An apparatus for providing a liquid component as a first starting component of a bone cement dough from two starting components, comprising a receptacle in which a tank containing the liquid component can be stored, an opening means for opening the tank, a reservoir, fluidically connected to the receptacle, for receiving the liquid component from the tank, at least one port for fluidically connecting the apparatus to a syringe in which a powder component can be stored as a second starting component of the bone cement dough, and at least one conducting means which fluidically connects the reservoir and the at least one port to one another.

A method for coating implants with a polymer layer containing at least one pharmaceutical active ingredient. A kit-of-parts suitable for carrying out the method, and to a corresponding device obtained from the kit-of-parts.

An antimicrobial agent for use in the treatment or prevention of a bacterial infection, wherein a patient is selected for treatment using the antimicrobial agent based on the level of D-lactate in a patient sample.

One aspect relates to a device for producing a spacer having a stem mold which has an inner space, wherein the inner space is accessible via a proximal opening and wherein the stem mold has a proximal wall which peripherally delimits the proximal opening of the stem mold, a head mold which has in the interior thereof a hollow space, wherein the hollow space has a spherical surface-shaped inner surface and is accessible via a distal opening, wherein the head mold has a distal wall which peripherally delimits the distal opening of the head mold, a metal core which has a stem part, a head part and a flange, wherein the flange projects out from the metal core, is arranged between the stem part and the head part and has a proximal surface and a distal surface, wherein the stem mold and the stem part are shaped such that the stem part is arranged in the inner space, when the proximal wall is resting against the distal surface, and wherein the head mold and the head part are shaped such that the head part is arranged in the hollow space, when the distal wall is resting against the proximal surface.

Augmentation material having a wire and, in axial alignment along the wire, a plurality of groups of axially adjacent connecting elements that extend radially from the wire, wherein the connecting elements are designed such that, when a first group from the plurality of groups is pressed together with a further group from the plurality of groups, the connecting element of the two groups can be connected to one another in a positive-locking and/or friction-locking manner.

A device and method for applying a pharmaceutical fluid comprising a hollow cylindrical body, which surrounds a channel that extends through the body from a proximal body end to a distal body end of the body, wherein an outer surface of the body has at least partially an external thread, and has a connecting element arranged at the proximal body end, via which a proximal channel end of the channel can be reversibly connected in terms of fluid conduction to a reservoir for the pharmaceutical fluid.

A device for determining the required distance between a head region and a shaft region of a joint spacer, to a system, to a method for producing a joint spacer, and to a use. A device for determining the required distance between a head region and a shaft region of a joint spacer includes a head and a shaft, which can be positioned at different distances from one another, wherein the device further includes a fixing apparatus for fixing a distance between the head and the shaft. The device allows the required shape of a hip joint spacer to be determined intraoperatively by adjusting the distance of the head from the shaft to the specific anatomy of the patient.

One aspect is a method for producing a bone cement from monomer liquid and cement powder using a depressurization device. The method is performed using a device comprising a cartridge having a drive piston, and a central piston being permeable to gases and the monomer liquid and impermeable to the cement powder and being arranged between the drive piston and a cartridge head. The method comprising the steps of expelling residual gases into the surroundings of the device by means of the movement of the drive piston; displacing gases between the powder particles with the inflowing monomer liquid; and depressurizing a cavity of the cartridge, by partially removing the contained monomer liquid. The invention also relates to such a device for mixing a bone cement, with a depressurization device.

An apparatus for pressing out bone cement from a cartridge, to a use of the apparatus, and to a system for pressing out bone cement. An apparatus for pressing out bone cement from a cartridge comprises a threaded rod with an external thread, a handle for rotating the threaded rod, and an adapter unit for mechanically connecting to a cartridge for bone cement. The adapter unit has a passage with an internal thread for the threaded rod. An outer surface of a thread turn of the external thread is not more than 370 mm 2 .

An implantable spacer for delivering a medical fluid to a patient, wherein the spacer comprises a first sub-element, a second sub-element, an outer surface, a channel, a plurality of delivery valves, and a joint element with a joint body, wherein the joint element movably connects the first sub-element to the second sub-element.
