    • Products, processes, compositions, kits, and methods are provided for cartilage-derived implants. The implants can exhibit resistance to enzyme (e.g., collagenase, protease, etc.) digestion compared to the source tissue from which they were derived while still having one or more mechanical properties comparable to the source tissue from which they were derived. The implants can also have a plurality of molecular bridges between molecules of the cartilaginous material. The molecular bridges can connect one or more collagen fibrils and/or/with one or more glycosaminoglycans. The implants can also be treated with cationic detergent, packaged and sterilized with or without additional components, and surgically implanted into subjects.
    • 为软骨衍生的植入物提供产品,方法,组合物,试剂盒和方法。 与源自其衍生的源组织相比,植入物可以表现出对酶的抗性(例如,胶原酶,蛋白酶等)的消化,同时仍然具有与其来源的源组织相当的一种或多种机械性质。 植入物还可以在软骨材料的分子之间具有多个分子桥。 分子桥可以连接一个或多个胶原纤维和/或/与一种或多种糖胺聚糖。 植入物也可以用阳离子洗涤剂处理,包装和灭菌,有或没有其他成分,并手术植入受试者。

    • Biomaterials with enhanced properties such as improved strength, flexibility, durability and reduced thickness are useful in the fabrication of biomedical devices, particularly those subjected to continuous or non-continuous loads where repeated flexibility and long-term durability are required. These enhanced properties can be attributed to elevated levels of elastin, altered collagen types, and other biochemical changes which contribute to these enhanced properties. Examples of devices which would be improved by use of such tissue include heart valves, including percutaneous heart valves, and vascular grafts, patches and the like. Such enhanced materials can be sourced from specific populations of animals, such as neonatal calves, or in range-fed adult cattle, or can be fabricated or created from cell populations exhibiting such properties. In one embodiment, glutaraldehyde-fixed neonatal pericardial tissue is used to create leaflets in a percutaneous heart valve, and may be used without chemical fixation, with or without processes to remove residual cellular membranes, and utilized as a scaffold material for tissue engineering
    • 具有增强性能的生物材料,例如改进的强度,柔韧性,耐久性和减小的厚度,可用于生物医学装置的制造,特别是需要连续或非连续载荷的那些,其中需要重复的柔性和长期的耐久性。 这些增强的性质可归因于弹性蛋白水平升高,胶原蛋白类型改变,以及其他有助于这些增强性质的生物化学变化。 将通过使用这种组织来改善的装置的实例包括心脏瓣膜,包括经皮心脏瓣膜,血管移植物,贴剂等。 这种增强的材料可以来自特定动物群体,例如新生小牛,或在范围饲养的成年牛中,或者可以由表现出这种性质的细胞群体制造或产生。 在一个实施方案中,戊二醛固定的新生儿心包组织用于在经皮心脏瓣膜中产生小叶,并且可以在没有化学固定的情况下使用,具有或不具有除去残留细胞膜的方法,并用作组织工程的支架材料
