Gesinterter Formkörper mit poröser Schicht auf der Oberfläche sowie Verfahren zu seiner Herstellung

Porous coatings on high-performance ceramics attempt to combine the mechanical and thermal characteristics, which fulfil stringent demands, of the substrate material with the advantageous properties of coating materials. The subsequent application of layers of this type to the pre-sintered substrate produces unsatisfactory results in several areas of use with regard to possible layer thickness, porosity and adhesion. According to the invention, a shaped body consisting of a sintered, inorganic material, whose surface comprises a porous layer is produced in such a way that the base body is first formed as a green body. A layer in the form of a suspension, also containing an inorganic material, is then applied to the surface or to one section of the surface of the base body. A predetermined fraction of a pore-forming substance is mixed with at least the material of said layer and the green body with its applied layer is subjected to the thermal treatments required for producing a monolithic ...

CERAMIC PROSTHESIS

Surgical implant

A method of making a surgical implant includes diffusion bonding to a surface of a substrate of a biocompatible material (eg titanium, titanium alloy, or cobalt-based alloy,) a mesh-form sheet material of e.g titanium, titanium alloy, or cobalt-based alloy so that there is provided on the surface a porous coating into which bone tissue can grow or surgical cement can enter.

Biomedical implant

The invention relates to a substrate comprising a bioactive element and a method to obtain the substrate with the bioactive element. The plate comprising the bioactive element relies upon formation of a carbonate layer containing biologically relevant and active ions on a surface of the substrate. The substrate is pure titanium or a titanium alloy. Alternatively any substrate may be used if it has been coated with a titanium based coating. Following cleaning of the substrate, it is immersed in an alkali solution, such as sodium or potassium hydroxide. This forms a titanate surface structure of below 10 micrometre thickness. Alternatively a layer of crystalline titanium dioxide may be coated on the substrate. The substrate is then rinsed with water and cleaned before being immersed in a salt solution for 1-14 days at 60ºC. This results in ion-exchange in the titanate surface and the formation of a carbonate coating on the surface. The salt solution used may be strontium acetate (Sr-acetate ...

The stem is configured to be inserted into the aperture, has a proximal portion and a longitudinal axis. The shape memory material within the proximal portion has a cross-section perpendicular to the longitudinal axis. At least a portion of the shape memory material within the proximal portion is in a compressed state by application of a plurality of compressive forces at a temperature below an austenitic finish temperature of the shape memory material so that the cross-section expands through shape memory effect via the formation of austenite in response to a temperature increase after insertion into the aperture thereby causing a locking-force to be exerted against an inner surface of the aperture, the locking force being sufficient to stabilize the implant in the aperture.

Two-component artificial disc replacements

Artificial disc replacements (ADRs) and total disc replacements (TDRs) are based upon two, directly articulating components, resulting in a restricted-motion system that better approximates more normal spinal flexion, extension, and lateral bending. One component may have a concave articulating surface, and the other a convex articulating surface. The radius of curvature of the articulating surface may be smaller in the anterior-to-posterior direction of the ADR than the radius of curvature of the articulating surface in the left-to-right direction of the ADR. Both components are preferably made of a hard material and are highly polished to reduce friction.

One detailed system is completely surgically implantable in the patient such that no part of the system is external to the patient while the system is in use. In addition, externally controlled devices are provided which allow for modulation of implanted components.

Interbody Cage for Spinal Fusion and Method of Implanting Interbody Cages into Spines

A spinal interbody fusion implant has an impact rod fitting that is configured and adapted to be connected to an impact rod during implantation of the implant.

Porous coatings for orthopedic implants

A high-purity porous metal coating is formed over a substrate by thermal spraying a metal coating material over the desired portion of the substrate in an atmospheric air environment. The metal coating material may react with the atmosphere to cause impurities in the applied coating. The impurity-rich portion of the applied coating is subsequently removed to form the high-purity porous metal coating. Process steps are included that cause the impurity-rich portion of the applied coating to be a surface portion that is removable to arrive at the high-purity coating. A protective shroud may be used to limit the amount of impurity imparted to the applied coating and/or a getter material may be employed to continually bring impurities toward the surface of the coated substrate during coating.

Arthroplasty Instruments and Associated Method

A reamer for use in performing arthroplasty includes a first cutting structure having an inner concave surface that defines a first cavity and terminates in a generally circular leading edge. The inner concave surface includes a first cutting feature that is spaced apart from the leading edge. An elongate member extends from the first cutting structure into the first cavity toward the leading edge that includes a second cutting feature. A second cutting structure is secured to the elongate member and positioned within the first cavity.
