The University of Michigan surgeon and engineer who saved a baby’s life with a 3D-printed airway splint have won a Breakthrough Innovator Award from Popular Mechanics magazine.

The award winners are Glenn Green, M.D., associate professor of pediatric otolaryngology, and Scott Hollister, Ph.D., professor of biomedical engineering and mechanical engineering and associate professor of surgery.

Perhaps the biggest winner, though, is Kaiba Gionfriddo, the 3-year-old from Youngstown, Ohio, who received an emergency experimental treatment at C.S. Mott Children’s Hospital in 2012 for his severe tracheobronchomalacia, a rare condition that caused his airways to collapse routinely. The case is believed to be the first instance of a 3D-printed device saving a life.

Within the first two months of his life, Kaiba stopped breathing and turned blue twice. His first hospital stay was 10 days. His second was much longer.

“Quite a few doctors said he had a good chance of not leaving the hospital alive,” said April Gionfriddo, Kaiba’s mother. “It was the most devastating thing that a parent could hear.”

Treatments weren’t working, so Green and Hollister obtained emergency clearance from the Food and Drug Administration to implant a custom support to hold open a portion of Kaiba’s windpipe to give him the chance to grow out of his condition over the next few years.

Green, a pediatric ear, nose and throat surgeon, had been focusing on airway collapse treatments for several years. Hollister, a tissue engineering specialist, had been developing implantable 3D-printed scaffolds that could encourage new bone and tissue growth and eventually disintegrate into the body. The two were in the process of testing a splint like the one they used, but they hadn’t yet tested it in people.

To make the splint, they conducted a CT scan of Kaiba’s trachea and bronchus — one of the branches of his respiratory tract that connect to his lungs. They used the images to create a computer model of his body and then designed and printed a thimble-sized sleeve that could slip over the affected part of his airway. When they implanted it in February 2012, Kaiba’s lungs started going up and down on their own, right on the surgical table.

More than a year after the procedure, with Kaiba having had no recurrences, The New England Journal of Medicine featured the case in May 2013.

Hollister and Green are one of 10 teams that received awards at a ceremony in New York City on October 22.

“This is a great honor,” Green said. “This work could only be accomplished with the tremendous support and interactions available at the University of Michigan.”

Hollister echoed Green’s sentiment on collaboration, and added that they and others here are aiming to broaden the use of the technology.

“I believe 3D-printed medical devices will change the face of medicine and dramatically improve patient care,” Hollister said. “The University of Michigan and its partners are working diligently to bring 3D-printed medical devices into clinical use so that we may improve the quality of life for many more patients.”
