Exemplary methods and devices can be provided for harvesting a plurality of small tissue pieces, e.g., having widths less than about 1 mm or 0.5 mm, using one or more hollow needles. A fluid can be flowed through a conduit past the proximal ends of the needles to facilitate removal of the tissue pieces from the needle lumens, and can maintain the tissue pieces in a controlled and protective liquid environment. A filter can be used to extract and collect the tissue pieces from the liquid, or the tissue pieces can be deposited directly onto a porous dressing. Such tissue pieces can be used as microscopic grafts, which can be applied directly to a wound site or provided on a substrate or dressing, or stored for later use. Such microscopic grafts can promote tissue regrowth and wound healing, or can be applied to a scaffold to grow new tissue.

Method and apparatus for tissue harvesting

The present disclosure relates to exemplary embodiments of method and apparatus for harvesting, handling and implanting small tissue grafts obtained from a donor site. In some embodiments the apparatus includes hollow needles and base that can be formed of one or more biocompatible materials that are biodegradable and/or dissolvable.
