collafleece®
RESORBABLE COLLAGEN FOR WOUND MANAGEMENT

wet-stable porcine collagen sponge
Natural homeostasis
Maintains integrity
collafleece® is a wet-stable, porcine collagen sponge with highly efficient hemostatic properties. Its natural porous collagen structure supports the hemostasis and controls the natural healing of the wound 1. Owing to its spongy structure, the collafleece® resorbs within ~2-4 weeks 2.
FAST HEMOSTASIS AND STABILIZATION OF THE BLOOD CLOT
The efficacy of collafleece® is based on the well-known characteristics of collagen. The process of blood clotting comprises a complex series of reactions induced by the adhesion of platelets to the collagen fibers, which results in the formation of a thrombus by platelet aggregation. The secretion of coagulation factors is thereby triggered, which initiate further reactions as the formation of a fibrin clot 3-5. The fast clotting reaction through collafleece® is particularly helpful when treating hemostatic compromised patients 1.
collafleece® is a hemostatic collagen sponge indicated to support wound healing and control bleedings.
IMPLANTOLOGY, PERIODONTOLOGY AND ORAL AND CMF SURGERY
- Protection and hemostatic treatment of minor oral wounds
- Protection of the Schneiderian membrane
- Covering of biopsy or transplant harvesting sites, as well as bone block harvesting sites
- Protection and hemostatic treatment after tooth extraction
Shaping
collafleece® can be cut to the required size with a pair of scissors before application onto the wound or insertion into the wound. Should greater amounts of fleece be required for haemostasis, the excess material must be removed before the wound is closed. Over-packing the wound with collagen should be avoided.
Fixation
A direct fixation of collafleece® by sutures or pins is not possible, but also mostly not needed. After shaping, the fleece is carefully pressed onto the wound site with a pair of tweezers until the fibrin ensures adhesion of the fleece to the wound site. An indirect fixation by cross- or holding sutures could help to keep the fleece in place when applied in extraction sockets or soft tissue harvesting sites.
Exposure
In case of a dehiscence the wound heals without complications by granulation tissue formation and free contraction. The main problem of an exposure of a collagen membrane is its fast bacterial resorption resulting in loss of the barrier function. As the intention of collafleece® is not providing a barrier but supporting wound healing and hemostasis, fast resorption in case of open healing is not a problem. Application of a collafleece® on top of a barrier membrane is recommended in unstable soft tissue situations, or for protection of the wound healing area if a wound dehiscence is expected to occur.
Rehydration
In general, the dry application of collafleece® is recommended, as rehydration can impair the hemostatic properties of the material. When placed in the defect, the blood is absorbed very quickly while the structural integrity of the material is maintained.
