Despite numerous advancements in pacemaker technology for the treatment of cardiac arrhythmias and conduction disorders, lead-related complications associated with these devices continue to compromise patient safety and survival. In this work, we present a system architecture that has the capacity to deliver power to a wireless, batteryless intravascular pacer. This was made possible through a three-tiered, dual-sub-system, four-coil design, which operates on two different frequencies through intermittent remote-controlled inductive power transfer. System efficiency was enhanced using coil design optimization, and validated using numerical simulations and experimental analysis. Our pacemaker design was concepted to achieve inductive power transfer over a 55 mm range to a microscale pacer with a 3 mm diameter. Thus, the proposed system design enabled long-range wireless power transfer to a small implanted pacer with the capacity for intravascular deployment to the anterior cardiac vein. This proposed stent-like fixation mechanism can bypass the multitude of complications associated with pacemaker wires while wireless power can eliminate the need for repeated procedures for battery replacement.

使用异步三层感应式电力传输系统进行无线起搏。

尽管起搏器技术在治疗心律不齐和传导障碍方面取得了许多进步，但是与这些设备相关的铅相关并发症仍在危及患者的安全和生存。在这项工作中，我们提出了一种系统架构，该架构具有向无电池无线无线起搏器供电的能力。这是通过三层，双子系统，四线圈设计实现的，该设计通过间​​歇性的遥控感应式功率传输在两个不同的频率上运行。通过优化线圈设计提高了系统效率，并通过数值模拟和实验分析进行了验证。我们的起搏器设计旨在实现在55毫米范围内将感应功率传输至直径3毫米的微型起搏器。从而，拟议的系统设计能够将远程无线电力传输至小型植入式起搏器，并具有将血管内部署至心脏前静脉的能力。提出的这种类似支架的固定机制可以绕过与起搏器导线相关的众多并发症，而无线电源可以消除重复电池更换程序的需要。
