Abstract
An apparatus and method are disclosed for marking the proper location of incisions to be made during a surgical procedure. The apparatus includes a member for penetrating inward of the outermost layer of the epidermis. A reservoir supplies a marking agent so that as the penetrating member penetrates the epidermis, marking agent is left inward of the outermost surface of the epidermis, thereby leaving a line which may be followed when making incisions during surgery. The method includes penetrating the outermost layer of the epidermis and leaving marking agent inward of the outermost layer of the epidermis. In a preferred embodiment of the method, a temporary marking agent, such as methylene blue, is used so that the line quickly disappears after surgery.
