    • A circuit for use with a pulse width modulated integrated circuit having a soft-start reset function comprising a diode having a first terminal connected to a soft-start reset terminal of the integrated circuit, a voltage divider coupled between a voltage reference and a common terminal for the integrated circuit, the diode having a second terminal coupled to a tap of the voltage divider and a soft-start capacitor coupled between the second terminal of the diode and the common terminal whereby upon power startup of the integrated circuit, the soft-start capacitor is charged by the tap of the voltage divider and wherein in the event of a single event upset condition, when the soft-start reset terminal of the integrated circuit is reduced to a level at or near the level of the common terminal of the integrated circuit, the diode prevents the soft-start capacitor from discharging through the integrated circuit.

    • A circulatory support system and method for circulatory support are described for performing cardiopulmonary bypass using differential perfusion and/or isolated segmental perfusion of the circulatory system. The circulatory support system includes one or more venous cannulae for draining blood from the venous side of the patient's circulatory system, one or more arterial cannulae for perfusing the arterial side of the patient's circulatory system, and one or more blood circulation pumps connected between the venous cannulae and the arterial cannulae. The arterial cannulae and the venous cannulae of the circulatory support system may take one of several possible configurations. The circulatory support system is configured to segment a patient's circulatory system into one or more isolated circulatory loops. The circulatory loops may be isolated from one another and/or from the remainder of the patient's circulatory system on the venous side, as well as on the arterial side, for isolated closed loop circulatory support of separate organ systems. The circulatory support system is suitable for use in minimally-invasive cardiac surgery, using thoracoscopic, port-access or minithoracotomy techniques, or for standard open-chest cardiac surgery.
    • 描述了用于循环支持的循环支持系统和方法,用于使用循环系统的差分灌注和/或分离的分段灌注进行心肺分流术。 循环支持系统包括用于从患者循环系统的静脉侧排出血液的一个或多个静脉插管,用于灌注患者循环系统的动脉侧的一个或多个动脉插管和连接在患者循环系统的动脉侧的一个或多个血液循环泵 插管和动脉插管。 循环支持系统的动脉插管和静脉插管可以采取几种可能的构型之一。 循环支持系统被配置为将患者的循环系统分成一个或多个隔离的循环循环。 循环循环可以彼此隔离和/或从静脉侧以及动脉侧的患者循环系统的其余部分分离,用于分离的器官系统的闭环循环支持。 循环支持系统适用于微创心脏手术,使用胸腔镜,门禁或小切开术技术或标准胸腔心脏手术。
