    • The present invention provides advancements in the art of cardiac pacemakers. The invention provides a pacemaker system that comprises at least one pacemaker and that is, to a large extent, self-controlled, allows for long-term implantation in a patient, and minimizes current inconveniences and problems associated with battery life. The invention further includes a mechanism in which at least two pacemakers are implanted in a patient, and in which the pacemakers communicate with each other at the time of a given pacing or respiratory event, without any required external input, and adjust pacing parameters to respond to the patient's need for blood flow. The invention further provides a design for a pacemaker in which the pacemaker electrode is connected to the pacemaker body by a lead that is configured to allow the pacemaker to lie parallel to the epicardial surface and to reduce stress on the pacemaker and heart tissue.
    • 本发明提供心脏起搏器领域的进步。 本发明提供了一种起搏器系统,其包括至少一个起搏器,并且在很大程度上是自我控制的,允许长期植入患者体内,并且最小化与电池寿命相关的当前不便和问题。 本发明还包括一种机构,其中至少两个起搏器被植入患者体内,并且其中起搏器在给定的起搏或呼吸事件时彼此通信,而没有任何需要的外部输入,并且调整起搏参数以响应 对患者的血液流动需求。 本发明还提供了一种起搏器的设计,其中起搏器电极通过引线连接到起搏器主体,所述引线被构造成允许起搏器平行于心外膜表面平行并且减小起搏器和心脏组织上的压力。

    • Charge-based charge pumps are described which include a switchable capacitor configured for connection to a voltage source, a ground, and a charge pump output. A first pair of switches include a first switch configured to connect the switchable capacitor to ground and a second switch configured to connect the switchable capacitor to the voltage source. A second pair of switches include a third switch configured to connect a first node, between the switchable capacitor and ground, to the charge pump output, and a fourth switch configured to connect a second node, between the switchable capacitor and the voltage source, to the charge pump output. Locked loop designs, such as phase locked loops or delay locked loops, are described that include charge-based charge pumps.
