    摘要: Fibrous connective tissue for surgical implantation is made substantially antigen-free by contact with one or more extraction agents. Solutions or mixtures of molecules having bipolar regions act as antigen removing permeation enhancers. Cationic, anionic, non-ionic or amphoteric surfactants are suitable bipolar permeation enhancers. One or more extraction agents can be combined to form extraction mixtures.

    摘要: A milling apparatus is disclosed which includes a milling machine having a milling cutter which is sealingly isolated from the milling machine within an enclosed work area, a support fixture disposed within the enclosed work area for supporting a work piece, and a mechanism for moving the milling cutter along a predetermined path relative to the work piece. Preferably, the milling apparatus is employed to cut bone into small fragments for subsequent utilization, and the sealed isolation of the milling cutter inhibits cross-contamination between differing work pieces.
