  • Patent number: RE39172
    Abstract: A bicomposite material based on collagen is prepared which has two closely bound layers and is biocompatible, non-toxic, hemostatic and biodegradable in less than a month, and can be used in surgery to achieve hemostasis and prevent post-surgical adhesion. To prepare the material, a solution of collagen or gelatin, which may contain glycerine and a hydrophilic additive such as polyethylene glycol or a polysaccharide, is poured onto an inert support to form a layer 30 ?m to less than 100 ?m thick. Then a polymeric porous fibrous layer is applied during gelling of the collagen or gelatin, and the resultant material is dried. The polymeric porous fibrous layer may be made of collagen or a polysaccharide, and have a density of not more than 75 mg/cm2, a pore size from 30 ?m to 300 ?m and a thickness of 0.2 cm to 1.5 cm.
