Art Please refresh me & tell what this device is & where I can locate the magazine. Thanks In a message dated 98-01-08 10:43:31 EST, you write: << The January, 1998, edition of Spectrum Magazine, published by the IEEE, includes an article on medical technology, featuring the Medtronic device. It is available on the web, but alas only to IEEE members. In the magazine, find it on page 62. It may be of interest to many of us - and I for one would have missed it had it not been pointed out by a friend. Art Arthur Hirsch [] [log in to unmask] [] Lewisville, TX >>
