Abstract
A device and methodology for concomitant ejection and suction of a perfusate (CESOP) within a region of interest without spillover of the perfusate to a juxtaposed anatomical region. An inflow line, connected to a perfusate cistern, is coupled to an outflow line, connected to outflow control mechanisms, via an elongate rigid support. Perfusate can flow through the inflow line to the region of interest, and nearly simultaneously, the outflow line can suction the perfusate out of the region of interest. The amount of time that the perfusate remains in the region of interest is sufficient to take effect in the region of interest. The rigid support helps control the inflow and outflow lines. A micromanipulator can also be used to control the lines and application tip thereof. Either or both lines may also have adjustable flow rates therethrough and may include stoppers/regulators.
