1. An apparatus for non-thermal tissue ablation comprising:
a) a main body configured for handheld operation;
b) a tip comprising a skin-penetrating component comprising one or more sharpened hollow coring needles, wherein said tip is detachably attached to said main body and wherein each of said one or more sharpened hollow coring needles is configured to produce a plurality of ablated tissue portions by penetrating into and retracting from skin; and
c) a translating mechanism disposed in the main body for driving said one or more sharpened hollow coring needles across a region of the skin in one or two directions that are orthogonal to a longitudinal movement of the hollow coring needles penetrating into the skin and retracting the hollow coring needles from the skin.
