Abstract
A coupling assembly for connecting a flexible catheter to the hub cone of a sheath for inserting the catheter into a punctured body cavity consists of a housing having two separable housing halves which jointly form a passage for the catheter and have their patient-proximal front end provided with a tip for insertion into the hub cone of the sheath. In the passage, there is arranged shaped sealing formed as a hollow cylinder of an elastic material, provided as a tube tightly surrounding the catheter and having a thickened head portion. The outer diameter of the head portion is adapted to the outer diameter of the tip of the housing, and the tube is inserted into a widened portion of the passage such that the head portion of the tube abuts against the front face of the tip. Such a shaped sealing acts as a closing stopper which prevents that blood can travel rearward between the separating slits of the housing halves and escape to the outside.
