During the last 90 years there have appeared a number of instruments, devices and materials that can be used for replacing parts of living systems in human bodies. Those body implants materials which are able to function in close contact with the living tissue with the minimal adverse rejection or reaction to the body are called bio-materials. So, biomedical devices are those which are designed from these body implants materials and are able to exercise specific functions in the human body. At first, these body implants materials were used for bone plates. They were introduced in the 1900s in an attempt to stabilize different bone fractures as well as accelerate their healing. In the 1950s certain advances in body implants materials engineering and in surgical techniques led to the experiments based on the blood vessel replacement. The experiments of the 1960s dealt with artificial hip joints and heart valves. It is necessary to mention that the first implants of bone plate were not of high quality and caused a number of problems, such as the premature loss of the implant function. It was evidenced by corrosion, poor biocompatibility and mechanical failure. Biomedical devices and implants have three vital issues. They are material selection, biocompatibility and design. Health threat of infectious diseases decreased after the advent of antibiotics and the advances in medical sciences. As the life expectancy increased different degenerative diseases have become a true critical issue, especially in elderly people. It is natural that most joints and organs wear out with age. That is why it is of paramount importance to replace some body parts in order to maintain a high quality of life. It is biomaterials that play one of the leading roles in improving functioning of each body system (nervous, circulatory, skeletal, etc.). There are different types of implants. Orthopaedic implants include those for hip joints, bone fixators, spinal implants and total knee replacements. Cardiac implants are pacemakers and heart valves. Injectable collagen and breast implants are used for augmentation of soft tissues. Dental implants are applied for replacing bony tissue in oral cavities and root/teeth systems. It is necessary to note that implants play an serious role the health care in the USA. They also play an important economic part in the biomaterials industry. The implants and devices can also be made of such a material as medical plastics. Teflon implants are widely used as well. Artificial joints made of plastic are used for replacing hips, knees, fingers, wrists, shoulders and toe joints in order to restore the function that has been damaged by such conditions as arthritis, trauma from various sports injuries and other accidents. The average number of patients in the USA who have operations for joint replacements is 300,000 patients a year. Traditionally, the surgeries bring mobility and relief after long years of pain.
