Medical devices can perform a plurality of functions, such as sensing, monitoring, deriving and/or calculating various physiological statuses of a patient (e.g., blood pressure, temperature, respiration rate, etc.). Medical devices can also be used to image part or all of a patient's body, to deliver a treatment, or to manage information related to a patient's care. The present disclosure is directed at one or more devices that perform these functions using a plurality of processing circuits, wherein each processing circuit has a timing circuit with a local clock. These processing circuits can be connected via a network, and each timing circuit can communicate with at least one other timing circuit in order to detect and correct time-differences between their local clocks. In this way, multiple processing circuits can be synchronized with each other to facilitate diagnosis or treatment of a patient's condition, or other aspects of a patient's care.

A system for providing remote assistance to a caregiver during a medical event includes a computer tablet with a transmitter/receiver to communicably couple the tablet with a remote computing system associated with central caregivers, physiological sensors for collecting patient information, and a defibrillator configured to couple to the sensors and including a transmitter/receiver to communicably couple the defibrillator and tablet, and a processor to receive the patient information from the sensors, provide the patient information for display, and communicate the patient information to the tablet, the tablet being configured to generate a user alert for communications with the remote system based on a signal indicating that resuscitative treatment of the victim is being administered, the signal including the patient information received from the sensors, and the user alert including a request for a confirmation to initiate communications with the remote system, and, in response, establish communications with the remote system.

A display for outputting information contents of at least one parameter, adjustment value or measurement value of medical devices within at least one display region, wherein the at least one display region is in the form of a tachometer-like display.

A patient-worn arrhythmia monitoring and treatment device includes a pair of therapy electrodes and at least one pair of sensing electrodes disposed proximate to the skin and configured to continually sense at least one ECG signal of the patient over an extended period of time. The device includes a therapy delivery circuit coupled to the pair of therapy electrodes and configured to deliver one or more therapeutic pulses. A controller coupled to therapy delivery circuit is configured to analyze the at least one ECG signal and detect one or more treatable arrhythmias and cause the therapy delivery circuit to deliver the one or more therapeutic pulses to the patient. At least one of the one or more therapeutic pulses is formed as a biphasic waveform delivering within 15 percent of 360 J of energy to a patient body having a transthoracic impedance from about 20 to about 200 ohms.

An automated wearable belt cardiac defibrillator (BCD) for wearing by a subject, comprising: at least two patches adapted for adhering to the subject each comprising a defibrillation electrode and an ECG sensor; and a BCD controller connected to each of the patches, wherein the patches comprise an adhesive adapted for long-term adhering of the patches to the subject, wherein the adhesive is a biocompatible adhesive, wherein the patches and adhesive are adapted for movement of the subject while the patches are adhered to the subject, wherein the patches are replaceable, wherein the controller is housed in a belt for wearing by the subject, wherein the belt is adapted for being flexible, wherein the adaptation for being flexible comprises a plurality of compartments for housing components of the controller, wherein a method for usage of the BCD comprises: following completion of an operational period, positioning of the patches to alternative locations on the subject wherein each of the alternate locations represents an alternate shock vector.

Disclosed are a timeline-based navigation feature and a channel selection feature. The timeline-based navigation feature allows the user to visually identify significant events during an episode and quickly navigate the display of data to those significant events. Embodiments of such feature allow a user to quickly see that there is a shock delivered, for example, and click on that part of a timeline navigator to advance the detailed display of data to that point in the episode. The data channel selection feature enables selection of display channel(s) from among a set of available data channels. Embodiments of such feature enable a selection and/or deselection of various channels for display to minimize display of extraneous data and/or to select preferred channels of data for review.

Methods and devices are described for preventing diastolic flow reversal and/or reducing peripheral vascular resistance in a patient. Also described are methods of cosmetic treatment, and methods of promoting delivery of therapeutic agents or contrast agents to bones and related tissues.

A wearable cardiac monitoring and treatment device for improved skin interface contact and easy assembly and disassembly includes a garment including an inner surface and an outer surface, ECG sensing electrodes, and at least one stiffener forming a section of the garment in proximity to one or more of the ECG sensing electrodes. The at least one stiffener is configured to resist rotation or pulling away of the one or more of the ECG sensing electrodes from a patient's torso. The device includes therapy electrodes, at least one separate module including a therapy delivery circuit, and a controller. The device includes compartments configured to receive the therapy electrodes and at least one separate module, and retention loops configured to route external wires extending between at least the therapy electrodes and at least one separate module, where the compartments and retention loops are disposed on the outer surface of the garment.

A charging circuit for a capacitor in a defibrillator includes a control enabling a setting of a desired time to charge a capacitor to a desired voltage in the defibrillator. The charging circuit further includes a flyback charge-pump circuit comprising a switch, an energy transfer transformer, an energy storage capacitor and a control. The switch is configured to stop or allow storage of energy in a transformer. The transformer transfers the energy to the capacitor. The flyback charge-pump circuit controls a duty-cycle on the switch so that a current draw from a power source (e.g. battery) is sufficient to enable charging the capacitor to the desired voltage within the desired time set on the control.

In one embodiment, a method to differentiate between causes of noise in an electrocardiogram (ECG) signal. The method connecting to at least one sensing electrode and obtaining the ECG signal from the at least one sensing electrode. The method also includes detecting noise on the ECG signal and detecting ancillary conditions. The method also includes associating the noise on the ECG signal with at least one of the ancillary conditions and providing an actionable indication to a patient associated with the noise on the ECG signal.
