During breaks at TEDMED, Children’s Hospital Boston is demonstrating a sampling of its technologies. Medgadget, the Internet Journal of Emerging Medical Technologies, came by to watch and posted these videos.
Above, Children’s engineer Pierre Dupont describes a new way of fixing children’s hearts — with enhanced, robot-guided catheters and tiny surgical tools that he’s developing with Pedro del Nido, chief of Cardiac Surgery. We hope these tools (shown at their true miniscule size and in large models) and the robotic system driving them will allow children, especially babies, avoid the rigors of open-heart surgery. Instead, a short-stay catheterization procedure could be performed while their hearts are still beating.
Here, Children’s epidemiologist-informatician John Brownstein explains some of the new features of HealthMap, an Internet-based infectious-disease tracking system. He zeroes in on Haiti’s emerging cholera outbreak, in which a “crisis mappers” community on the ground is sending real-time data to HealthMap via iPhone and iPad.

Move over, Ozzy Ozbourne. Next Wednesday, October 27th, Children’s neurologist-neuroscientist and TEDMED speaker Frances Jensen will compare and contrast the developing infant brain with the highly paradoxical teen brain – which is also developing rapidly, all the way to age 25 or so. Infant and teen brains are at opposite ends of the developmental spectrum — almost different species, Jensen says – but they’re both extremely dynamic and exquisitely sensitive to environmental factors (drugs and alcohol in teens and brain injury and seizures in infants). …
Combining microfabrication techniques from the computer industry with modern tissue engineering, a team at Children’s Hospital Boston and Harvard’s Wyss Institute for Biologically Inspired Engineering has created a device that mimics the function of a human lung. This living “lung-on-a-chip,” which incorporates human lung and blood-vessel cells, reproduces the all-important interface between the lung’s tiny air sacs and the bloodstream. Breathing is simulated with a vacuum pump.
The wafer-sized device mimics the human lung’s response to infectious agents, airborne particles and toxins in a way that’s truer to real life than standard cell testing in a lab dish. …
The seemingly random flailing of a newborn’s arms and legs is more important than it looks – it’s how babies begin to explore the physical world and their place in it. This motion-capture movie shows the normal kicking of a 5-month-old, but when a baby’s muscles are weakened by brain injury, this exploration is curtailed. It becomes a vicious cycle: the motor parts of the brain can’t develop properly, impairing mobility even further. Psychologist Eugene Goldfield, PhD, of the Center for Behavioral Science at Children’s Hospital Boston, with a team of engineers and scientists at the Wyss Institute, is in the early stages of a project that could help break this cycle for babies with cerebral palsy.
Goldfield calls it the “second skin” – smart clothing whose fabric, studded with tiny sensors, would pick up attempts at motion. …
Two or three years ago, seeing all the children in wheelchairs coming to Children’s Hospital, I asked myself whether I might be able to contribute something tangible to help restore their mobility. A psychologist by training, I had published some academic articles on how young children become independently mobile. But I’ve also always liked to build things.
