Wanted: Specially Designed Tools For Pediatric Surgery : Shots - Health News Pediatric surgeons often have to improvise the tools of their trade, because surgical instruments are not often designed specifically for children. Some surgeons are teaming up with engineers to try to change this.

Another problem in pediatric medicine takes place in the hospital. That's where surgeons who work on children and infants often find themselves without the tools they need. From member station KQED, Amy Standen reports.



AMY STANDEN, BYLINE: Inside the neonatal intensive care unit at the University of California San Francisco Benioff Children's Hospital, Nurse Marti Thompson is swaddling an infant not much bigger than a burrito.

THOMPSON: You're a knucklehead.

STANDEN: Some of these babies were born prematurely. Others were born with congenital defects, some part of their internal anatomy that just didn't develop the way it's supposed to.

THOMPSON: Their diaphragm missing, and part of their intestine's in their chest, or some cardiac defect that needs to be fixed, because there's no way they would be able to grow and sustain a life without having surgery.

STANDEN: In other words, what Sanjeev Dutta calls...

DR. SANJEEV DUTTA: Plumbing problems, essentially.

STANDEN: Dutta is a pediatric surgeon, which means it's his job to fix exactly these kinds of problems. He works at Lucile Packard Children's Hospital in Palo Alto, California. Dutta says often, the instruments he uses weren't built for tiny babies. They were made for adults.

DUTTA: So we sort of struggle with instruments that were never designed for the type of patient that we're operating on.

STANDEN: Dutta says the issue here isn't really safety. Most of these surgeries are, by now, pretty routine. But pediatric surgeons have to improvise in ways that other surgeons don't. And physically, sometimes this can be pretty awkward.

DUTTA: Really, I have to stand about a foot and a half away from the patient in order to just do the operation, because the instrument's so big.

STANDEN: Partly because of problems like these, pediatric surgeons have a reputation as being mavericks, people who are particularly good at improvising.

Take Mike Harrison, also at UCSF's Benioff Children's Hospital. Harrison is known as the father of fetal surgery, working on the smallest patients of all, those still in the womb. He says, 20 years ago, when the field was just getting started, his team had to make almost everything from scratch.

DR. MIKE HARRISON: We had to make up all the tools and devices that allowed the fetal surgery because the tools were 10 times too big.

STANDEN: Harrison describes this era - the 1970s and early 80s - as a sort of golden age of pediatric surgery; a time when you could rig up a new tool, run your own tests and then bring it into the operating room. He says he never felt like they had a choice.

HARRISON: It's almost a moral imperative. Because it's usually in a circumstance where this kid is going to die. The only way we think we might be able to save him is this new way. We'd have to have this new thing. Let's just go do it. And that's what we can't do now.

STANDEN: That's because things have changed. In the late '70s, the FDA began regulating surgical devices, much the same way it regulates some drugs. It now can take a more than a decade to get a device to market - longer for pediatrics. Harrison says that this, along with the fact that these procedures are rare, has had a chilling effect on manufacturers.

HARRISON: The market is too small to justify the research and development for new devices. That's the fundamental problem.

STANDEN: So in 2007, in an effort to help spur innovation in pediatrics, Congress set aside a small pot of money - about $3 million for each two-year cycle, split among several different teams. The idea was to bring together doctors and engineers to work together on problems in pediatric medicine. Harrison says traditionally these can seem like two very different worlds.

HARRISON: We were, you know, sort of blood and guts and, hey, we got to have this device, it's - going into the operating room tomorrow, and they were thinking nanotechnology and, you know, and science.

STANDEN: But the FDA money is making these partnerships routine at UCSF and several other hospitals across the country.

Sanjeev Dutta, of Packard Children's Hospital, has paired up with an engineer named Pablo Garcia.

PABLO GARCIA: All these are all racks of screws and nuts.


STANDEN: Garcia works at a nonprofit research institute called SRI International in Menlo Park, California. In 2009, he and Sanjeev Dutta received $500,000 from the FDA to fund their collaboration.

GARCIA: You want to do this, Sanjeev?

DUTTA: No, you go ahead. I mean why don't you show these three?


STANDEN: Garcia and Dutta are standing around a table in Garcia's engineering lab, rifling through a pile of metal gadgets - prototypes.

DUTTA: This is a sort of favorite tool of mine that we worked on. It's one of the very early projects that we started on.

STANDEN: It's a plastic grip, kind of like what you'd hold on to on a paint roller, attached to a thin metal tube with a tiny clamp at the end. It's designed to treat a condition called esophageal atresia.

DUTTA: The esophagus, which is the swallowing tube that goes down to the stomach, has a gap in it. The child is born with a gap in that tube and so therefore can't eat.

STANDEN: So Dutta and Garcia's tool is designed to make surgery on this problem a lot easier, and much less invasive. But it will be years before this device ever makes it into the operating room.

Dutta and Garcia's grant from the FDA has run out. They hope that private philanthropy will sponsor their device to the point where a manufacturer might see the profit in making it.
