  • providing a device comprising a negative pressure chamber with a removable cap, an orifice plate removably fitted to a lower end of the chamber and having a plurality of openings through which skin blisters can be raised, a cutter comprising a cutter plate having at least one hole, the cutter integrated and fitted within the chamber above the orifice plate such that at least a portion of the blisters protrudes through the at least one hole in the cutter and being movable within the chamber, and at least one light source coupled to the chamber and configured to deliver radiative energy into the chamber for heating an interior of the chamber and the orifice plate;

    contacting the orifice plate to skin at a donor site;

    utilizing said at least one light source to heat the interior of the chamber and the orifice plate with radiative energy, thereby warming the skin at the donor site so as to facilitate formation of skin blisters through said openings;

    raising a plurality of suction blisters through the openings in the orifice plate; and
