Abstract: Disclosed is a joining element (10), especially a suture material for surgical use. Said joining element (10) is composed of a first material (12) that is essentially rigid during impingement by a relatively short-lasting tensile load on opposite sides as well as a second material (11) which is connected to the first material. The second material is substantially rigid during impingement by said tensile load on opposite sides while contracting slowly during a second period of time that is longer than the first period of time.

Abstract: Implants (7) for forming a positive connection with human or animal parts include a material, such as thermoplastics and thixotropic materials, that can be liquefied by means of mechanical energy. The implants (7) are brought into contact with the tissue part, are subjected to the action of ultrasonic energy while being pressed against the tissue part. The liquefiable material liquefies and is pressed into openings or surface asperities of the tissue part so that, once solidified, the implant is positively joined thereto. The implantation involves the use of an implantation device that includes a generator (2), an oscillating element, and a resonator (6). The generator (2) causes the oscillating element to mechanically oscillate, and the element transmits the oscillations to the resonator (6). The resonator (6) is used to press the implant (7) against the tissue part to transmit oscillations to the implant (7).

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: An implant suitable for being anchored with the aid of mechanical vibration in an opening provided in bone tissue. The implant is compressible in the direction of a compression axis under local enlargement of a distance between a peripheral implant surface and the compression axis. The implant includes a coupling-in face which serves for coupling a compressing force and the mechanical vibrations into the implant, which coupling-in face is not parallel to the compression axis. The implant also includes a thermoplastic material which, in areas of the local distance enlargement, forms at least a part of the peripheral surface of the implant.

Abstract: A light diffuser (10), which is particularly suitable for introducing diffuse light into a tissue, is produced by interpenetration of a diffuser material in a liquid state into a boundary layer (4) of a porous shaping material, by which process a diffuser surface is formed having a surface structure which represents essentially a negative of the pore structure of the shaping material and comprises undercut structures induced by a surface tension. The light diffuser (10) is, for example, produced by introducing a diffuser blank (1) comprising material which is liquefiable through mechanical vibration into the shaping material and simultaneously stimulating it with mechanical vibrations, such that the liquefiable material liquefies at least there where it is in contact with the shaping material and is pressed into the shaping material.

Abstract: For promoting tissue regeneration on wound surfaces (1) mechanical oscillation is coupled into the wound surfaces. A treatment instrument (2) coupled to an oscillation drive is brought into contact with the wound surface (1), or an implant is impinged with oscillation during and/or after being positioned in the tissue. The oscillation acts mechanically and thermally on the tissue in the region of the treated wound surface (1), and according to the intensity acts in a stimulating, traumatic, necrotic or cell-destroying manner. Therefore, biological elements inhibiting tissue regeneration are destroyed or denatured and the metabolism in the region of the wound surface is stimulated. The effect may also be a mechanical one, slightly compacting or regionally dislocating the tissue.

Abstract: A bone implant (10) is implanted in a cavity parallel to an implant axis (I) and without substantial rotation. The implant includes, on an implant portion to be implanted, cutting edges (14), which do not extend in a common plane with the implant axis and are facing toward the distal end of the implant. The implant also includes surface ranges (16) of a material that is liquefiable by mechanical oscillations. The cutting edges (14) are dimensioned such that they are lodged in the cavity wall after implantation. For implantation, the implant is impinged with mechanical oscillations, resulting in the thermoplastic material being at least partially liquefied and pressed into unevennesses and pores of the cavity wall to form a form-fit and/or material-fit connection between implant (10) and cavity wall, when re-solidified. The cutting edges (14) anchor the implant in the cavity wall.

Abstract: The present invention is concerned with solid, single-dose dosage forms for an increased rate of release of slightly soluble active ingredients. The dosage forms are based on a coherent matrix which disintegrates rapidly in physiological fluids. The matrix comprises one or more slightly soluble active ingredients in the form of fast-release micro- or nanocapsules. The dosage form is particularly suitable for administering those slightly soluble active ingredients for which a rapid onset of action is desired.

Abstract: Am implant (1), in particular a dental implant, comprises surface regions (4) of a first type which have osseo-integrative, inflammation-inhibiting, infection-combating and/or growth-promoting properties, and surface regions (8) of a second type which consist of a material which is liquefiable by mechanical oscillations. The implant is positioned in an opening of e.g. a jawbone and then mechanical oscillations, e.g. ultrasound is applied to it while it is pressed against the jawbone. The liquefiable material is such liquefied at least partly and is pressed into unevennesses and pores of the surrounding bone tissue where after resolidification it forms a positive-fit connection between the implant and the bone tissue.

Abstract: A preparation (10, 11,12,13) to be fixed to a natural tooth part or tooth, in particular for the replacement of a load-bearing tooth part, is for example a filling for a drilled-out tooth (1), a crown, bridge or prosthesis to be placed on a tooth stub, or a tooth pin to be fixed in a tooth root for fastening an artificial tooth, a bridge or a prosthesis. The preparation has surface regions which consist of a material with thermoplastic properties. The preparation (10, 11, 12,13) is designed in a manner such that it has oscillation properties with such low damping losses that for a liquefaction of the material with thermoplastic properties by way of oscillations there are local stress concentrations required, and in a manner such that such stress concentrations only occur in the region of the preparation surface.

Abstract: An implant (1) to be implanted in bone tissue, e.g. a dental implant or an implant for an orthopedic application, comprises surface regions (4) of a first type which have e.g. osseo-integrative, inflammation-inhibiting, infection-combating and/or growth-promoting properties, and surface regions (8) of a second type which consist of a material being liquefiable by mechanical oscillation. The implant is positioned in an opening of e.g. a jawbone and then mechanical oscillations, e.g. ultrasound is applied to it while it is pressed against the bone. The liquefiable material is such liquefied at least partly and is pressed into unevennesses and pores of the surrounding bone tissue where after resolidification it forms a positive-fit connection between the implant and the bone tissue.

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.
