What does Medtronic do to ensure the device is reliable?

Different manufacturers, and countries, have different standards for reliability.Medtronic likes a good challenge, so they vigorously test devices in the lab, during clinical trials, and submit all the data for the FDA to review and approve.But it doesn't end there. After a device is released, Medtronic tracks device performance in patients and does post-market studies to ensure that devices work in real life just as well as they test.
