摘要： The present invention outlines structures and methods for delivering a controllable amount of energy to a patient by automatically compensating for the load impedance detected by an implantable-cardioverter defibrillator (ICD). The invention employs high speed, switching power converter technology for the efficient generation of high energy, arbitrary waveforms. Unlike a linear amplifier, switching power converters deliver high-energy waveforms with an efficiency that is independent of the size and amplitude of the desired waveform. An ICD that uses a switching power converter to deliver the desired energy to the patient stores the energy to be delivered in a storage capacitor. The converter then transforms this energy into an arbitrarily shaped output voltage-controlled or current-controlled waveform by switching the storage capacitor in and out of the output circuit at a high rate of speed. Preferably, the waveform comprises a ramp-type waveform.

摘要翻译：本发明概述了通过自动补偿由可植入式心律转复除颤器（ICD）检测的负载阻抗来向患者传送可控量的能量的结构和方法。本发明采用高速，开关电源转换器技术，高效生成高能量，任意波形。与线性放大器不同，开关电源转换器提供高能量波形，效率与所需波形的大小和幅度无关。使用开关功率转换器将期望的能量递送到患者的ICD存储要在存储电容器中传递的能量。然后，转换器通过以高速率切换存储电容器输入和输出输出电路，将该能量转换成任意形状的输出电压控制或电流控制波形。优选地，波形包括斜坡型波形。
