Dispatches - in a joint investigation with the BMJ - explores what's implanted into our bodies. Almost 40 million of us come into contact with a medical device every day. That includes everything from a basic sticking plaster to hi-tech coils implanted into the arteries leading to the heart. The medical device industry is worth over £200 billion a year. Dispatches investigates whether in the drive for innovation, patient safety can come second. The programme reveals that although these medical devices save thousands of lives every day, there are questions from patients and doctors about the amount of testing that these products go through before they go on general sale.
