Abstract：
The shortcomings of expense, power requirements, infection, durability, size, and blood trauma of current durable LVADs have been recognized for many years. The LVADs of tomorrow aspire to be fully implantable, durable, mitigate infectious risk, mimic the pulsatile nature of the native cardiac cycle, as well as minimize bleeding and thrombosis. Power draw, battery cycle lifespan and trans-cutaneous energy transmission remain barriers to completely implantable systems. Potential solutions include decreases in pump electrical draw, improving battery lifecycle technology and better trans-cutaneous energy transmission, potentially from Free-range Resonant Electrical Energy Delivery. In this review, we briefly discuss the history of LVADs and summarize the LVAD devices in the development pipeline seeking to address these issues.
摘要：
费用的缺点，功率要求,感染,耐用性,尺寸,目前耐用LVAD的血液创伤已被确认多年。明天的LVAD渴望完全可植入，耐用,减轻感染风险，模仿自然心动周期的脉动性质，以及减少出血和血栓形成。功率消耗,电池循环寿命和经皮能量传输仍然是完全可植入系统的障碍。潜在的解决方案包括减少泵的电力消耗，改善电池生命周期技术和更好的经皮能量传输，可能来自自由范围谐振电能输送。在这次审查中,我们简要讨论了LVAD的历史，并总结了寻求解决这些问题的开发管道中的LVAD设备。
