Founded in 2015 by extracorporeal life-support experts, Pittsburgh-based Advanced Respiratory Technologies is developing artificial lungs and a wearable Pulmonary Assist System for long-term respiratory support. Its battery-powered, 3.2-kilogram system is designed to give people with chronic lung disease greater mobility and a path home from intensive care, while also supporting military transport. ART has produced a third-generation prototype and has received more than $22 million in grant funding during its development.
