My five year old came home from school the other day talking about how the shortest distance between two points is a straight line. That got me thinking about how a straight line might be the most direct route, but it’s not always the best one. For example, pilots fly around large thunderstorms because it is safer for the passengers…and the crew! So safety becomes the over-arching factor when determining the flight plan, even if the diversion uses a little more gas.
Medical devices are in a similar position of requiring a consideration of human lives. Therefore, linear thinking is probably not good enough when developing a new device. We must transition to the non-linear realm if we are to bring the safest devices to market.
Non-linear analysis will allow us to make great leaps forward in our understanding of device performance. But this will require us to cope with modeling complexities that may or may not have been dealt with in the past. Let me mention three typical sources of non-linear complexities: Continue reading
