What’s the most interesting Medical Device project you’ve worked on and why?

The LVAD Controller. V&V testing was very hands-on and brought me into test laboratories that I hadn’t worked in before. The technology was fascinating – a spiral motor with ruby bearings – as were the customer stories. A person who wears a LVAD has no pulse!

If you could work on any type of medical device project, what would it be and why would you want to work on it?

I would love to work on a medical device that departs from Western medicine and instead takes on a wellness approach. How about a device that removes environmental toxins from the body? Or something that identifies nutrient deficiencies and quickly brings the blood chemistry back into balance? If we could develop a device that speeds up the body’s ability to heal from trauma or disease, that would be amazing.
