Abstract: According to the invention a working cannula (1) is fixedly joined to a medical coupling element (3) which is placed onto a sealing cannula (2) and can be screwed onto same. The medical coupling element (3) has an actuating lever (34) and a covering plate (39). When the medical coupling element (3) is rotated by means of the actuating lever (34) in relation to the sealing cannula (2), the working cannula (1) is partially pulled into the sealing cannula (2) to such a depth that inlet openings (11) in the proximal end of the working cannula (1) are drawn into a sealing chamber (14) at the proximal end of the sealing cannula (2). This ensures that the outlet openings (6) through which, for example, fibrin adhesive can be administered into the puncture channel, do not enter an artery. In the insertion position the covering plate (39) simultaneously covers the sealing tube (5) through which the sealing material is injected.

Abstract: An osteosynthetic implant for a mechanical connection of fractured elements, made of a polymeric biodegradable base material, for use in reconstructive osteosynthesis. An active ingredient assists the regeneration of bone tissue in a fracture area and acts together with the implant to assist growth in the fracture area, so that the mechanical load-bearing capability of the healing fracture increases faster or at least as fast as the load-bearing capability biodegradable implant decreases when decomposing.

Abstract: A device for introducing a two-component fibrin sealant into a puncture channel in the vicinity of an arterial or venous puncture point, said device comprising a working cannula extending axially from an upper end to a lower end through a sealing cannula, said working cannula being used for intravascular introduction of instruments into a vessel. The working cannula is surrounded by the sealing cannula at a distance from the working cannula whereby the fibrin sealant passes from a connector at said upper end of said sealing cannula to at least one slitshaped radially directed outlet opening in said sealing cannula between said sealing cannula and said working cannula.
