help analyze people with sleep disorders without having them spend a night in a hospital or otherwise monitored room hooked up to a complex set of electrodes and machines. That device, the SleepShirt, is a shirt with sensors that monitor a person's sleep to diagnose irregularities such as sleep apnea. The students who developed the shirt created a startup called Rest Devices to commercialize the shirt and also are working on a baby onesie that can allow parents or caregivers to monitor children while they sleep. Sensors inside the clothing send information to a smartphone application or tablet via a wireless connection. Another device from the class is being commercialized through a startup formed by MIT PhD candidate Danielle Zurovcik, Hanumara said. The device is a low-energy system for negative pressure wound therapy, which draws fluid out of an ulcer or a sucking wound to promote healing. The device is based on the idea that it's the seal and not the amount of pressure that is key to the device. "The energy (for the device) can be a bellows expanding, like a toilet plunger," Hanumara said. "If you connect that up and seal your connection really well, it can actually work." Other devices designed by the class that could make their way into the medical field include a thoracoscopic screwdriver used to place screws to repair cracked ribs from the inside, and a low-cost, lightweight robot for imageguided lung biopsies. A company has licensed the screwdriver prototype as an enabling technology, Hanumara said, declining to divulge specifics on the company or the deal. The latter resulted in a working prototype, a worldwide patent that has been approved in China, and numerous follow-on research projects and funding, Rajiv Gupta, an MD and PhD with Massachusetts General Hospital and Harvard Medical School who worked on the project in 2004 with the class, told us. Gupta called the ability to work closely with teams on devices "a unique and exciting opportunity" that "gives me a way to look at the problems I face [w ww. d e s i g n n e w s . c om] magenta cyan yellow black in routine practice of medicine in a completely different light." He said that while there are other project-oriented courses like this one at MIT and other universities, the oppor- tunity to pair physicians and students to create devices from a clinical rather than a technological perspective is unique.
