1. A fluidic device comprising:
a first inlet;
an outlet;
a channel positioned between the first inlet and the outlet, wherein the channel is in fluid communication with the first inlet and the outlet;
a second inlet positioned between the first inlet and the outlet, wherein the second inlet is in fluid communication with the channel; and
a pump in fluid communication with the second inlet, wherein the pump is configured to provide a first volume of pulsatile flow to the channel towards a side of a first biological specimen to dislodge the first biological specimen from a first needle positioned at least partially in the channel, and wherein the first volume of pulsatile flow is greater than about 50 μL per pulse.
