Abstract: An ankle support for protecting an injured or uninjured ankle which includes lateral support members having a flexion region operable to limit plantar and dorsal flexion to 40 degrees. Lateral support members are connected with lower-leg supports which together act to limit rotation to 15 degrees and medial and lateral bending to 10 degrees. Ankle support is preferably contoured with a low component-profile such that ankle support can be worn within a shoe to provide user with support and stabilization during rigorous activity. Adjustable straps are utilized to firmly engage ankle support with user's lower leg which operably reduces or minimizes load to the foot. Ankle support component parts are preferably formed from a low melting temperature thermo-forming polymer, polymer alloy, or composite material which provides the user with an advantageous ankle support and method for maintaining ankle supports fit to the lower leg.

Abstract translation: 用于保护受伤或未受伤的脚踝的脚踝支撑，其包括具有可操作以将足底和背屈屈曲限制到40度的屈曲区域的侧向支撑构件。 横向支撑构件与小腿支撑连接，它们一起起作用以将旋转限制在15度，内侧和外侧弯曲到10度。 踝关节支撑件优选具有低的部件轮廓，使得脚踝支撑件可以穿在鞋中以在严格活动期间为使用者提供支撑和稳定。 可调节带被用来牢固地接合脚踝支撑件与使用者的小腿，其可操作地减小或最小化对脚的负荷。 踝支撑部件优选地由低熔点温度的热成型聚合物，聚合物合金或复合材料形成，其为使用者提供了一种有利的脚踝支撑和用于维持与小腿配合的踝部支撑的方法。

Abstract: Cardiovascular and other medical implants fabricated from low-modulus Ti--Nb--Zr alloys to provide enhanced biocompatibility and hemocompatibility. The cardiovascular implants may be surface hardened by oxygen or nitrogen diffusion or by coating with a tightly adherent, hard, wear-resistant, hemocompatible ceramic coating. The cardiovascular implants include heart valves, total artificial heart implants, ventricular assist devices, vascular grafts, stents, electrical signal carrying devices such as pacemaker and neurological leads, defibrillator leads, and the like. It is contemplated that the Ti--Nb--Zr alloy can be substituted as a fabrication material for any cardiovascular implant that either comes into contact with blood thereby demanding high levels of hemocompatibility, or that is subject to microfretting, corrosion, or other wear and so that a low modulus metal with a corrosion-resistant, hardened surface would be desirable.

Abstract: Stents fabricated from a substrate of a low modulus metal coated with blue to black zirconium oxide or zirconium nitride. The coating provides enhanced thrombogenicity, biocompatibility, blood compatibility, corrosion-resistance, friction and microfretting resistance, durability, and electrical insulation, where applicable. The coatings may be applied to low modulus metallic substrates by physical or chemical vapor deposition as well as other ion-beam assisted methods. Preferably, however, for optimizing attachment strength, the stents are fabricated from zirconium or zirconium-containing alloys and the coatings are formed by oxidizing or nitriding through an in situ method that develops a coating from and on the metal surface of the stent, without need for depositing a coating on the metal surface.

Abstract: An annuloplasty ring fabricated from a component of a low elastic modulus metal coated with blue to black zirconium oxide or yellow to orange zirconium nitride. The coating provides enhanced thrombogenicity, biocompatibility, hemocompatibility, corrosion-resistance, friction and microfretting resistance, durability, and electrical insulation. The coatings can be applied to the underlying low modulus metallic components by physical or chemical vapor deposition as well as other ion-beam assisted methods. Preferably, however, for optimizing attachment strength, the annuloplasty ring components are fabricated from zirconium or zirconium-containing alloys and the coatings are formed by oxidizing or nitriding through an in situ method.

Abstract: Hard, wear resistant, biocompatible and blood compatible coatings for components of external blood-contacting pumps including mechanical heart devices that are exposed to conditions of wear in the body and that may be exposed to blood components. The components may be fabricated from zirconium or the alloys of zirconium and the coatings comprise either blue-black or black zirconium oxide or zirconium nitride that are tightly adhered to the underlying metal substrate. In the event that the component is used under conditions which subject it to wear, then the coating should have a thickness that provides sufficient residual compressive stresses to withstand these conditions.

Abstract: A novel coated prosthesis that can be tailored to avoid the problem of bone resorption caused by stress shielding. The permanent, load-bearing skeletal replacement prosthesis is coated or covered with a bioabsorbable polymer at selected sites on its surface so that bone affixation is preferentially delayed at these covered sites and bone adjacent to uncoated areas are not stress shielded. Thus, resorption is avoided. When the bioabsorbable polymer is gradually absorbed away, bone affixation takes place on the exposed surfaces, as needed.

Abstract: Orthopedic implants of zirconium or zirconium-based alloy coated with blue or blue-black zirconium oxide or zirconium nitride to provide low friction, highly wear resistant coatings especially useful in artificial joints, such as hip joints, knee joints, elbows, etc. The invention zirconium oxide or nitride coated prostheses are also useful to reduce microfretting wear in multi-component surgical implants subject to such wear. Further, the coatings provide a barrier against implant corrosion caused by ionization of the metal prosthesis. Such protection can be extended by the use of oxidized or nitrided porous coatings of zirconium or zirconium alloy beads or wire mesh into which bone spicules may grow so that the prosthesis may be integrated into the living skeleton.

Abstract: Orthopedic implants of zirconium or zirconium-based alloy coated with zirconium oxide to provide low friction, highly wear resistant coatings especially useful in artificial joints, such as hip joints, knee joints, elbows, etc. The invention zirconium oxide coated prostheses are also useful in that the zirconium oxide coatings provide a barrier against implant corrosion caused by ionization of the metal prosthesis. Such protection can be extended by the use of oxidized porous coatings of zirconium or zirconium alloy beads or wire mesh into which bone spicules may grow so that the prosthesis may be integrated into the living skeleton.
