Biologic absorbable implant material for filling and closing soft tissue cavities and method of its preparation

摘要

There is disclosed a biologic absorbable implant material for filling and closing soft-tissue cavities and for replacing soft-tissue parts, and a method of its preparation. The implant material consists essentially of bone tissue of human or animal origin, is decalcified, and the original protein content of the osseous hard substance is unchanged. By cross-linking of these native proteins with a cross-linking agent, a high elasticity, a good stability and a marked memory-effect are attained. The method for the preparation of the implant material includes degreasing, decalcification and cross-linking of the available proteins and then drying and sterilizing of the material.
