1. Atualização de sistema duplicador de pulsos para teste de proteses de valvulas cardiacas / Upgrade of a pulse duplicator system for cardiac valve prostheses evaluation
It has become very frequent the use of mechanic or biological cardiac valve prostheses. These prostheses must be evaluated (in vitro and in vivo tests) in order to be used clinically. The hydrodynamic performance tests are carried out in vitro. The analyses of the test results are very important for the characterizations and classification of a given prosthe

2. Avaliação das propriedades do pericardio bovino liofilizado
Lyophilization of bovine pericardium (BP) in patches or manufactured valves may provide improved storage, sterilization, and handling. This paper describes the appraisal of some consequences of lyophilization on BP. Mechanical properties and shrinkage temperatures (ST) of six groups of BP, 50 samples each, were evaluated. Groups were: (1) fresh BP; (2) BP fr
