  • Patent number: 4751924
    Abstract: The invention relates to a balloon catheter, particularly an endotracheal theter, with a catheter tube of elastic, tissue-compatible material, in which the signal balloon (6) near the proximal end (3) of catheter tube (1) and the retention sleeve (4) near the distal end (2) of catheter tube (1) are present in a foil hose (15), extending over the entire length of the catheter tube, sheathing the catheter, and they are preformed in the hose in one piece. Foil hose (15) engages loosely on the catheter tube at the points of signal balloon (6) and retention sleeve (4), and is otherwise connected tightly with the catheter tube. Feed tube (5) connecting retention sleeve (4) with signal balloon (6) and the proximal end of the catheter tube can be formed by one or more grooves (14) in the outside wall of respirator tube (1), and the foil hose (15) covers the grooves to seal them gas- and liquid-tight from the outside.
