BiomaterialDefinitionAny type of material, surface, or construct that interacts with a biological system, whether natural or man-made, that includes all or part of a living structure or a biomedical expedient that can perform, enhance, or replace a function lost due to disease or injury. Substance or preparation intended to be implanted in a living being to replace an organ or bodily tissue. (Prostheses, from the simplest [dental] to the most complicated [artificial trachea], are made with biomaterials.) Any substance (except drugs) or combination of substances, of artificial or natural origin, which can be used at any time, as a whole. or as part of a structure that treats, supplements, or replaces any body tissue, body part, or body function (NIH). Biomaterials are the materials that create parts of medicinal grafts, extracorporeal devices and disposable devices that have been used. in medicine, surgery, dentistry and veterinary medicine as well as all aspects of patient health care.HistoryA first generation of biomaterials included until the mid-20th century, corrosion-resistant metals and alloys later used in dental surgery and orthopedic. Fabrics or knitted polyester were used after 1950 as vascular prosthesis materials. All of these materials share the same characteristic of not having been produced specifically for biomedical applications. It is the secondary properties of resistance to corrosion, mechanical stress and wear, as well as their relative inertness with respect to living tissues, which have been exploited. Implanting an artificial larynx is very complex. Until now, no biomaterial was suitable for this body. Engineer André Walder, with a surgical team at ...... middle of the paper valve ......, or St. Jude valve. This mechanics involves two semi-circular discs moving back and forth, which allow blood circulation and the ability to form a seal against backflow. The valve is covered in pyrolytic carbon and protected from adjacent tissues by a fabric mesh called DacronTM. The network allows body tissues to occur by joining the valve. Skin repair “Artificial” tissue is grown from the patient’s own cells. However, when the damage is so dangerous that it is unbearable to use the patient's own cells, artificial tissue cells are grown. The problem lies in finding a scaffold on which cells can grow and organize. The characteristics of the support must be that it is biocompatible; the cells can adhere to the support, mechanically durable and recyclable. An effective carrier is a copolymer of lactic acid and glycolic acid..
