Nitinol alloys (Nitinol) exhibit a dramatically enhanced elasticity, known as "superelasticity", which is becoming integral to the design of a variety of new medical products. Elasticity is the most apparent of the advantages afforded by this material, but by no means the only or most important. Also discussed in this paper are features such as biocompatibility, kink resistance, constancy of stress, physiological compatibility, shape memory deployment, dynamic interference and fatigue resistance. Each of these properties is discussed and highlighted through example. Examples presented include stents, filters, retrieval baskets, and surgical tools.
镍钛诺合金（Nitinol）展现出显著增强的弹性，即所谓的“超弹性”，这正成为各种新型医疗产品设计中不可或缺的一部分。弹性是这种材料最明显的优势，但绝不是唯一或最重要的优势。本文还讨论了生物相容性、抗扭结性、应力恒定性、生理相容性、形状记忆展开、动态干涉和抗疲劳性等特性。通过实例对这些特性中的每一项进行了讨论和强调。所举实例包括支架、过滤器、回收篮和手术工具。
