41、 is free of viable microorganisms. International standards, which specify requirements for validation and routine control of sterilization processes, require, when it is necessary to supply a sterile medical device, that adventitious microbiological contamination of a medical device prior to sterili

42、zation be minimized. Even so, medical devices produced under standard manufacturing conditions in accordance with the requirements for quality management systems (see, for example, ISO 13485) may, prior to sterilization, have microorganisms on them, albeit in low numbers. The purpose of sterilizatio

43、n is to inactivate the microbiological contaminants and thereby transform the non-sterile medical devices into sterile ones. The kinetics of inactivation of a pure culture of microorganisms by physical and/or chemical agents used to sterilize medical devices can generally best be described by an exp

44、onential relationship between the numbers of microorganisms surviving and the extent of treatment with the sterilizing agent; inevitably this means that there is always a finite probability that a microorganism may survive regardless of the extent of treatment applied. For a given treatment, the pro

45、bability of survival is determined by the number and resistance of microorganisms and by the environment in which the organisms exist during treatment. It follows that the sterility of any one medical device in a population of items subjected to sterilization processing cannot be guaranteed and the

46、sterility of a processed population is defined in terms of the probability of there being a viable microorganism present on a medical device. Attention also has to be given to a number of factors, including the microbiological status (bioburden) of incoming raw materials and/or components and their

47、subsequent storage, and to the control of the environment in which the product is manufactured, assembled and packaged (see also ISO 13485). Requirements for quality management systems for medical device production are given in ISO 13485. The standards for quality management systems recognize that,

48、for certain processes used in manufacturing, the effectiveness of the process cannot be fully verified by subsequent inspection and testing of the product. Sterilization is an example of such a process. For this reason, sterilization processes are validated for use, the performance of the sterilizat

49、ion process is monitored routinely and the equipment is maintained. Animal tissues and their derivatives are used as constituents of certain medical devices to provide performance characteristics that present advantages over the characteristics provided by non-animal-based materials. The range and quantities of materials of animal origin in medical devices vary; such materials can comprise a major part of the device, can be a product coating or impregnation, or can be used in the
