Biomaterials are any substance or combination of substances synthetic or natural in origin, which can be used for any period of time, as a whole or as a part of a system which treats arguments or replaces any tissue, organ or function of the body.
Biomaterials are used to measure, restore, and improve physiological function and enhance survival and quality of life, biocompatibility: that means non-toxic, noncarcinogenic and noninflammatory.
*First generation implants:
These are specified by physicians using common and borrowed materials
eg: Parachute cloth vascular implants/Vascular implants
*Second generation implants
These are engineered implants using common and borrowed materials developed through collaborations of physicians and engineers built on first-generation experiences used advances in materials science
eg: heart valves and pacemakers
*Third generation implants are bioengineered implants using bioengineered materials on the market some modified and new polymeric devices may under development
eg: Substitute heart valves

Worldwide Medical Devices (WMD) manufactures medical diagnostic equipment at several locations across Europe. WMD has traditionally manufactured high-quality large medical equipment for use in hospitals. Recently, the firm has developed a new technology that makes testing vitamin D deficiency at GP surgeries affordable, avoiding the need to send patients’ blood to testing laboratories. WMD has spent £50m designing and developing this new generation of equipment for the European domestic market. The costs to complete the final stages of regulatory approval...
