Abstract
A surgical procedure for preparing a graft for insertion in an opening in a human body, according to which a mold is formed in the opening and transferred from the opening to a position adjacent a stylus. A contour of the mold is traced with the stylus; and the tracing movement of the stylus is transferred to corresponding movement of a cutting member so that the cutting member cuts the same contour in the graft.
