摘要: The goal of this study was to design, fabricate, and characterize a biocompatible flow chamber the performance artificial heart valves. system consists testing fluid water (separated by latex diaphragm), following design left ventricular assist device. Two St. Jude bileaflet mechanical valves were placed oppositely in control direction. rate set at 5.6 L/min, with stroke volume 80 ml. examined through three-dimensional numerical simulation vitro experiments whole blood washed platelets. Hemolysis measured using spectrophotometer. Platelet activation platelet surface P-selectin expression cytometry. computational dynamics model demonstrated that field laminar physiological. Results from indicated conditions did not induce hemolysis or presence Overall, can provide feasible environment hemodynamic
