An electroporation probe that includes an injection means, allowing a single electroporation probe to be used for both the electroporation of cells and the injection of a fluid. The electroporation probe having (a) a probe body having an interior channel, a first end, and a second end； (b) a plurality of perforations in the probe body proximal the second end； (c) a sleeve positioned within the interior channel, wherein the sleeve is moveable between a first position sealing the perforations and a second position opening the perforations； (d) a connection between the probe body and an electroporation machine, wherein the probe body is in electrical communication with the electroporation machine； and (e) a tubing in fluid communication with the interior channel, wherein fluid injected into a proximal end of the tubing is exitable through the perforations when the sleeve is in the second position.
