    • PROBLEM TO BE SOLVED: To provide a cross-linked collagen implant having improved volume stability ("sustention"), useful for correction and orthopedic surgery of a deep layer of skin.SOLUTION: The cross-linked collagen implant material includes a cross-linked collagen filler composition which is manufactured by a method including the steps of: incubating a collagen selected from the group consisting of I-type collagen, II-type collagen, III-type collagen, IV-type collagen, V-type collagen, telo-containing collagen, atelocollagen, derivatized collagen, and a combination thereof, in a suspension or solution having a pH in the range of pH 2 to 5 or pH 9 to 12, so as to form into a micro or non-fibril collagen; treating the collagen with a cross-linking agent selected from the group consisting of carbodiimide, polyaldehyde, polysulfone, activated PEG, epoxide, imidazole and diisocyanate, in particular with glutaric aldehyde, at pH 2 to 5 or pH 9 to 12; and isolating the cross-linked collagen.
    • 要解决的问题:提供具有改善的体积稳定性(“维持”)的交联胶原植入物,其可用于深层皮肤的矫正和矫形手术。解决方案:交联胶原植入材料包括交联的 胶原填充剂组合物,其通过以下方法制造:包括以下步骤:孵育选自I型胶原,II型胶原,III型胶原,IV型胶原,V型胶原, 含有胶原蛋白,胶原蛋白,衍生胶原蛋白及其组合,在pH为2至5或pH 9至12范围内的悬浮液或溶液中,以形成微或非原纤维胶原蛋白; 用选自碳二亚胺,多醛,聚砜,活化的PEG,环氧化物,咪唑和二异氰酸酯,特别是戊二醛的交联剂在pH2至5或pH9至12下处理胶原蛋白; 并分离交联胶原蛋白。
