    • A hollow tubular element is inserted in the descending aorta. The caudad end contains a pressure sensitive passive or preferably, hydraulically or electrically activated, unidirectional valve. A flexible diaphragm situated in a rigid shell affixed over an opening in the element wall divides the shell interior into first and second variable volume chambers. The first chamber opens to the artery. A continuously operating electrical pump is connected to the second chamber through a closed hydraulic system including a multi-valve chamber. The valves regulate fluid flow to the second chamber in accordance with electrical signals from the heart. Fluid flow is directed to the second chamber during cardiac diastole and away from the second chamber during cardiac systole, causing the device to function in a counterpulsation mode. The work of the heart is decreased and coronary blood flow is increased to promote the formation of new coronary collateral channels and the perfusion of the heart itself. In the event of mechanical failure, pre-implantation heart function is not impeded.
    • 中空管状元件插入降主动脉。 尾端包含压敏的被动或优选的液压或电活动的单向阀。 位于固定在元件壁上的开口上的刚性壳体中的柔性隔膜将壳体内部分成第一和第二可变体积腔室。 第一个房间通向动脉。 连续运行的电动泵通过包括多阀室的封闭液压系统连接到第二室。 阀门根据来自心脏的电信号调节流到第二腔室的流体流量。 在心脏收缩期间,心脏舒张期和远离第二腔室的流体流动被引导到第二腔室,导致装置以反搏模式起作用。 心脏的工作减少,冠状动脉血流量增加,以促进新冠状动脉旁路通道的形成和心脏本身的灌注。 在机械故障的情况下,植入前心脏功能不受阻碍。
