摘要： A prosthetic hip joint includes a ceramic hip head having a bore which defines a surface, wherein the bore surface has a layer of malleable material disposed on at least a portion thereof. The surface of the bore includes surface imperfections in the form of peaks and valleys. The prosthetic hip joint can also include a femoral component having a trunnion with a tapered surface adapted for friction fit insertion into the bore of the hip head. The layer of material, such as pure titanium, distributes a load on the joint reducing localized stress points produced by opposing asperity peaks in the load-bearing surfaces of the bore and trunnion.

摘要： A prosthesis is provided having at least a smooth non-articulating load bearing surface disposed adjacent a bone. The prosthesis includes a substrate formed from a metallic alloy. At least the regions of the substrate defining the load bearing surface are coated with a biologically inert abrasion resistant material harder than the substrate for preventing leaching of ions from the substrate into adjacent body tissue and for preventing wear. The coating may be titanium nitride or zirconium or other such material exhibiting biological inertness and acceptable hardness. The coating preferably defines a thickness of 8-10 microns.

摘要： The invention provides hard, wear resistant, biocompatible and blood compatible coatings for components of ventricular assist (Figs. 5A-5B), external mechanical heart and blood flow assist devices and total heart implants (Figs. 1-4B) that are exposed to conditions of wear in the body and that may be exposed to blood components. The components are 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.

摘要： Medical 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 hemiarthroplasty applications such as unipolar artificial joints, including unipolar hip joints or surface replacements, knee joints, shoulder joints, elbows, spinal segments, fingers, etc. The zirconium oxide or nitride coated prostheses also provide a barrier against implant corrosion caused by galvanic coupling with other metal components or in vivo ionisation of the metal prosthesis.

摘要： The invention relates to an implant that is to be inserted into a human or animal body and comprises at least one implant part. Said at least one implant part is provided with a base which is made of an implant material and has a surface that is embodied at least in part in the form of an artificial joint surface. Some or all of the joint surface is covered with a wear-reducing hard material coating. In order to improve said implant so as to extend the service life and increase the compatibility thereof, an intermediate layer is provided between the hard material coating and the at least one joint surface that is made of the implant material in order to reduce tensions between the hard material coating and the implant material. Also disclosed is an improved method for producing an implant that is to be inserted into a human or animal body.

摘要： A device (2) is disclosed for introducing a flexible elongated element through at least two portions of a subject. In a preferred embodiment, the device includes a proximal end and a distal end, and an advancement unit (300) for longitudinally advancing the flexible elongated element toward the distal end of the device (2) such that a proximal end of the elongated element may exit from the distal end of the device with sufficient force to pass through the subject. The device also includes a curved die (204) at the distal end of the device (2) for imparting a looping configuration to portions of the flexible elongated element exiting the distal end of the device (2), and a curved guide at the distal end for receiving the looped flexible elongated element as it returns to the distal end of the device. In a further feature of the invention, a cutting mechanism (206) is provided to permit the looped flexible elongated element to be separated from the remainder of the flexible elongated element. And in a further feature of the invention, the cutting mechanism (206) is adapted to deform the trailing end of the looped flexible elongated element so that the trailing end is forced distally, toward the subject being sutured.
