Balloon catheter device for atraumatic expansion of hollow organs, and a method for producing such a balloon catheter device

Abstract

According to the invention, a balloon catheter device for the atraumatic treatment of hollow organs is provided. It comprises a balloon catheter with a balloon, a tubular functional sleeve applied to the balloon for the directed segmented cushion-like unfolding of the balloon for the dilation of a hollow organ and simultaneous application of active substance into the hollow organ wall, and wherein the functional sleeve is folded in an initial state together with the balloon about a sleeve longitudinal axis, and wherein the folding of the functional sleeve is directed as pleating about a sleeve longitudinal axis and in a final state is unfoldable for abutting against an inner wall of a hollow organ, and wherein the tubular functional sleeve has planar sections and/or planar struts which delimit through-openings, so that the functional sleeve is used for sectional limitation of a balloon dilation of the balloon.
