Abstract: A method, system and devices for the reconstruction of ribbon shaped ligaments following the anatomical native insertion sites of the ligaments in the corresponding bones is described. The reconstruction of the anterior cruciate ligament of the human knee is depicted. The system includes means for positioning and creating bone-tunnels, the preparation of grafts and the fixation thereof. The devices intended for bone tunnel creation take into account the ribbon-shaped nature of the ligament and can be adjusted to patient specific anatomy and take into consideration the various typologies of the ligament insertion sites. The method and devices for graft preparation are construed to reflect the anatomy of ligaments under consideration as close as possible to native ligaments by imitating the ribbon-like nature of native ligaments. The presented fixation methods follow this principle and are intended to support the ribbon-like nature of the grafts and are intended to support in-growth of the grafts.

Abstract: A three-dimensionally contoured, acoustically effective heat shield for a motor vehicle, includes a heat reflection layer made of a metallic material, such as aluminum, and an acoustic insulation layer made of a thermoformable, rubber-elastic and thermoplastic material, and a hot-melt adhesive film made of a polymer material. The adhesive film is disposed between the heat reflection layer and the insulation layer and forms a plane mechanical connection between the heat reflection layer and the insulation layer. A method for producing the three-dimensionally contoured, acoustically effective heat shield includes the steps of providing a two-dimensionally extending material composite and thermoforming the composite in a thermoforming tool, in which at least one mold half has a molding tool temperature that is above the activation temperature of the heat-activatable adhesive film and above the melting temperature of the rubber-elastic material of the insulation layer.

Abstract: A medical cutting instrument for cutting muscles and tendons, with an instrument body that includes a handle on its proximal end and at least one cutting knife in the area of its distal end. To provide a medical cutting instrument that guarantees ease of handling and simple structure along with secure cutting of the muscle/tendon tissue, the instrument body should be of grooved configuration in the area of its cutting knife in such a way that the instrument body includes a hollow space extending in the longitudinal direction of the instrument body to receive and guide the muscle/tendon tissue that is to be cut, such that the instrument body includes an opening extending in the longitudinal direction of the instrument body and the cutting knife constitutes a side of the instrument body.
