Embodiment Construction

[0054] The systems and methods disclosed herein enhance the safety of delivering therapeutic energy to patients. For example, the systems and methods may include verifying system integrity before, during, or after delivery of therapeutic energy and provide mechanisms for rapidly terminating delivery of potentially harmful energy. The system may include an energy generator having processing circuitry to determine whether a fault condition exists in the system and automatically terminate delivery of therapeutic energy when the processing circuitry determines that a fault condition exists. The method may generally include performing a series of pre-checks, synchronizing therapeutic energy delivery with appropriate segments of the cardiac depolarization pattern, configuring the system for therapeutic energy delivery, delivering therapeutic energy, monitoring during energy delivery, and perform post-treatment evaluations.

Abstract

A system and method for the safe delivery of treatment energy to a patient, which includes verification of system integrity before, during, or after the delivery of treatment energy and provides several mechanisms for rapid termination of the delivery of potentially harmful energy to the patient when a fault condition in the device and/or system is identified. The system may include an energy generator having processing circuitry to determine if there is a fault condition in the system and to automatically terminate a delivery of treatment energy when the processing circuitry determines thereis a fault condition. The method may generally include performing a series of pre-checks, synchronizing a treatment energy delivery to the proper segment of the heart's depolarization pattern, configuring the system for treatment energy delivery, delivering the treatment energy, and performing post-treatment evaluation.

Description

technical field [0001] The invention relates to a method and a system for protective measures applied to energy generators. Background technique [0002] Arrhythmias disrupt normal heart rhythm and heart efficiency. These arrhythmias can be treated using application of therapeutic energy, such as pulsed field ablation (PFA) energy, radio frequency (RF) energy, pulsed RF energy, ultrasound energy, etc., and / or removal of heat from tissue by cryotherapy. During the PFA procedure, safe and effective therapy requires that the systems that generate and deliver high levels of electrical energy be in good operating condition. [0003] In the event of an electrical failure of the PFA energy generator, a potential hazard to the patient may arise. While medical device standards (for example, those established by the International Electrotechnical Commission IEC) limit inadvertent patient currents to less than 10 microamps (1e-5 amps), applying 10 mA or more from a PFA energy generat...
