Abstract
A tissue harvesting method and device for obtaining micrograft tissue particles within the size range of 50-1500 microns, and more preferably 500-1000 microns, and most preferably 600 microns. The particles may be processed after a piece of donor tissue has been excised from the donor site, or processed into the desired size directly at the donor site, and thereafter excised. Cutters having blades or cutting edges spaced in the range of 50-1500 microns are utilized to obtain particles within the desired size range. An elastomer is positioned between the cutting edges to push the excised particles out of the blades for ease of use.

1-51. (canceled)
A method of processing tissue, the method comprising:
- providing a donor tissue sample;
- providing a tissue cutter;
- engaging the tissue cutter with the donor tissue sample such that the tissue cutter cuts the donor tissue sample into a plurality of particles sized about 600 microns per axial x-y dimension;
- and
- removing the plurality of particles from the tissue-cutter.
A method of harvesting tissue, the method comprising:
- removing a dermal tissue section from a donor site;
- providing a tissue cutter, wherein the tissue cutter comprises a grid of cutting edges;
- engaging a portion of the dermal tissue section with the grid of cutting edges;
- and
- cutting the portion of the dermal tissue section into a plurality of particles.
A method of producing tissue particles, the method comprising:
- engaging a tissue cutter with a donor site;
- cutting a section of tissue at the donor site into a plurality of particles sized about 600 microns per axial x-y dimension;
- and
- removing a portion of the plurality of particles from the donor site.
