To mimic the hemodynamic environment, we have designed a pulsatile bioreactor system. In particular, fluid mechanical theories and equations were applied to measure the real pressure inside vascular scaffolds, which characterize the compliance and strength of the scaffolds The bioreactor system was used to measure the compliance of poly(L-lactide-co-epsilon-caprolactone) (PLCL), an elastic polymer, scaffolds The compliance of a PLCL scaffold in 80 similar to 120 mmHg was 0 753 (%mm/100 mmHg). The compliance of a PLCL scaffold ranged 0 722 to 0.989(%mm/100 mmHg) The possibility of measuring pressure inside vascular scaffolds in real time in vitro will provide the inspiration of enhancing properties of scaffold and will improve our investigation on the scaffold in vascular processes.
