Biomaterials dedicated for valve prostheses - Testing system

The physico-chemical modificated biomaterials dedicated for valve prostheses have been tested in varius methods for optymalisation the process of its treatment. Theres were tested fresh, cryopreservated, glutardehyded (GA) and photoxidated material. The data includes results of the qualification test and computer simulation of valve work, stress-strain and shrinkaige temperature and calcification (in vivo and in vivo). As a conclusion was stated that our system consist of constructed ourself devices passed successfully all tests and is able for testing different types of biomaterial and heart valves prostheses. The treatment by GA is simpler and shows better repeatability of measurements than photoxidation. Because the results of tests of the photooxidated tissue are promising, we work on automatisation and better controlling the process.
