Normalized sustained leakage flow for the Bjork–Shiley monostrut tilting disk valve with Delrin occluder after soaking in physiologic saline, 40/60 glycerin/water, NaI/glycerin/water, and saturated NaI solution. Baseline flow rate is 1.5 liters per minute.
Grahic Jump Location
Normalized sustained leakage flow for the St. Jude Medical Bileaflet valve (pyrolytic carbon) after soaking in physiologic saline, 40/60 glycerin/water, and NaI/glycerin/water solution. Baseline flow rate is 0.8 liters per minute.
