Acellularization of heart valves

IWASAKI, Kiyotaka Professor (Faculty of Science and Engineering Graduate School of Advanced Science and Engineering Cooperative Major in Advanced Biomedical Sciences)
One of the ways of prolonging the life of tissue valves is to not treat them chemically, and use acellular tissue from porcine heart valves. A unique method of microwave irradiation combined with a simulated in vivo environment (controlled surfactant flow and pressure through ...
