DESCRIPTION (provided by applicant): For twenty years prolonged extracorporeal life support (ECLS ECMO) has been standard treatment for infants with severe heart or lung failure unresponsive to other treatment. The healthy survival rate in over 30,000 cases ranges from 40% in cardiac arrest to 95% in meconium aspiration. Improved treatment has resulted in decreased need for ECMO in full term neonatal respiratory failure, but the application to respiratory failure in older infants, cardiac failure, and sepsis is increasing. The devices used fr ECMO are individual components from several manufacturers, assembled on site, and used "off label." Recently three companies have combined the devices into an integrated "ECMO system." These are designed for older children and adults but require substantial modification for infants. The goal of this project is to design, test, and produce a life support system specifically for infants (1 through 10 kg, 1 day to 2 years age); we call this MiniECMO. Phase l aims include integration of the MC3 BioLung and MPump devices with cartridge heat modules and an automated sweep gas controller. The system will be coated with our unique nonthrombogenic NO secreting polymer to decrease or eliminate the need for systemic anticoagulation. The prototype system will be fabricated and tested in vitro to demonstrate safety, efficacy and durability. A pilot in vivo study will be conducted to measure durability of gs exchange, properties of the MiniLung, and to evaluate thrombogenicity. Phase ll will include extended testing of MiniECMO for safety and efficacy, development of a clinical ready device, and a clinical trial for ten patients conducted under an investigational device exemption (IDE). The University of Michigan Extracorporeal Life Support Lab and Michigan Critical Care Consultants are the leaders in this field and can bring this technology to reality in four years.

描述（由申请人提供）：20年来，延长体外生命支持（ECLS ECMO）一直是对其他治疗无反应的重度心力衰竭或肺衰竭婴儿的标准治疗。超过30，000例病例的健康存活率从心脏骤停的40%到胎粪吸入的95%不等。改进的治疗已导致足月新生儿呼吸衰竭对ECMO的需求减少，但对较大婴儿呼吸衰竭、心力衰竭和败血症的应用正在增加。ECMO使用的设备是来自几个制造商的独立组件，在现场组装，并“标签外使用”。最近有三家公司将这些设备组合成一个集成的ECMO系统。“这些是为年龄较大的儿童和成人设计的，但需要对婴儿进行大量修改。该项目的目标是设计、测试和生产专门用于婴儿（1至10公斤，1天至2岁）的生命支持系统;我们称之为MiniECMO。阶段1的目标包括MC 3 BioLung和MPump设备与盒加热模块和自动吹扫气体控制器的集成。该系统将涂有我们独特的非血栓形成NO分泌聚合物，以减少或消除对全身抗凝的需要。原型系统将在体外制造和测试，以证明安全性，有效性和耐用性。将进行初步体内研究，以测量gs交换的耐久性、MiniLung的特性，并评价血栓形成性。第二阶段将包括MiniECMO的安全性和有效性的扩展测试，临床就绪设备的开发，以及在研究设备豁免（IDE）下对10名患者进行的临床试验。密歇根大学生命支持实验室和密歇根重症监护顾问是该领域的领导者，可以在四年内将这项技术变为现实。
