Inductively powering a minimally invasive heart pump

仅在美国就有600多万人受到心力衰竭的影响。每年，有66万新病例被诊断为 成本接近350亿美元。对于这些患者中的200万人(美国)来说，药物不再能控制问题 而机械支持血流是最容易获得的治疗方法。然而，心脏泵需要电力， 今天使用的经皮引线仍然是不良事件的重要原因。我们建议取消 使用无线电力传输的经皮铅。 米勒(德克萨斯州休斯敦)已经开发出从内部线圈接收电能的技术(US14/432,120) 该物体由位于该物体外部的线圈产生的磁场产生。我们的研究目的是要证明 无线电源技术与Procyrion(德克萨斯州休斯敦)Aortix心脏泵的融合如何 消除经皮传动系感染的风险。 我们将测量无线电源系统在一年内提供5W电力时产生的热量 外部线圈和植入线圈之间的距离可变，最大间距可达20 mm。这个功率水平是足够的 用于全泵运行和为内部(短期)电池充电。 我们的长期目标是使Aortix成为III期心衰患者的首选治疗方案

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
