Embodiments of the present disclosure are directed to a systems, devices and methods for displacing bones of a living mammal. In some embodiments, a device is provided which includes at least two engagement elements positioned at a distance from each other for engagement with two separate bones Each of the engagement elements may be carried by a support part which in turn is supported in a support portion of a distance unit (). The said support part and support portion form a support unit, where each engagement element extends at an angle (&#x3b1;) with respect to a straight line (L) between two support units. At least one of the support units includes an arrangement for altering the angle which includes an actuating unit maneuverable for adjustment of the angle (&#x3b1;). Some embodiments of the disclosure are directed to a system for engagement with vertebrae including such devices (noted above), as well as uses of the device and associated methods of treatment.

Displacement device, use and system therefore

A system and a method for making an injectable mixture using at least one first pulverulent component and a second liquid component with a first piston/cylinder arrangement with a cylinder with an axial extension and a piston, wherein the cylinder includes a measured amount of the pulverulent component, a separate reservoir including a corresponding measured amount of the liquid component, and a transfer device for sealed transfer of said amount of the liquid component to the cylinder for subsequent mixing and injection of the completed mixture. The first piston/cylinder arrangement is an injection syringe. A mixing element being manoeuvrable by a user is positioned inside the cylinder. At least one gas transferring channel means leading to the cylinder is arranged at the cylinder. Engagement means are arranged for connecting the first injection syringe to the separate reservoir during transfer of the liquid component.

Mixing system and mixing method for medical purposes

A positioning device for placing a prosthesis device in a spinal column of a living mammal, the device including at least one holding means for cooperation with the prosthesis device and for guiding thereof during positioning. The positioning device may also include fixing means for fixation with respect to at least one vertebra, where the fixing means includes locking means, which in a first, free state, allows adjustable movement of the holding device and thereby of the prosthesis device, and in a second, locked state, fixes the holding means and thereby the prosthesis device in a selected position. Embodiments of the disclosure also include Embodiments of the invention also include a system.

Positioning device for a prosthesis device and system therefore

Surface coating method for deposition of a chemically bonded ceramic coating on a substrate, includes the steps of preparing a curable coating slurry, depositing a coating of the slurry on at least a section of the substrate surface, and hardening the slurry. The step of preparing a curable coating slurry includes mixing calcium aluminate powder with water and at least one water-reducing-agent, such that a water-to-cement ratio in the range of 0.1 to 0.9 is achieved.

Coating method and coated devices

Objects of titanium or titanium alloys having the surface converted to a hard and wear-resistant nitride layer with good adhesion, which is distributed uniformly and also provides internal capillaries. The objects are produced by being treated in a vacuum furnace with an atmosphere of pure nitrogen gas at a temperature of 650.degree.-1000.degree. C. and at a pressure below atmospheric pressure. The thickness of the nitride layer can be controlled by controlling the treatment time and temperature.
