Medical devices are instruments, apparatuses, implements, machines, contrivances,
implants, or in vitro diagnostics and are intended for the cure, mitigation, treatment,
diagnosis, or prevention of disease. They are intended to affect the structure or function
of the body through means other than chemical action and independently of being
metabolized. In the past few decades there has been greater recognition of how critical
they are to delivering state-of-the-art medical care, as their use in the delivery of medical
care has always been ubiquitous.
