An intracranial balloon dilation catheter

Abstract

The application provides an intracranial balloon dilatation catheter, which comprises a tip head sleeve arranged outside a tip tube, the tip tube is welded and connected with a distal end of an inner tube and communicates with the inner tube; a balloon and an outer tube are sequentially arranged outside the inner tube from the distal end to the proximal end of the inner tube, the balloon and the outer tube communicate with each other, and a plurality of developing marks are arranged on the outer surface of the inner tube in the balloon; a quick exchange port is arranged near the proximal end of the inner tube; the proximal end of the outer tube is welded and connected with a push tube, a plurality of length mark rings with different ring widths are arranged on the push tube; a stress dispersion tube is welded and connected between the push tube and a catheter seat, and the catheter seat is used for inputting a filling medium to inflate the balloon. After the technical scheme is adopted, the narrowed blood vessel can be dilated by the balloon, the action part of the balloon and the catheter insertion length can be conveniently identified, the balloon or the balloon inner membrane composed of piezoelectric material is arranged, the blood vessel or nerve is provided with electric stimulation, and the treatment effect is further improved.
