Abstract: An article is configured for transferring tissue cores from a patient donor site to a patient wound site. The article includes a matrix construction of resilient elastomeric polymer material to support an array of tissue core locators individually defining an opening and individually configured to: (1) receive a tissue core from the donor site into the opening, (2) resiliently hold the tissue core at the opening until and after the sheet is placed upon the wound site, and (3) release the tissue core when the sheet is removed from the wound site at a time that is between 2 and 29 days after the sheet is placed upon the wound site.

Abstract: Arrangements of the innovation relate to a micro-coring system configured to harvest a plurality of cores, either sequentially or simultaneously. In one arrangement, the micro-coring system comprises a harvesting tool configured to harvest and transfer at least one tissue core from a donor site to a recipient site, the at least one tissue core having a diameter of between about 1.0 mm and 3.0 mm diameter. In one arrangement, the harvesting tool comprises: a coring tool configured to penetrate tissue at the donor site and capture a tissue core from the tissue, and an extractor pin disposed within an aperture extending along a longitudinal axis of the coring tool, the extractor pin configured to extract the core from the coring tool.
