Abstract
Exemplary embodiments of apparatus and method for harvesting small portions of tissue (“micrografts”) to form grafts can be provided. For example, a hollow tube can be inserted into tissue at a donor site, where a distal end of the hollow tube can have two or more points or extensions to facilitate separation of the micrografts from the surrounding tissue. The exemplary apparatus can be provided that includes a plurality of such tubes for simultaneous harvesting of a plurality of micrografts. The harvested micrografts can have a small dimension, e.g., less than about 1 mm, or less than about 0.3 mm, which can promote healing of the donor site and/or viability of the harvested tissue. The micrografts can be approximately cylindrical or strip-shaped, and can be placed in a biocompatible matrix to form a graft or directly into tissue at the recipient site. Such exemplary micrografts can be obtained from skin or other types of tissue, e.g., various internal organs.
