I just read a very interesting article, but I suggest you look it up real quick because I have a feeling someone is going to take it down. I can give you the link to it, but for some reason it doesn't work so what you have to do is type the entire title into your search bar, then hit on the link when it comes up. The link is http://www.softwarefreedom.org/resources/2010/transparent-medical-devices.html, but what you need to type into your search bar is the title, which is: 'Killed By Code' Transparency in Implantable Medical Devices This article is pretty scarey. It says that although there is yet to be a documented incident in which a source code for a medical device was breached for malicious purposes, a 2008 study done by software engineer and security expert Kevin Fu proved that it is possible to interfere with an ICD that has passed the FDA's premarket approval process and been implanted in hundreds of thousands of patients. Not only were these researchers able to first disable these devices, but they were then able to send multiple shocks averaging 137.7 volts that would induce ventricular fibrillation in a patient. Fu's findings showed that almost anyone could use store-bought ingredients to build a device that could easily be carried into a busy shopping mall or a subway, sending its' heart-attack command to random victims. Like I said, for some reason you have to type the entire article heading into your search bar to pull the article up, but trust me, it's worth reading.
