The invention discloses an in-vitro performance testing
system and testing method of a transcatheter
bicuspid valve valved
stent, and relates to prostheses capable of being implanted
in vivo, in particular to a testing device and testing method applied to
heart valve performance testing. The in-vitro performance testing
system comprises a valve testing part which is internally provided with the
bicuspid valve valved
stent, a
liquid circulation device and a monitoring device; a first testing part is a heart specimen of which the left ventricular apex is provided with a circulation inlet, and asecond testing part is a section of artificial
blood vessel or a section of
blood vessel specimen for sewing the tested
bicuspid valve valved
stent; the liquid testing device is connected with the first testing part to constitute a first testing circulating path for steady flow circulation and a second testing circulating path for simulating the ventricular beat of the
human body; the
liquid circulation device is connected with the second testing part to constitute a third testing circulating path which is connected with circulation lateral branches,
in vitro tests of fluid mechanic performance, support fixing states, valve
backflow, perivalvular leakage, and influences on surrounding important organization structures of the bicuspid valve valved stent can be achieved, and a durability experiment of the bicuspid valve valved stent is completed.
