Scientists at Lawrence Livermore National Laboratory built a prototype of the Eyeglass telescope in 2002. ARTERY LINING A new stent graft devel- oped by University of Oxford scientists folds along helical creases for insertion by catheter into the abdominal aorta, then expands in place to sup- port the damaged artery. Human trials of the device could begin by 2012. The large lens (1) of the Eyeglass telescope would act as a magnifying glass, focusing light on a smaller "eyepiece" (2) orbiting half a mile or so away.
