I used to work in a the Department of Veterans Affairs in a group called War Related Illness and Injury Study Center (WRIISC). This group has a couple of biomedical engineers that make medical devices and test them on veterans. The problem was always with funding. The way we were funded was that we had to write papers on the research we were doing and send it to different companies. These companies could then give us funding to continue our research. This means that our research using this device has to be very thorough, meaningful and complete for a company to consider it. If it was lacking data it would automatically be discarded. The more data you collect with your medical device and the more analysis you perform, the more interested the company will be in the device.
