Abstract

This invention discloses an external guidewire shockwave balloon catheter including a balloon, a catheter, and a guidewire. The catheter includes an inner support rod and an outer tube that are deformable for supporting the balloon. The inner support rod is located inside the outer tube and is coaxial, with a gap between the outer tube and the inner support rod. The inner cavity of the balloon is communicated with the gap to allow the introduction of electrolyte fluid. The distal end of the inner support rod extends out from the distal end of the outer tube, and the proximal end of the balloon is sealed to the distal end of the outer tube. The distal end of the balloon has a balloon tip, which is sealed to the distal end of the inner support rod. A corona generator is located at the position of the inner support rod where it is positioned within the balloon, and an inlet communicating with the guidewire hole is located at the balloon tip. Compared with conventional technologies, by placing the external guidewire at the balloon tip, this invention achieves greater stress concentration on the vascular wall while guiding the balloon into the blood vessel and reaching the lesion site, and also enables the guidewire to function as a cutting guidewire.
