title: [Cardiovascular biomaterials].
abstract: Hemocompatible biomaterials, i.e. materials to be used in a biological environment, are of various origins (biological, synthetic). The great variety of physical and chemical characteristics has allowed design of various prosthesis and artificial organs. Use of biomaterials and artificial organs has made possible the development of substitutive therapies, a growing component of medical care. None of the biomaterials presently used is ideal. Everyone of them is responsible for a local and general reaction: foreign body reaction, coagulation, whole body inflammatory response. For years, these reactions have been poorly understood and development was of a very empirical nature. Progress in cellular and molecular biology permits today a better understanding of the mechanisms involved in these reactions. Use of biomaterials is facing to day a difficult problem; liability concerns threaten further developments and leads to market withdrawal of major basic materials.
