Implantable cardiac devices and methods

摘要

Embodiments relate to an implantable cardiac system and methods, including a housing, electronic circuitry for controlling one or more of power management, processing unit, information memory and management circuit, sensing and simulation output and how these operate. The system also includes diagnosis and treatment software for diagnosing health issues, diagnosing mechanical issues, determining therapy output and manage patient health indicators over time, a power supply system including at least one rechargeable battery, a recharging system, an alarm (or alert) system to inform patient of energy level and integrity of system, communication circuitry, one or more electrodes for delivering therapeutic signal to a heart and one or more electrodes for from delivering electrocardiogram signal from the heart to the electronic circuitry, and body orientation determination, in various aspects.

主权项

1. A method for treatment of a patient with a risk for experiencing a ventricular fibrillation or sudden cardiac death event, the method comprising:
a healthcare professional implanting a first device into the patient in anticipation of the patient experiencing a ventricular fibrillation or a sudden cardiac death event, wherein the first device comprises therapy circuitry configured to apply defibrillation therapy to the patient, and wherein the first device is configured to (i) monitor the patient's heart to determine if the patient has experienced a ventricular fibrillation or sudden cardiac death event, (ii) store data associated with a determined ventricular fibrillation or sudden cardiac death event, (iii) determine whether the therapy circuitry has exceeded a pre-programmed reliable operational life threshold, (iii) apply defibrillation therapy to the patient's heart via the therapy circuitry in response to determining that both (iii-a) the patient has experienced a ventricular fibrillation or sudden cardiac death event and (iii-b) the therapy circuitry has not exceeded the pre-programmed reliable operational life threshold, and (iv) disable the therapy circuitry's ability to apply defibrillation therapy to the patient's heart in response to determining that the therapy circuitry has exceeded the pre-programmed reliable operational life threshold; and after the first device has applied defibrillation therapy to the patient's heart, the healthcare professional, or one or more other healthcare professionals, (i) analyzing the data associated with a determined ventricular fibrillation or sudden cardiac death event, (ii) selecting an implantable cardiac device having at least one operational feature based on the analysis of the data associated with the determined ventricular fibrillation or sudden cardiac death event, (iii) extracting the first device from the patient; and (iv) implanting the selected implantable cardiac device into the patient, wherein the selected implantable cardiac device is configured to perform at least one function that the first device is not configured to perform.
