Biomedical engineer Dr. Joseph Potkay is working with high-resolution 3D Printing company Old World Labs on a research funded by the VA (Veteran Affairs), to create a prototype of the 3D printed artificial lung, which will be about a half-inch cube in size, hopefully able to fit in a backpack and be used for a week. It will be the first truly wearable artificial lung that’s compatible with living tissue and can provide both short- and long-term respiratory support, and microfluidic artificial lungs. The device has been tested in rabbits, with sheep testing planned for the future.
