Abstract: A method is proposed for producing a CMC-component (6) comprising at least the steps of pyrolizing (2) a green body (1; 10) made of a fiber (15)-reinforced thermoplastic material (14) and infiltrating (4) the pyrolized green body by a liquid carbide forming substance (31). The fibers (15) of the green body (1; 10) are arranged in one or several strands (16), each of these strands (16) having a main extension direction. The lengths of the fibers (15) of each strand (16) are larger than the overall length (L) of the green body (1; 10) along the main extension direction of this strand (16).

Abstract: The inter-vertebral implant comprises a first part (2, 21, 26) and a second part (3, 22, 27), which may be uniportally implanted in a disc cavity (B) and connected to each other therein. The parts (2, 3; 21, 22; 26, 27) comprise an opening (4, 5; 28, 29) for housing spongiosa or bone replacement material. Both parts (2, 3; 21, 22; 26, 27) have connector means (8, 9; 23, 24; 31, 35), which engage with each other on implantation in the disc cavity (B) and thus connect both parts (2, 3; 21, 22; 26, 27) to each other. At least one part (3, 22) preferably comprises a groove (8, 23) in which a spring (9, 24) of the other part may be introduced in a sliding manner. The groove (8, 23) and the spring (9, 24) are arranged on the inner narrow faces (10, 11) of both parts (2, 3; 21, 22) which are to come together. The implant may be implanted uniportally through a transforaminal or an extraforaminal opening (T, E) equally carefully.

Abstract: A composite of polymer or ceramic material has reinforcing fibers. The composite is for use in manufacturing medical implants like osteosynthesis plates, endoprostheses, screw coupling elements, surgical instruments, and similar components. The fibers and fibrous parts are made from a material that absorbs X-rays so that it can be seen during X-ray examination.

Abstract: A fastening element (1) to be inserted into an opening, or bore (2) of a work piece (3) is provided having a shaft (5) that is insertable into the bore (2) and has a roughened and/or profiled surface (4), and optionally includes a stop collar (6). The fastening element (1) is preferably formed from a fiber reinforced, elastically deformable material, and its shaft (5) can be or is inserted into the bore (2) in a force-fitting manner under an elastic deformation.

Abstract: A device for precisely placing instruments or implants in body organs with the aid of a targeting device (40) interacting with a computer tomograph, characterized in that the targeting device is arranged in the form of a navigation device (30) on a carrier (2) which is diplaceable on a substructure like a carriage which can be fixed in relation to the substructure and in that the navigation unit (30) comprises a retaining element for holding and guiding a targeting instrument, implant or other object. The navigation unit (30) can be displaced and/or rotated on one or several planes in relation to the carrier and the retaining element can be displaced and/or rotated on one or several planes in relation to the navigation unit (30), being reciprocally fixable in the adjusted position thereof.

Abstract: An implant used in stabilising operations on the thoracic and lumbar vertebral column for restoring the load-bearing capacity of the vertebral column is provided. An insertion region of the implant (I) comprises a wedge-shaped distraction part (C), which permits the vertebral bodies to be pushed apart in order to increase the intervertebral distance. In addition, guide elements in the form of grooves (7) and/or strips are provided on said wedge-shaped distraction part (C) and/or in the implant part (D).

Abstract: The invention concerns an implant in the form of a compression resistant hollow body (1), used in procedures for stiffening the vertebral column (2). The hollow body (1) includes two open receptacles (3, 4) mutually oriented toward one another that interlock and form the implant proper (cage). The two receptacles (3, 4) can be separated by pressure through insertion of a filling material, thereby producing an expansion of the hollow body (1) after it has been implanted.

Abstract: An osteosynthesis screw (1) used especially for application by a translaminar vertebral screw, comprises a shaft (3) at least partially provided with a thread (2) and a head (4) formed at one of its ends and having a notch (5) for a tool. Said shaft (3) has a section (A) with a thread (2) on the end section oriented towards the head (4). The remaining section (B) of the shaft (3) up to the free end is produced without a thread. The head (4) has a diameter (D1) corresponding at least approximately to the outer diameter (DA) of the thread (2) and is provided with the inner notch (5) for a tool. The section (A) of the shaft (3) with the thread (2) has a configuration of uniform thickness, e.g. a trilobular configuration. Thus, the invention provides an osteosynthesis screw (1) exhibiting a short section (A) with a thread (2) and a long section (B) without a thread, said screw having a pull-out head (4) which is secured both axially and rotationally.

Abstract: An implant for osteosyntheses including a plate with a plurality of holes following in succession in the longitudinal direction whereby at least most of the holes intended to receive the screws are offset in alternation generally away from a center plane whereby a center axis of each of the holes forms an acute angle with the center plane of the plate.

Abstract: The invention relates to an osteosynthesis screw (1) comprising a shaft (3) with a thread (2) and a head (4) formed at one end and having a notch (5) for a tool. The shaft region (3) with the thread has a configuration with a uniform thickness, ie. trilobular.
