Device for a device for use in healing processes, comprising a balloon body with two balloon segments of different diameters, and method for producing such a device

摘要

The invention describes a catheter balloon for the sealing retention of a device for the supply or discharge of a substance into the body of a patient or for the occlusion or space-filling tamponade of a natural or artificial body opening, the balloon body consisting of separately shaped segments of different wall thickness and / or material hardness and / or polymer types, and the individual segments are each adapted in terms of material thickness, material hardness, or material type to the mechanical function to be performed in each case, i.e., for example, a relatively larger, retaining diameter portion of balloon made of relatively thick-walled, moderately stretchable for which Anchoring of the device advantageous material, and a diameter of the sealing balloon portion relatively smaller, made of relatively thin-walled, volume-expandable material adapted for the tissue-protecting seal, and the respective one, sparks Ionically optimized segments are preferably connected to form a fillable balloon compartment by preferably circularly overlapping circular contact surfaces, for example by means of an adhesive or solvent attached in the intermediate gap.
