Defective medical devices — and the lack of laws or enforcement against them — have killed thousands of patients around the world and put millions more at risk.

The multi-million-dollar medical implant and medical device companies are shrouded in a myriad of scandals related to conflicts of interest, corruption and abusive practices toward patients.
