable removal of the impact-resistant energy core and the first and second circuit boards during servicing.

Abstract: A system includes: at least one identification device associated with a wearable medical therapy device and configured to have information read therefrom and written thereto; at least one controller operatively connected to the at least one identification device and configured to at least one of retrieve the information from the at least one identification device and write the information to the at least one identification device; and at least one device positioned externally from the wearable medical therapy device and configured to interrogate the at least one identification device to at least one of obtain the information from the at least one identification device and write additional information to the at least one identification device.

Abstract: A case for a wearable medical device is provided. The wearable medical device includes internal circuitry enclosed within an external housing. The case includes a first part sized to surround a first portion of the external housing and a second part sized to surround a second portion of the external housing. The first part includes an inner surface with contours configured to receive corresponding contours of the external housing. The first part is connected to the second to form a parting line around the external housing. An assembly including a wearable medical device and an external case is also provided.

Abstract: A battery pack comprises: a body; a latching mechanism positioned at an upper corner of the body and configured to be placed in an extended position to grasp a portion of an upper edge of the battery well when the battery pack is positioned within the battery well and a depressed position to allow removal of the battery pack from the battery well. The battery pack is inserted into the battery well by orienting the bottom side of the body with a bottom edge of the battery well and rotating the battery pack into the battery well such that the latching mechanism engages the portion of the upper edge of the battery well to move the latching mechanism to the depressed position and continued rotation of the battery pack allows the latching mechanism to return to the extended position to grasp the portion of the upper edge of the battery well.

Abstract: A defibrillator includes: a housing; a discharge module disposed on a first portion of a printed circuit board and positioned within the housing; an energy storage module disposed on a second portion of the printed circuit board; and a controller module disposed on a third portion of the printed circuit board. The energy storage module is operatively connected to the discharge module by a first flexible member. The controller module is operatively connected to the energy storage module by a second flexible member. The first flexible member is folded such that the first portion of the printed circuit board is positioned substantially parallel to the second portion of the printed circuit board and the second flexible member is folded such that the third portion of the printed circuit board is positioned substantially perpendicular to the first and second portions of the printed circuit board.
