What is a Medical Device? What’s the difference vs a medicine?

A medical device is typically a product that works on or inside the human body, with either temporary or permanent impact, and is aimed at prevention, diagnosis, monitoring or treatment of diseases. The key difference versus traditional medicines is that a medical device works primarily mechanically as opposed to pharmacologically, i.e. it works alongside or with your body versus affecting the chemistry of human cells. Nowadays medical devices are used for alleviating and treating many severe and chronic diseases of the heart, brain, bladder, digestive tract etc. with superior efficacy to traditional therapy based on chemical molecules. This is because they typically work directly where your body needs help.
