3-D Printed Airway Splint for Babies

3-D Printed Airway Splint for BabiesAt the University of Michigan, printers spit out problem sets and term papers. Now there’s one that makes biodegradable medical devices, allowing babies with a potentially fatal condition to grow up and live a normal life.

The new device is called an airway splint. It’s designed to support the tiny airways near the lungs that are prone to collapse in patients with tracheobronchomalacia.

So far, the medical implant has been tested in three children between the ages of 3 months and 16 months. Before getting the implant, the young patients had spent much of their lives in intensive care, where they needed to be on ventilators full-time to help them breathe.

But after surgeons inserted the small white device around their narrow airways, all three recovered rapidly, according to a study published this week in the journal Science Translational Medicine.

In the past few years, 3-D printers have expanded the possibilities for doctors and their patients. With customized blueprints and the right mix of ingredients, the printers can make prosthetic hands, ears and even samples of livers, kidneys and other tissues.

But the airway splint is the first 3D implant made for kids and designed to grow along with the patient.

“We used laser light to transform dust into a medical device that changes how the body develops,” Green said. “It would have been inconceivable when I was a resident” in the 1990s.
