Abstract:
An external medical device is provided. The device can include monitoring circuitry configured to sense physiological information of a patient and a controller with one or more input components. The controller can be configured to: detect one or more patient events based, at least in part, on the physiological information; notify the patient of the detection of the one or more patient events; and receive a patient response to the notification. The patient response can include a response activity identifiable by the input component, which is configured to test a psychomotor ability of the patient, cognitive ability of the patient, strength, balance, stability, and flexibility of the patient, and/or to substantially confirm that a person performing the activity is the patient.
Abstract:
An external medical device includes a battery that can support a plurality of charge-discharge cycles prior to a predetermined battery life threshold. The device also includes a battery circuit that is operative for monitoring a condition of the battery, determining a battery life status of the battery based on the monitored condition and the predetermined battery life threshold, and, responsive to the determined battery life status, causing the device to enter into a low power operating mode. The low power operating mode can include modifying device functions that are performed, or modifying the manner in which a capacitor of the device is charged, or changing the battery that charges the capacitor, or isolating the capacitor from charge drainage, or causing the device to operate from charge stored on the capacitor.
Abstract:
An ambulatory medical device comprises: a sensing component to be disposed on a patient for detecting a physiological signal of the patient; and monitoring and self-test circuitry configured for detecting a triggering event and initiating one or more self-tests based on detection of the triggering event. The ambulatory medical device senses the physiological signal of the patient substantially continuously over an extended period of time.
Abstract:
An ambulatory medical device including a plurality of electrodes configured to be disposed at spaced apart positions about a patient's body, an electrode signal acquisition circuit, and a monitoring circuit. The acquisition circuit has a plurality of inputs each electrically coupled to a respective electrode of the plurality of electrodes and is configured to sense a respective signal provided by a plurality of different pairings of the plurality of electrodes. The monitoring circuit is electrically coupled to an output of the acquisition circuit and is configured to analyze the respective signal provided by each of the plurality of different pairings and to instruct the acquisition circuit to select at least one of the plurality of different pairings to monitor based on at least one of the quality of the respective signal, a phase difference between the respective signal and that of other pairings, a position of electrodes relative to the patient's body, and other criteria.
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.

Abstract:
An external medical device including monitoring circuitry and communication circuitry. The monitoring circuitry monitors a cardiac condition of a patient using the external medical device. For example, the communication circuitry initiates a communication link with a remote location. The remote location can be selected based on data associated with at least one of the external medical device and the patient using the external medical device. In some examples, supporting data can be transmitted to the remote location.
