Borrowing technology from the space program, a new computerized, implanted insulin pump controlled by radio signals and computer chips appears to help some diabetics avoid daily insulin injections, researchers reported. The hockey puck-sized device is “a significant advance,” said Dr. Christopher D. Saudek of Johns Hopkins University, who helped test the device. Researchers said they plan to test a slightly modified version before seeking Food and Drug Administration approval, and noted it could be years away from becoming commercially available. The pump was tested on 18 diabetics. Doctors said it generally worked well, although four of the devices became blocked when tissue grew over the catheter that releases the insulin. One also malfunctioned because of a faulty microchip.
