Systems and methods for controlling a mobile defibrillator (AED) unit are provided.

Provided are a defibrillation catheter system, a defibrillation power supply device, and a method for controlling the device during observation of intracardiac potential and defibrillation. A defibrillation catheter system 1 includes a catheter 20; a first power supply part 6A and a second power supply part 6B connected to the catheter 20; and an electrocardiograph 40 measuring an intracardiac potential, wherein the catheter 20 is provided with a first electrode group 21 having at least a 1-1 electrode and a 1-2 electrode and a second electrode group 22 having at least a 2-1 electrode and a 2-2 electrode, the first and second electrode groups 21 and 22 are connected to the electrocardiograph 40, the 1-1 electrode and the 2-1 electrode are connected to the first power supply part 6A, and the 1-2 electrode and the 2-2 electrode are connected to the second power supply part 6B.

A wearable defibrillator system includes a support structure with one or more electrodes in an unbiased state. A monitoring device monitors, for the long term, a parameter of the person that is not the person's ECG; rather, the monitored parameter can be the person's motion, a physiological parameter, or both. When a value of the monitored parameter reaches a threshold, such as when the person is having an actionable episode, the electrode becomes mechanically biased against the person's body, for making good electrical contact. Then, if necessary, the person can be given electrical therapy, such as defibrillation. As such, the electrodes of the wearable defibrillator system can be worn loosely for the long term, without making good electrical contact. This can reduce the person's aversion to wearing the defibrillation system.

An implantable medical device system is configured to detect a tachyarrhythmia from a cardiac electrical signal and start an ATP therapy delay period. The implantable medical device determines whether the cardiac electrical signal received during the ATP therapy delay period satisfies ATP delivery criteria. A therapy delivery module is controlled to cancel the delayed ATP therapy if the ATP delivery criteria are not met and deliver the delayed ATP therapy if the ATP delivery criteria are met.

A wearable therapeutic device includes a garment configured to be worn on a torso of a patient. The garment has an anterior portion and a posterior portion. The garment is configured to house at least one defibrillator component, a first therapy electrode disposed in the anterior portion of the garment, a second therapy electrode disposed in the posterior portion of the garment, and an alarm module configured to alert the patient of an impending defibrillation shock from the at least one defibrillator component to be delivered by at least one of the first therapy electrode and the second therapy electrode. The first therapy electrode and the second therapy electrode are configured to be electrically coupled to the at least one defibrillator component. At least one of the first therapy electrode and the second therapy electrode is at least one of woven into the garment and comprises a textile material.

An implantable antibacterial barrier device for an elongated medical device, the elongated medical device configured to extend from a first site, through a second site, to a third site. The implantable antibacterial barrier device includes a housing configured to be disposed at the first site, a working electrode configured to be disposed at the second site, and a reference electrode configured to be disposed at the first site. The housing includes barrier circuitry. The working electrode electrically is coupled to the barrier circuitry. The reference electrode is electrically coupled to the barrier circuitry. The barrier circuitry is configured to selectively maintain the working electrode at a negative electrical potential relative to the reference electrode to form an antibacterial barrier.

A rescue cell apparatus used for cardiac defibrillation of a patient, the apparatus comprising: a hand held device for sending and receiving communication signals and configured to be used as a remote control to administer a defibrillation pulse to the patient for cardiac defibrillation; a defibrillator unit having a sensor electronic pad positionable on the patient, the sensor electronic pad adapted to deliver the defibrillation pulse; and a second electronic pad, connectable by an electrical wire to the defibrillator unit, the second electronic pad positionable on the patient and adapted to detect ECG signals and to deliver the defibrillation pulse to the patient; and an image recognition module configured in the handheld device, and adapted to verify positioning of the sensor electronic pad and the second electronic pad on the patient before defibrillation.

A method for performing CPR with a mobile defibrillator (AED) unit can include detecting, via an application on a user device, a connection of a mobile AED unit to the user device; detecting, via the application, that pads have been attached to a subject, the pads comprising at least one accelerometer; recording, via the application, EKG measurements of the subject made by the pads; receiving accelerometer data from the at least one accelerometer; analyzing the accelerometer data to determine a breathing pattern of the subject; and based on the determined breathing pattern, initiating a CPR protocol.

A subcutaneous implantable medical device and method (SIMD) provided. A pulse generator (PG) is configured to be positioned subcutaneously within a lateral region of a chest of a patient. The PG has a housing that includes a PG electrode. The PG has an electronics module. An elongated lead is electrically coupled to the pulse generator. The elongated lead includes a first electrode that is configured to be positioned along a first parasternal region proximate a sternum of the patient and a second electrode that is configured to be positioned at an anterior region of the patient. The first and second electrodes are coupled to be electrically common with one another. The electronics module is configured to provide electrical shocks for antiarrhythmic therapy along at least one shocking vector between the PG electrode and the first and second electrodes.

Implantable cardiac systems and methods for providing substernal pacing in an ICD system are described. In one example, an implantable cardiac system comprises an ICD system and an implantable leadless pacing device (LPD) communicatively coupled to the ICD system. The ICD system includes an ICD and an implantable defibrillation lead having a proximal portion coupled to the ICD and a distal portion having a defibrillation electrode configured to deliver a defibrillation shock to a heart of the patient. The LPD includes a housing, a first electrode on the housing, a second electrode on the housing, and a pulse generator within the housing and electrically coupled to the first electrode and the second electrode. The housing of the LPD is implanted substantially within an anterior mediastinum of the patient and the pulse generator is configured to deliver pacing pulses to a heart via the first and second electrodes.
