Disclosed is a wearable cardiac therapeutic system including a plurality of therapy electrodes disposed in a garment and a fluid pressure source including a barrel configured to house the conductive gel and an actuation mechanism. A therapy controller is configured to detect an arrhythmic event in a patient based on sensed electrical activity of the patient's heart, initiate an activation signal indicating that the conductive gel is to be released on to the body of the patient, and cause the delivery of one or more electrical therapeutic shocks to the heart of the patient. Gel activator circuitry is configured to receive the activation signal from the therapy controller, and cause the fluid pressure source to expel the conductive gel onto the body of the patient proximate the one or more of the therapy electrodes and prior to the delivery of the one or more electrical shocks to the patient.

Systems and methods for conductive gel deployment

A serviceable wearable cardiac treatment device for continuous extended use by an ambulatory patient includes a garment and a device controller. The garment is configured to dispose therein a plurality of ECG sensing and therapy electrodes. The device controller is configured to be in separable electrical communication with the plurality of ECG sensing and therapy electrodes. The device controller includes an impact-resistant energy core, including a frame and capacitor(s) permanently bonded to the frame. The device controller includes a critical function circuit board, including critical function processor(s) and circuitry, and a non-critical function circuit board, including non-critical function processor(s) and circuitry. The critical function circuit board is in electrical communication with the capacitor(s) and configured to control critical operations of the device controller regardless of operability of the non-critical function circuit board. The non-critical function circuit board is configured to control non-critical operations of the device controller.

Wearable medical device controller with capacitor framing

A therapy electrode system comprises a garment configured to be worn about a torso of a patient, a therapy electrode disposed in the garment and configured to deliver one or more electrical shocks to a body of the patient, a replaceable gel cartridge disposed on the therapy electrode and configured to release a conductive gel onto the patient's skin at an interface between the therapy electrode and the patient's skin prior to the delivery of the one or more electrical shocks to the body of the patient at the interface between the therapy electrode and the patient's skin, and a fluid pump in fluid communication with the replaceable gel cartridge.

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.

An electrode system includes a gel deployment receptacle configured to release a conductive gel onto a body of a subject and a fluid pump in fluid communication with the gel deployment receptacle.

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.

Systems and methods for utilizing identification devices in a wearable medical therapy device

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.

External case for a wearable medical device

According to another example, a wearable medical device controller is provided. The device controller includes a memory and a processor coupled to the memory. The processor is configured to determine a correlation between a phenomenon identifiable by the wearable medical device controller and at least one response pattern associated with a patient and store, responsive to detecting the correlation, an adaptation path to address the at least one response pattern, the adaptation path specifying an adaptation of at least one characteristic of an alarm. The at least one response pattern may include a plurality of response patterns and the adaptation path may reflect adaptations made to address at least some of the plurality of response patterns.
