Challenge

 

Extracorporeal membrane oxygenation therapy (ECMO) has improved clinical outcomes and survival rates for both adults and pediatric patients with respiratory compromise. However, current ECMO systems have several fundamental limitations: they are large and bulky, they greatly restrict patient movement, and the membranes used for gas exchange are inefficient and with high doses of anticoagulation required to overcome the high likelihood of blood clots.

Solution

 

HEAL

The High-efficiency External Ambulatory Lung (HEAL) seeks to address these issues via a novel approach in gas exchange membrane fabrication: specifically, a micron-thin film of PDMS supported by a specialized silicon microporous membrane to create an efficient and robust gas exchange membrane. The geometry of this approach minimizes stagnant blood flow zones and reduces the risk of clots, thus obviating the need for high doses of anticoagulation and risk of bleeding. This technology also enables the system to be miniaturized into a portable, wearable device, enabling greater patient movement and improved recovery times. By offering a wearable, low resistance, low volume oxygenator that minimizes anticoagulation requirements, the HEAL has the potential to revolutionize the market for extracorporeal membrane oxygenators.
