We are joined by award-winning medical investigative reporter Jeanne Lenzer. Her first book, “The Danger Within Us: America's Untested, Unregulated Medical Device Industry and One Man's Battle to Survive It.” Lenzer puts forward strong arguments that the medical device industry is under-regulated. Woven through her analysis is the story of one patient’s dangers and difficult journey involving an implanted device together with related stories about physicians and researchers.
