摘要： A modular mating stent is adapted to resist migration within a receiving stent. The modular mating stent has a substantially self-expandable first section of predetermined compressibility that is adapted to permit the first section to conform to the shape of a body lumen surrounding the first section. The modular mating stent also has a balloon-expandable second section that is less compressible than the first section, which is adapted to firmly engage a surface of the receiving stent surrounding the second section.

摘要： A method for arthroplasty includes using a self-locking prosthesis that has a member structured to transfer a load produced by the weight of a patient to a bone. An expandable bone-locking portion that is integral to the member includes a shape-memory material and expands to produce a locking force. A portion of the bone is removed to form an aperture in the bone. The bone-locking portion is inserted into the aperture, and a temperature increase causes a change from a contracted state to an expanded state resulting in expansion of the bone-locking portion so as to contact the inner surface. The expanding is sufficient to create a locking force at the junction between the inner surface and the bone-locking portion of the prosthesis and the majority of the locking force is applied at or above the metaphysis. The length/width ration of the prosthesis may be less than or equal to 5. The resulting reconstructed long-bone may have improved primary and long-term stability.

摘要： A damping and shock absorbing method and apparatus for permanent or non-permanent use in the human body and having a shape memory alloy material cycled through stress-strain hysteresis to dissipate energy for effective damping. A sufficiently high pre-stress is applied to the damping element(s) to ensure that the damping working range is within the superelastic cycle. The damping apparatus can work in tension or compression or both in tension and compression. Moreover, damping elements from a shape memory alloy can also work in flexion and extension as well in rotation. The damping apparatus can have a stroke and force suitable for use in the human body by the design, the structure and the chemical composition of the shape memory alloy and their pre-set properties, such as plateau stresses of the superelastic cycle depend on the ambient temperature, the force of damping elements can also be changed in-situ by changing the temperature of the damping elements. The damping elements made out of a shape memory alloy can be combined with elastic elements made out of other materials to achieve stress-strain behavior more suitable for use in the individual human body.
摘要翻译：一种用于人体永久性或非永久性使用的阻尼和冲击吸收方法和装置，具有通过应力 - 应变滞后循环的形状记忆合金材料，以耗散能量以进行有效阻尼。对阻尼元件施加足够高的预应力以确保阻尼工作范围在超弹性循环内。阻尼装置可以在张力或压缩状态下工作，或者在张力和压缩状态下均可。此外，来自形状记忆合金的阻尼元件也可以在弯曲和延伸以及旋转中起作用。阻尼装置可以通过形状记忆合金的设计，结构和化学成分以及它们的预设性质（例如超弹性循环的平台应力）取决于环境，具有适合用于人体的冲程和力温度，阻尼元件的力也可以通过改变阻尼元件的温度就地改变。由形状记忆合金制成的阻尼元件可以与由其它材料制成的弹性元件结合，以实现更适合用于个体人体的应力 - 应变行为。

摘要： The object of this invention is to provide a stent for high frequency thermotherapy, which is fabricated by knitting first superlastic shape-memory alloy wires as a way to allow the first supereleastic shape-memory alloy wires to cross each other at different positions to make hollow cylindrical stent body having a net structure with a plurality of meshes. The stent body is covered with an insulating substance. A hollow cylindrical conductive body surrounds a waist part of the stent body while any one end or both ends of the conductive body is attached to the waist part of the stent body. At this time, the conductive body is fabricated by knitting second superelastic shape-memory allow wires as a way to allow the second superelastic shape-memory alloy wires to cross each other at different positions.

摘要： Medical devices may be made of shape-memory materials portions of which have been heat treated to exhibit spatial variations in the stiffness of the material. Devices including stents, vena cava filters and guidewires may be constructed from such materials. Devices may also be made from shape-memory materials which have been locally heat treated such that the superelasticity of the treated portion is destroyed while the remainder of the shape-memory material can transition between the martensitic and austenitic states.

摘要： An implantable expandable medical device in which selected regions of the device are in a martensite phase and selected regions are in an austenite phase. The martensitic regions exhibit pseudoplastic behavior in vivo and may be deformed without recovery under in vivo body conditions. In contrast the austenitic regions exhibit superelastic behavior in vivo and will recover their pre-programmed configuration upon deformation or release of an applied strain
