Given Imaging ( GIVN) has a product that could revolutionize the health care industry, Jim Cramer told viewers of his "Mad Money" TV show on Speculation Friday. The Given System is a wireless imaging system that uses disposable video capsules, he explained. And the company sells a medical device called the PillCam, a pill-sized camera that people swallow to detect internal problems. Israel-based Given has already used its PillCam capsule for endoscopy procedures in which cameras have checked out patients' upper and lower intestines. This method, Cramer said, seems much more comfortable than checking out gastronomical problems the old-fashioned way.
