Abstract
A process for the production of prostheses wherein endogenic tissue material is substantially mechanically comminuted and, if necessary, additionally enzymatically digested to tissue particles, whose sizes fall within very narrow limits. A preshaped carrier material is treated with the resultant suspension. In the case of a porous carrier material the suspension is filtered through the material, whereas with less or non-porous carrier material the suspension is applied to the material surface by centrifuging. Unlike the case of corresponding prior art processes, as a result of this improvement, the process according to the invention can be performed very rapidly, i.e., directly during the operation and in a closed system.
