Shunts often are surgically placed in the brains of infants with hydrocephalus to drain excess cerebrospinal fluid. Unfortunately, these devices eventually fail, and the problem is hard to detect until the child shows neurologic symptoms. CT and MRI scans may then be performed to check for a blockage of flow—followed by urgent neurosurgery if the shunt has failed.
Early detection of shunt failure was the problem pitched last fall at Hacking Pediatrics in Boston. Two bioengineers, Christopher Lee, a PhD student at Harvard-MIT Health Sciences and Technology program, and Babak Movassaghi, PhD, an MBA candidate at MIT Sloan, took the bait.
“We heard that parents would not take vacations in areas without an experienced neurosurgeon around,” says Movassaghi, a former Philips Healthcare engineer with 32 patents in cardiology and electrophysiology. “We were intrigued to solve that.” Full story »
