A treatment device for facilitating performance of a procedure on a target, comprising:(a) a transparent material which surrounds a delivery system at an output and which is capable of conducting light in a direction corresponding to that of electromagnetic energy directed by the delivery system from the output distally away from the treatment device and into a volume distally disposed of the treatment device(b) at least three fluid outputs arranged on a distal end of the transparent material, pointed away from the treatment device toward the volume, and configured to propagate fluid distally away from the treatment device toward the volume to thereby place the propagating fluid into the electromagnetic energy, within the volume, as the electromagnetic energy is directed distally away from the treatment device into the volume.
