Abstract
In one aspect, the present disclosure relates to a method for harvesting biological tissue. In some embodiments, the method includes providing a device having a plurality of segments of hollow tubes, each hollow tube having at least one point at the distal end of the hollow tube, the plurality of segments forming a two dimensional array of hollow tubes, wherein each segment can include a plurality of hollow tubes; positioning the two dimensional array of hollow tubes proximal to an upper surface of a biological tissue; advancing a first segment of the two dimensional array of hollow tubes into the biological tissue to sever portions of the biological tissue from the surrounding tissue; raising the first segment of the two dimensional array of hollow tubes such that the biological tissue remains in each of the hollow tubes of the first segment; advancing a second segment of the two dimensional array of hollow tubes into the biological tissue to sever portions of the biological tissue from the surrounding tissue; and raising the second segment of the two dimensional array of hollow tubes such that the biological tissue remains in each of the hollow tubes of the second segment.
