A catheter extended from a large blood vessel below its neck—a carotid artery. Into the catheter, a surgeon injected a steel bead slightly larger than the ball of a ballpoint pen.

In a room next door, my engineering graduate students and I held our breath. We were testing a program designed to manipulate the machine’s magnetic forces, which would guide the bead like a remote-controlled submarine. Or so we hoped. . . . Read Complete Report
