WHAT MEDICINE NEEDS: Frugal Innovation. “A low-cost pocket ultrasound device can see into the human heart. So why do so few doctors use it? . . . Medicine, in short, has the potential for better technology at a much lower price, but don’t look to the medical profession, government, or the life-sciences industry to make the change on its own. I believe the change will come when consumers demand it.”
