Heart failure affects over 6 million people in the US alone. Every year, 660,000 new cases are diagnosed with a cost approaching $35 billion. For 2 million of these patients (US), drugs can no longer control the problem and mechanical support for blood flow is the most accessible treatment. However, heart pumps need power, and percutaneous leads used today remain a significant cause of adverse events. We propose eliminating the percutanous lead by using wireless power transfer. Millar (Houston, TX) has develped the technology (US14/432,120) to receive electrical power from a coil inside the body from a magnetic field generated from a coil located outside the body. Our research aim is to show how the merging of the wireless power technology with the Procyrion (Houston, TX) Aortix heart pump can eliminate the risk of percutaneous driveline infections. We will measure the heat generated by the wireless power system when delivering 5W of power over a variable distance of up to 20mm separation between external and implanted coils. This power level is adequate for full pump operation and recharging an internal (short-term) battery. Our long-term goal is make the Aortix the preferred treatment option for stage III HF patients

仅在美国，心力衰竭就会影响超过600万人。每年，有660,000例新病例被诊断出 费用接近350亿美元。对于这些患者（美国）中有200万，药物无法再控制这个问题 对血流的机械支持是最容易获得的治疗方法。但是，心脏泵需要力量， 当今使用的经皮铅仍然是不良事件的重要原因。我们建议消除 使用无线电源传递的经皮引线。 Millar（德克萨斯州休斯顿）已开发了该技术（US14/432,120），从内部的线圈接收电力 从位于人体外部线圈产生的磁场的身体。我们的研究目的是显示 无线电源技术与Procyrion（德克萨斯州休斯顿）Aortix Heart Pump的合并如何可以 消除经皮动力传播感染的风险。 我们将测量无线电源系统产生的热量，当 外部和植入线圈之间的可变距离可变距离20mm。这个功率水平足够 用于全面泵操作并为内部（短期）电池充电。 我们的长期目标是使AORTIX成为III期HF患者的首选治疗选择
