1. A method for non-thermal tissue ablation comprising:
a) providing a handheld device having a main body and a tip, wherein said tip comprises one or more sharpened hollow coring needles, the tip being detachably attached to the main body;
b) penetrating into and retracting the one or more sharpened hollow coring needles into a skin to produce a plurality of ablated tissue portions; and
c) 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 one or more sharpened hollow coring needles penetrating into the skin and retracting the one or more sharpened hollow coring needles from the skin, using a translating mechanism disposed in the main body.
