The formation of a stable blood clot is important for wound healing. When an open-pored collagen sponge is used, the outstanding hemostatic properties of collagen are at the forefront. Modern collagen sponges act as an initial matrix for tissue healing over the course of healing. The blood clot is stabilized in the defect and the subsequent steps in wound healing can proceed undisturbed.The special feature of sponge-like collagen products is their ability to absorb many times their own weight in fluid without changing their spatial dimensions. This means that they do not create any pressure or swelling in the defect.The delicately interwoven collagen fleece preserves and stabilizes the blood clot, acts as a matrix for migrating cells, and supports the generation of new tissue.
