    implanting the body so that said skirt is below the dermis and in contact with but without penetration of subcutaneous tissue and the other end of the body is extracutaneous;

    leaving the body in situ until epidermal cells around the body invaginate and migrate to the collagen that forms in the bed material to provide a biological seal around the body;
