(A) Average distribution ratio at Vi = 450 μL for MINT at 9 μL/min total flow rate (i.e., 3 μL/min per cannula) vs. single-needle CED at 3 μL/min flow rate. (B) Infusion duration to reach Vi = 450 uL for MINT at 9 μL/min total flow rate (i.e., 3 μL/min per cannula) vs. single-needle CED at 3 μL/min flow rate. Error bars represent ± S.D. from n = 3 trials for multipoint at each flow rate condition and n = 4 trials for single-needle CED.
