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.

In 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 sealing cannula (2), through which a working cannula, having an open distal end and a proximal end with a fixedly connected medical coupling, extends axially from an upper end through a lower end of said sealing cannula (2), said working cannula movable within said sealing cannula (2) and suitable for conveying intravascular instruments through said working cannula into a vessel, the improvement comprising: the working cannula (1) surrounded at a distance by the sealing cannula (2), whereby the fibrin sealant is conveyed from a connector (5) connected to said upper end of said sealing cannula (2) to at least one slit-shaped radially directed outlet opening (6) in the sealing cannula (2) between the sealing cannula (2) and the working cannula (1); and said sealing cannula (2) comprising a reinforced cuff (4) formed as one piece on an upper end of said sealing cannula (2), an inner diameter of said sealing cannula (2) being reduced from an area of the termination of the connector (5) to the at least one slit-shaped radially directed outlet opening (6).
