  • Patent number: 10299949
    Abstract: A release device for releasing a medical implant from an insertion device, in which the implant can be released by a relative movement between a first and a second insertion element, wherein the insertion device has a proximal end, which faces the user during use, and a distal end, which is distanced from the user during use. Between the proximal and the distal end, a shortening region is provided, in which, when generating a targeted relative movement between the first and the second insertion element of the insertion device, a length of at least one of the insertion elements between the proximal end and the distal end can be shortened.

  • Publication number: 20190133741
    Abstract: Packaging has an outer sleeve, which surrounds an interior space for receiving an object, such as a sterilized medical implant. A separate container is arranged in the interior space and surrounds an absorber in a gas-tight manner, such that a gas present in the interior space cannot pass to the absorber. The container is configured to be opened by the application of force when the outer sleeve is closed, such that a gas disposed in the interior space can pass to the absorber and can be absorbed thereby. In preferred embodiments, the absorber absorbs air with the reactive constituents O2 and/or H2O. Depending on the application, however, other gases can also be absorbed by the absorber. A method for packaging is also provided.

  • Patent number: 10172732
    Abstract: A prosthesis delivery handle with a bushing (66) with two adjacent internal threads (64, 74) with different diameters and pitch surrounding a tubular threaded first shaft member (36) cooperating with the first thread (64) and a second inner member with a protrusion (82) extending through an axial slot in the tubular first member such that the protrusion runs in the second thread (74). First and second members are connected to an external shaft (112) and an internal element (102) so that when the bushing is rotated first and second members travel axially with different speeds the internal shaft and an external shaft move accordingly.

  • Patent number: 9962210
    Abstract: A bone screw formed primarily of a magnesium alloy has a self-tapping thread, and is prestressed with a retained torsional stress oriented oppositely to the direction in which the screw is screwed into bone. The pre-stressing opposes the torsional stresses arising from screwing in the screw, thereby raising the effective strength of the screw and/or allowing for a reduction in its size/mass.
