    Abstract: A device for generating skin grafts is disclosed, which includes a harvester having a distal end for placement on or in proximity of a portion of a subject's skin, where the harvester includes an orifice plate coupled to the distal end and having one or more openings. The device further includes a lid that is configured for attachment to the harvester to form a chamber and is configured for coupling to a vacuum source for generating a negative pressure in said chamber, thereby raising at least one blister through said at least one opening of the orifice plate. A skin-stretching mechanism is coupled to the harvester for stretching said skin portion so as to facilitate formation of said at least one blister. The harvester further includes a cutter integrated therein for cutting the blister. In some embodiments, the skin-stretching mechanism is coupled to the distal end of the harvester.
