Experimental drug release and arterial drug uptake data obtained from drug-eluting stent implants within porcine coronary arteries. (A) Fractional Drug Release from the Stent, (B) Average Arterial Drug Concentrations. Quantification of drug released from the stent and absorbed by the arterial wall was obtained for 1, 8, 14, 30, 60, 90 days post-implantation. (Note: all error bars represent the standard deviation from the mean.)
