    • The present invention relates to collagenous membranes produced from amnion, herein referred to as a collagen biofabric. The collagen biofabric of the invention has the structural integrity of the native non-treated amniotic membrane, i.e., the native tertiary and quaternary structure. The present invention provides a method for preparing a collagen biofabric from a placental membrane, preferably a human placental membrane having a chorionic and amniotic membrane, by decellularizing the amniotic membrane. In a preferred embodiment, the amniotic membrane is completely decellularized. The collagen biofabric of the invention has numerous utilities in the medical and surgical field including for example, blood vessel repair, construction and replacement of a blood vessel, tendon and ligament replacement, wound-dressing, surgical grafts, ophthalmic uses, sutures, and others. The benefits of the biofabric are, in part, due to its physical properties such as biomechanical strength, flexibility, suturability, and low immunogenicity, particularly when derived from human placenta.
    • 本发明涉及由羊膜制成的胶原膜,本文称为胶原生物制品。 本发明的胶原生物制品具有天然未处理的羊膜的结构完整性,即天然的三级和四级结构。 本发明提供了通过使羊膜脱细胞从胎盘膜,优选具有绒毛膜和羊膜的人胎盘膜制备胶原蛋白生物制剂的方法。 在优选的实施方案中,羊膜完全脱细胞。 本发明的胶原蛋白生物制剂在医疗和外科领域中具有许多用途,包括例如血管修复,血管的构造和替换,腱和韧带置换术,伤口敷料,手术移植物,眼用途,缝合线等 。 生物制品的优点部分是由于其物理性质如生物力学强度,柔韧性,可渗透性和低免疫原性,特别是当衍生自人胎盘时。
