Natural or artificial (man-made) materials that make up all or part of a living structure or biomedical device are known as biomaterials. Biomaterials are materials that interact with biological systems, whether they are natural or synthetic, alive or dead, and usually made up of many components. In medical applications, biomaterials are frequently employed to supplement or replace natural functions. A well-designed biomaterial should perform its function in the living body's environment without causing harm to other organs. To achieve this, a biomaterial must be nontoxic. Biomaterials Science is an important component of the larger field of Biomedical Engineering. Biomedical Engineering and Biomaterials have embraced biology as a basic science on which they build, whereas Engineering, and Materials Science by extension, used to get their basis from mathematics, physics, and chemistry
A medical device is any instrument, equipment, implement, machine, appliance, implant, in vitro reagent, software, material, or other similar or related product that the manufacturer intends to be used for a medical purpose, either alone or in combination. On the global market today, there are an estimated 2 million different types of medical devices, divided into about 7000 generic device groups. A medical device is a gadget that is used to diagnose, prevent, or treat a medical disease or condition without affecting any portion of the body chemically. Medical devices are an important part of health-care systems, and the benefits they can give are growing.
