In order to achieve a reproducible treatment for materials of biological origin such as membranes, skins, vessels, heart valves, tendons and ligaments and, in particular, collagen materials, hydrophobic accompanying substances are, first of all, chemically removed without the accompanying substances being chemically altered. Non-hydrophobic accompanying substances are subsequently removed. The materials treated in this manner are used to form membranes, heart valves or vessels or are further processed to form solutions, fibers, fiber weaves, fibrous tissues or sponges and are optionally populated with cells and/or used for carrying out controlled tissue regeneration. |
