ABSTRACT:
The invention relates to a method for the production of a medical instrument, in particular a tube or catheter, with a balloon made of an elastomeric and/or thermoplastic material, comprising the steps of providing an inflation line for the balloon on or in one hose section and applying thereafter the cuff-shaped balloon with its two ends closely fitting and overlapping one outlet of the said inflation line. To render the production economical, a coat (3) of a parting compound is applied to the hose section (1) in the area where the balloon (10) is to be formed, whereafter the hose is sheathed by extrusion with a sheathing coat (5) of a thermoplastic or elastomeric material.
