    • The present invention relates to a solid composition useful for tissue gluing, tissue sealing and haemostasis consisting essentially of a) a carrier which has at least one of the following physical properties: elasticity module in the range of 5-100 N/cm, density of 1-10 mg/cm3, chamber diameter of more than 0.75 mm and less than 4 mm and/or having a chamber diameter average below 3 mm and evenly distributed and fixed upon said carrier, b) solid fibrinogen, and c) solid thrombin. The carrier is a biodegradable polymer such as a polyhyaluronic acid, polyhydroxy acid, e.g. lactic acid, glucolic acid, hydroxybutanoic acid, a cellulose, gelatine or collagen, such as a collagen sponge, e.g. a collagen sponge consisting essentially of collagen type I fibres. The fibrinogen and thrombin are preferably human, purified form a natural source, or transgenic or recombinant human fibrinogen and/or thrombin. In a preferred embodiment the composition does not comprise any antifibronolytic agent such as aprotinin, ε-aminocaproic acid or α2-antiplasmin.
    • 本发明涉及用于组织胶粘,组织密封和止血的固体组合物,其基本上由a)具有以下物理性质中的至少一种的载体:弹性模量在5-100N / cm的范围内,密度 1-10毫克/立方厘米,室直径大于0.75毫米,小于4毫米,和/或室直径平均值低于3mm,均匀分布和固定在载体上,b)固体纤维蛋白原,和c)固体凝血酶 。 载体是可生物降解的聚合物,例如多透明质酸,多羟基酸, 乳酸,葡萄糖酸,羟基丁酸,纤维素,明胶或胶原,例如胶原海绵,例如胶原蛋白。 基本上由I型胶原纤维组成的胶原海绵。 纤维蛋白原和凝血酶优选为人,从天然来源或转基因或重组人纤维蛋白原和/或凝血酶纯化。 在优选的实施方案中,组合物不包含任何抗纤维蛋白溶解剂,例如抑肽酶,μ-氨基己酸或±2-抗血浆素,
