Title: BALLOON CATHETER SYSTEM FOR SEALING PUNCTURE POINTS IN BODY CAVITIES, HOLLOW ORGANS OR IN PERCUTANEOUS SYSTEMS IN MAMMALS
Abstract:
The present invention relates to a balloon catheter system for sealing puncture points or openings in body cavities, hollow organs or in percutaneous drainage operations in mammals, consisting of a filling catheter (14) for a filling medium with a shaft, on the distal end of which a first balloon (20) which can be filled with the filling medium is arranged with a further balloon (22) which can be filled with the filling medium arranged proximally spaced apart therefrom, which balloons close the puncture point or the opening on the two sides in the filled state of the balloon (20, 22), and a hollow needle (12), which is open at the shaft or the shaft end and can be guided in the lumen of the filling catheter (14), for filling the two balloons (20, 22) with the filling medium, wherein the shells of the two balloons (20, 22) enclose the shaft of the filling catheter (14) and the filling catheter (14) in each case has an opening (23.1, 23.2) arranged in the balloon lumen to fill the two balloons (20, 22), whereby, when the hollow needle (12) is drawn back, the distal balloon (20) is firstly filled with the filling medium followed by the balloon (22) proximally spaced apart therefrom.
