Abstract

Disclosed are a device and a method for fixing an artificial bioprosthetic valve by membrane pervaporation. The device comprises a storage tank (15) for storing a reactant liquid a fixation clamp (9) for fixing the artificial bioprosthetic valve a pervaporation membrane assembly (14) a reaction chamber (13) and a vacuum pump (12) the fixation clamp (9) being located inside the reaction chamber (13) the pervaporation membrane assembly (14) being located inside the reaction chamber (13) upstream of the fixation clamp (9) the storage tank (15) being connected to the reaction chamber (13) upstream of the reaction chamber (13) and the vacuum pump (12) being connected to the reaction chamber (13) downstream of the reaction chamber (13). The method comprises the following steps: fixing one end of the artificial bioprosthetic valve to the fixation clamp (9) of the device and leaving the other end freely suspended; activating the vacuum pump (12); activating the pervaporation membrane assembly (14) to allow the vaporised reactant liquid to enter the reaction chamber (13) and permeate through the pervaporation membrane assembly (14) to the artificial bioprosthetic valve; and reacting the artificial bioprosthetic valve in the reaction chamber (13) for a period of time.
