摘要: An implantable medical device includes a porous metal foam or foam-like structure having pores defined by metal struts or webs wherein the porous structure has directionally controlled pore characteristics. The pore characteristics controlled include one or more of the metal structure porosity, pore size, pore shape, pore size distribution and strut thickness. The pore characteristics may vary in one or more directions throughout the structure. Preferably the pore characteristics are controlled to match the porous metal structure to various mechanical and biological requirements of different regions of the structure in order to optimize aspects of the implants performance and may vary not only over the surface of the porous structure but through the depth of the porous structure. The thickness of the porous metal structure may also be modified to establish a thickness profile that optimizes mechanical and biological requirements of the implants performance. Acetabular cup embodiments of the invention are described. Various methods of manufacturing implants having directionally controlled pore characteristics are described.

摘要: According to the present invention a prosthetic bearing component is formed from a composite synthetic plastics material comprising an injection molded thermoplastic polymeric matrix reinforced by a pitch based carbon fiber and having a bearing surface which has been machined with a surface roughness with a value less than Ra 2 &mgr;m. Such components have shown superior wear qualities. Preferably the bearing surface shape is machined with tolerances of 0.1 to 0.15 mm. The composite material must be capable of withstanding a radiation value of at least 2.8 Mega Rads (MRad). In components in which the bearing surface is substantially or part spherical a sphericity of 0.3 &mgr;m within a solid angle of 45° is required.

摘要: A method of producing an orthopedic implant including the steps of building a flat open model of at least a portion of an implant. The flat open model may be built using a selective laser sinter process. The flat open model preferably includes at least one groove along either a first surface or a second surface of the model. Next a force may be applied to the flat open model at predetermined locations to thereby cause the model to bend and assume a shape similar to a desired result. The now bent model may be resurfaced by either applying additional material such that the bent flat open model assumes the shape of a desired implant or the bent open model may be snap fit to an additional element.

摘要: Method of providing a desired material on at least a portion of a surface of a substrate of a component, such as a medical implant component. The method may comprise the steps of arranging the component in a holding fixture which is capable of holding the component at atmospheric or substantially atmospheric pressure, and spraying particles of the desired material at a predetermined high velocity toward the at least one portion of the surface of the substrate so as to enable a layer of the material to be accumulated thereon. The spraying may be performed at atmospheric or substantially atmospheric pressure. The desired material may be a reactive type material, such as titanium or an alloy thereof. The method may enable a high density coating or layer of the material to be provided without the use of a post spray thermal consolidation process.

摘要: A method of fabricating a porous or partially porous three-dimensional metal article for use as a tissue ingrowth surface on a prosthesis. The porous article is formed using direct laser remelting in a cross section of a layer of metallic powder on a build platform without fusing thereto. The power, speed, spot size and beam overlap of the scanning laser is coordinated so that a predetermined porosity of the metallic powder can be achieved. Laser factors also vary depending from the thickness of the powder layer, type of metallic powder and size and size distribution of the powder particles. Successive depositing and remelting of individual layers are repeated until the article is fully formed by a layer-by-layer fashion. In an additional embodiment, a first layer of metallic powder may be deposited on a solid base or core and fused thereto.

摘要: A surgical instrument includes a housing, an end effector and an elongated shaft extending therebetween. The elongated shaft includes a distal portion that is movable between aligned and articulated configurations. A pair of drive cables extends through the elongated shaft and is coupled to the distal portion such that reciprocal longitudinal motion of the drive cables induces movement of the distal portion between the aligned and articulated configurations. An articulation drive mechanism is operable to induce reciprocal longitudinal motion of the drive cables. The drive mechanism includes an actuator and a pair of torsion members that are rotatable about two distinct axes in response to movement of the actuator. A respective follower is operatively coupled to each torsion member to translate in a respective longitudinal direction in response to rotation of the torsion members, and each follower is coupled to a respective drive cable to impart translational motion thereto.
