Across the U.S millions of Americans live their lives with implants in their body, designed to help them overcome medical problems. So many Americans still are treated with medical devices that have not been rigorously tested.

There are hundreds of horror stories on the internet of what happens when these medical devices go wrong. From cases like the well-known Medtronic class action lawsuit to the Therac-25, which gave patients morethan 100 times the radioactive dose they were meant to receive. Tthe side effects from the following infamous devices make you wonder how they ever passed the testing phase at all.


Possibly one of the most shocking cases of medical devices going wrong the Therac-25 was a device designed to administer radiotherapy to patients in the 1980s. Controlled by a computer, the machine accidentally administered radiation doses that were hundreds of times stronger than what they were meant to be. Between 1985 and 1987, six accidents happened where, because of computer programming errors, patients ended up being given severe radiation poisoning. This resulted in the death or serious injury of each patient. Three of the patients died from this poisoning.

Two of the accidents happened because a fault in the machine because the radiotherapy was administered in the wrong mode. In previous models, there were locks in place that had to be overridden by a real person, in the Therac-25 these locks were removed; instead, the locks were controlled by a computer program. These accidents happened when a flaw in this programming, allowed for the machine to activate in the wrong mode.
