Abstract: A surgical targeting system of an intramedullary nail, which includes an extracorporeally arranged external transmitting unit. Further included is a plurality of first transponder units coupled with and arrayed along the length of the intramedullary nail, each adapted to be actuated by the external transmitting unit. Additionally, a plurality of holes are disposed within and arrayed along the length of the intramedullary nail. Each of the plurality of holes are situated between each of the plurality of first transponder units. Further, a first transmission section is between the external transmitting unit and each of the plurality of first transponder units via which the plurality of first transponder units are actuated. Additionally included is a second transmission section through the intramedullary nail between the plurality of first transponder units and a second transponder unit.

Abstract: A data transmission system connected to a bone implant has an extra-corporeally arranged external transmitting unit an implantable internal first receiving unit adapted to be actuated by the external transmitting unit. An internal transmitting unit is adapted to be coupled and implanted to the implant. A second transmission section is located between the external transmitting unit and the internal first receiving unit, via which the internal transmitting unit is actuated. A second receiving unit and a first transmission section is located between the internal transmitting unit and the second receiving unit. The first transmission section operates with acoustic vibrations or waves.

Abstract: The invention relates to adhesives for medical applications and methods of their preparation and use.

Abstract: The invention relates to a kit comprising the following individual components: (a) polymers comprising at least one free amino group, (b) bridge molecules selected from the group consisting of monocyclic ortho-dihydroxyaromates, mono-cyclic para-dihydroxyaromates, bicyclic monohydrxyaromates, polycyclic monohydroxyaromates, bicyclic dihydroxyaromates, polycyclic dihydroxyaromates, bicyclic trihydroxyaromates, polycyclic trihydroxyaromates, and mixtures thereof, and (c) polyphenoloxidases, in particular, lignolytic polyphenoloxidases, whereby the individual components b) and c) are not in contact.

Abstract: A method for the antimicrobial provision of implant surfaces with silver, in which the method comprises an anodizing of the implant surface with an electrolyte, in which the electrolyte has a silver-yielding substance. Alternatively, the method comprises a silver implantation or a silver PVD deposition.

Abstract: An interlocking nail, particularly for fractures of the proximal femur having a proximal portion that has provided therein a bore preferably extending obliquely to the axis of the proximal portion for receiving a screw or pin, particularly a femoral neck pin. The bore is formed so that the lateral edge portions located on opposed sides are flattened and rounded at the inlet end or also the outlet end of the bore.

The bore is formed so that the lateral edge portions located on opposed sides are flattened and rounded at the inlet end or also the outlet end of the bore and continuously pass over into adjacent edge portions towards the proximal and distal sides of the inlet end and/or outlet end.

Abstract: A process and apparatus for use in mixing and applying a flowable substance that consists of a powdered first component and a liquid second component. The mixing of the two components form a flowable substance, especially a bone cement. The apparatus uses an injection syringe. The first component is placed into the injection syringe after removing the syringe plunger and placing a closing device or cap onto the dispensing end of the syringe. The liquid component is added to the syringe, preferably from a second syringe filled with the liquid component via a hollow needle of the second syringe. The first syringe is closed at the filling with the syringe plunger under the load of sufficient air in the syringe cylinder. The components are mixed by shaking the first syringe. The lid of the first syringe is removed and a hollow needle is placed onto the first syringe and the flowable substance is delivered at a desired site.

Abstract: A static trauma or fracture fixation device is made from a metal such as steel, cobalt-chrome alloy or titanium alloy. When in use, the implant has at least one portion which is either in contact with bone tissue or with metal. Although such a metal may be considered a static implant, it undergoes dynamic loads which cause micro-motion. In order to reduce wear, corrosion and modify the frictional characteristics of the surface, coatings may be applied. The coating may be a diamond-like carbon coating of the metal, carbon and hydrogen type. This coating may be applied by physical vapor deposition and/or chemical vapor deposition. Other coating processes may include nitrogen or oxygen diffusion processes or carbon diffusion processes. Anodization may also be used as a coating to modify the wear and corrosion resistance of the base metal.

Abstract: An antibacterial device has a surface with a layer that releases ions with an antibacterial effect, e.g. silver ions. The effect of silver is strongly antiseptic even in the bound state, since silver ions contained in the oxide layer of the metal surface exert a blocking effect on the thiol enzymes in the microorganisms. By using a layer that releases silver ions, the risk of bacterial infections can be clearly reduced. Other ions with an antibacterial effect, e.g. copper, can be used by themselves or together with the silver ions. The device may also have a layer having a matrix that is preferably made of plastic. The matrix serves to continuously release silver ions or other ions with an antibacterial effect. With a continuous release of metal ions, a long-lasting antibacterial effect in the tissue is achieved by the surface.
