Finding new cures for migraine, depression

Accepting his 2005 TED Prize, inventor Robert Fischell makes three wishes: redesigning a portable migraine treatment, finding new cures for clinical depression, and reforming the medical malpractice system. He also shares three new inventions that could improve the lives of millions: His Angel Med Guardian System -- a pacemaker-sized device wired into the heart -- detects an elevation in the electric signal of the heart, the first sign of a heart attack. His transcranial magnetic stimulator treats migraines with a magnetic pulse. Finally, the Neuropace prevents epileptic seizures by transmitting electric signals in the brain.
