Non-glutaraldehyde fixation of an organ or a prosthesis for implantation in a mammal is based upon carbodiimide treatment. An aqueous solution containing a coupling agent, such as EDC, in combination with a coupling enhancer, such as sulfo-NHS, and a high concentration of a diamine cross-linking agent is used. As a result, only minimal surface reduction occurs during fixation, and the resultant products show a dramatic increase in resistance to calcification. |
