Like 500,000 other Americans each year, Lee was suffering a stroke. Something had cut off the flow of oxygen and nutrient-rich blood to a portion of her brain. Sometimes the culprit is a leaky artery. But in Phillips' case, as in 80% of strokes, the problem, revealed by a CAT scan, was a clot that was plugging up one of the blood vessels in her head.

Now, however, they can simply plug the opening with a cone-shaped mesh device. Plugging rather than patching the hole causes less strain on the surrounding tissue and reduces the extent of both surgery and recovery time...
