| 20090082866 | ENDOPROSTHESIS COMPONENT - An endoprosthesis component and a method for producing an endoprosthesis component is disclosed. The endoprosthesis component comprises a body predefining the shape of the endoprosthesis component. On surface portions with which the endoprosthesis component in the implanted state is in contact with human tissue, the body is covered with an outer layer which comprises a nitride, an oxynitride or an oxide based on a refractory metal and which contains silver and/or copper. An intermediate layer is arranged between the outer layer and the body in such a way that parts of the intermediate layer are accessible from the outside. The endoprosthesis component enables generation of a long-term antimicrobial action with the outer layer and, in addition, action on the surrounding tissue from the intermediate layer. | 03-26-2009 |
| 20090182341 | INSTRUMENT SET FOR FITTING AN INTERVERTEBRAL JONT PROSTHESIS - An instrument set for fitting an intervertebral prosthesis includes a guide device for an instrument or a prosthesis part, which guide device is to be secured on at least one vertebral body. In order to attach the guide device precisely on the vertebral bodies despite difficult operating conditions, an adjustment instrument is provided which positions the guide device when this is being arranged on the vertebral body. This adjustment instrument may include an intervertebral plate which is fitted into the intervertebral space so as to be positioned exactly in relation to the vertebral bodies. | 07-16-2009 |
| 20100198355 | ANKLE-JOINT ENDOPROSTHESIS - An endoprosthesis for replacing the ankle joint includes a lower component which is configured to be connected to the ankle bone, an upper component which is configured to be connected to the shin bone, and an intermediate part which forms a slide joint both with the lower and upper components. The intermediate part, which is wedge-shaped in sagittal section, is provided in order to compensate for anatomical or surgical irregularities. The upper component can also be wedge-shaped in frontal or sagittal section. | 08-05-2010 |
| 20110127700 | METHOD FOR PRODUCING A CERAMIC COMPONENT - The invention relates to a method for producing a ceramic component. With the method, a ceramic base material in powdered form and a mold having the shape of the ceramic component are provided. The ceramic base material is introduced into the mold. The ceramic component is presintered at a temperature between 880° C. and 980° C. and is then removed from the mold. The surface of the ceramic component is treated with a blasting material and the ceramic component is sintered at a temperature that is higher than the presintering temperature. With the method according to the invention, ceramic components having higher surface roughness can be produced. Due to the higher surface roughness it is easier to apply a firmly adhering coating to the ceramic component. | 06-02-2011 |
| 20110130837 | Intervertebral Implant - An intervertebral implant for insertion into an intervertebral disc space having a contact face for connection to an adjacent vertebral body. The contact face has a porous coating that allows bone tissue ingrowth into the porous coating to form an intimate connection between the contact face and the bone tissue. Rounded teeth are provided that protrude above the contact face and the porous coating and have a radius of not less than 0.1 mm. The rounded teeth do not penetrate through the bone tissue but merely compact the bone tissue. The teeth provide fixation in the bone tissue even without intimate connection to the bone tissue. A method of securing the implant in the intervertebral space with easy removal in the event of a replacement is also disclosed. | 06-02-2011 |
| 20110152953 | SURGICAL GUIDE INSTRUMENT AND METHOD FOR WORKING THE ARTICULAR PROCESSES OF VERTEBRAL BODIES - A surgical guide instrument for use on the articular processes of vertebral bodies. At the distal end of the guide instrument, there are two plier heads, which are designed for a plier movement relative to each other. A guide rail is provided, which defines a guide axis for a reamer. The guide rail is pivotable about a first pivot axis, such that the guide axis, with the pivoting movement about the first pivot axis, spans a work sector, and such that the work sector intersects an imaginary connecting line between the plier heads. | 06-23-2011 |
| 20110160858 | ENDOPROSTHESIS HAVING A PLUG-IN CONNECTION AND IMPROVED ROTARY PROTECTION - The invention relates to an endoprosthesis, particularly for the at least partial replacement of a long bone, comprising a plug-in connection for connecting a shaft ( | 06-30-2011 |
| 20110190900 | HIP-JOINT PROSTHESIS WITH A SHAFT TO BE INSERTED INTO THE FEMUR - A hip-joint prosthesis includes a shaft which is configured to be inserted into the femur and whose surface has an osteoinductive finish. This finish is provided exclusively in the metaphyseal portion of the shaft and laterally from the line delineating the maximum antero-posterior dimension of the shaft cross section. This ensures a better involvement of the metaphyseal spongiosa in the flow of forces, without compromising the ability to perform follow-up surgery on the prosthesis. | 08-04-2011 |

| 20090155855 | COVER FOR SAMPLE WITH HOMOGENOUS PRESSURE APPLICATION - The present invention relates to means for covering one or more sample(s) that are suitable to avoid or minimize evaporation and/or condensation of any vaporizable substance that may be present in the sample(s) or reaction mixture(s), in particular evaporation of substance at the fringes of a vessel or an array of vessels or condensation of said substance on the lid of a reaction vessel or a plate/block containing the sample(s) and/or the means for covering. This is achieved by providing a device comprising, among others, a force distribution unit that comprises at least one medium or material that is unable to withstand a static shear stress and deforms continuously under the action of a shear force. In a preferred embodiment, this medium or material is a gas, a shear force. | 06-18-2009 |
| 20100087003 | DEVICE AND METHOD FOR THE MECHANICAL DECOLLATION OF CELLS FROM A CELL COMPOSITE - A device for mechanically decollating cells from a cell composite, particularly a shear rotor, a cell isolation unit including such a shear rotor and a method for decollating cells from a cell composite. The aforementioned device includes a rotor having a rotor wall, which is concentrically arranged in a receptacle. A rotor seat is connected to a motor and to which the rotor can be fixed in a detachable manner. A rotational movement of the motor can be transmitted to the rotor by means of the rotor seat. The rotor tapers longitudinally towards the bottom of the receptacle so that different circumferential speeds of the rotor can be transmitted to a liquid sample in the receptacle via the rotor wall. | 04-08-2010 |
| 20100143197 | Container Holder - A container holder for a multiplicity of tubular sample containers with a frame made of a rigid plastic material, comprising a panel with a multiplicity of holes, and a coating of the frame which is made of an elastic plastic material or of rubber, and which partially closes off the cross section of the holes. | 06-10-2010 |
