Coating for an implant
The present invention relates to an implant comprising an implant body having a first surface area configured for contact with soft connective tissue and a second surface area configured for contact with bone tissue, wherein the first surface area is covered with a coating comprising tantalum and the second surface area is formed by a material, which is different than the one forming the coating.
Artificial joint cup
An artificial joint cup, in particular a hip joint cup, for implanting in a cavity in a bone. The joint cup is, in particular, substantially in the form of a spherical dome cup, having a convex outer surface and a concave inner surface. In addition, the joint cup comprises an outer diameter and an inner diameter. The ratio of the difference between the outer diameter and the inner diameter, in relation to the outer diameter, is in a range of between 0.5 and 0.07, preferably between 0.3 and 0.075, particularly preferably between 0.2 and 0.1. The joint cup is manufactured from a ceramic material, and the convex outer surface has a micro-structuring.
Femoral component for a knee prosthesis with improved articular characteristics
An orthopaedic knee prosthesis includes a femoral component which exhibits enhanced articular features, minimizes removal of healthy bone stock from the distal femur, and minimizes the impact of the prosthesis on adjacent soft tissues of the knee.
FEMORAL AUGMENTS FOR USE WITH KNEE JOINT PROSTHESIS
A femoral augment, or set of augments, for use with a knee joint prosthesis, where the femoral augment includes a main body portion, an aperture formed within the main body portion and extending in a generally distal/proximal direction, and a pair of legs extending outwardly from said main body portion in a generally posterior direction. In the preferred embodiment, the aperture is configured to receive a stem extension implant, and to allow it to pass through. Additionally, the legs of the femoral augment are preferably configured to be seated proximal of a proximal side of a pair of condylar portions of a femoral component of a knee joint prosthesis. The present invention is intended for situations in which the distal portion of the femur is defective, and it provides a method and devices that allow for preservation of healthy peripheral bone, while still providing the necessary augmentation to the distal portion of the femur.
SURFACE COATING FOR A MEDICAL INSTRUMENT, MEDICAL INSTRUMENT HAVING A SURFACE COATING, AND METHOD FOR PRODUCING A SURFACE COATING FOR A MEDICAL INSTRUMENT
A surface coating for a medical instrument includes an interference filter having at least one dielectric layer and at least one metallic layer arranged one above another. At least one of the at least one metallic layer and the at least one dielectric layer is adapted to be structurally altered by action of a corrosive environment on the surface coating such that the surface coating is convertible from a first state to a second state. In the first state, the surface coating has a first spectral reflectivity. In the second state, the surface coating has a second spectral reflectivity that is different from the first spectral reflectivity.
Femoral implant systems
A femoral augment, or set of augments, for use with a knee joint prosthesis, where the femoral augment includes a main body portion, an aperture formed within the main body portion and extending in a generally distal/proximal direction, and a pair of legs extending outwardly from said main body portion in a generally posterior direction. In the preferred embodiment, the aperture is configured to receive a stem extension implant, and to allow it to pass through. Additionally, the legs of the femoral augment are preferably configured to be seated proximal of a proximal side of a pair of condylar portions of a femoral component of a knee joint prosthesis.
POROUS STRUCTURE FOR BONE IMPLANTS
A bone implant includes a body having a porous structure and having a size and shape configured for fitting to a bone, preferably in a bone defect. The porous structure is comprised of regularly arranged elementary cells whose interior spaces form interconnected pores, the elementary cells are formed by basic elements arranged in layers, wherein the basic elements are shaped like tetrapods, the tetrapods in each layer being arranged in parallel orientation and being positioned in-layer rotated with respect to tetrapods of an adjacent layer. The layers with rotated and non-rotated tetrapods are alternatingly arranged. Thereby a porous structure can be achieved which features improved mechanical characteristics, leading to improved biocompatibility.
Nanostructure Surface Coated Medical Implants and Methods of Using the Same
Compositions including a surface or film comprising nanofibers, nanotubes or microwells comprising a bioactive agent for elution to the surrounding tissue upon placement of the composition in a subject are disclosed. The compositions are useful in medical implants and methods of treating a patient in need of an implant, including orthopedic implants, dental implants, cardiovascular implants, neurological implants, neurovascular implants, gastrointestinal implants, muscular implants, and ocular implants.
Coating process for non-conductive substrates and devices made from the coating process
A method for manufacturing a surgical implant. A metal layer is deposited onto a polyaryletherketone (PAEK) substrate by generating a series of pulses using a high power impulse magnetron sputtering process. Each pulse is applied in a series of micro pulse steps comprising (i) micro pulse on steps ranging from 10 s to 100 s and (ii) micro pulse off steps ranging from 5 s as to 400 s; at a repetition frequency ranging from 50-2000 Hz with 2 micropulses to 20 micropulses per repetition, a total pulse on time ranging from 25 s to 800 s for 5 minutes to 300 minutes at averaged power ranging from 200 W to 3000 W. The series of pulses are performed in a unipolar mode or a bipolar mode.
IMPLANTS WITH FRANGIBLE FASTENER PORT PLUGS AND METHODS OF MANUFACTURING IMPLANTS WITH FRANGIBLE FASTENER PORT PLUGS
An orthopedic implant can comprise a structural body, a plug and a frangible connection. The structural body can comprise a first surface, a second surface opposing the first surface, and a through-bore extending from the first surface to the second surface. The through-bore can have a bore surface. The structural body can be formed of a porous material. The plug can be disposed in the through-bore. The frangible connection can link the bore surface and the plug. A method of manufacturing an orthopedic implant can comprise producing a porous structural body having a port, producing a plug for positioning in the port, and producing a plurality of frangible crosspieces within the port to connect the plug to the structural body.
