Abstract

The invention relates to a cutting balloon. The cutting balloon comprises a balloon body and a telescopic cutting part, wherein the cutting part wraps the outer surface of the balloon body spirally inthe axial direction of the balloon body. The cutting balloon has the advantages that the cutting part wraps the outer side of the balloon body spirally, thereby improving the cutting effect, dispersing the rigid binding force of the cutting part on the balloon on a same horizontal line, and improving the transversability of balloon cutting; a connecting structure is of a spring spiral structure,thereby making it easier for the cutting part to conduct the axial elastic telescopic movement; a cutting assembly pin is of a hollowed-out structure, thereby improving the radial bending performancewithout weakening the axial supporting performance, and improving the transversability of balloon cutting; the cutting part has an outward protruding structure, thereby improving the cutting performance of the cutting balloon.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a cutting balloon. Background technique [0002] Vascular interventional therapy is an important treatment for revascularization of vascular stenosis. In vascular interventional therapy, balloon catheters are usually used as the main vascular interventional therapy device. [0003] For some stenotic lesions in blood vessels, such as calcification, plaque or fibrosis, ordinary balloon catheters cannot expand the stenotic lesions. To solve this problem, some medical device companies have developed cutting balloons for dilating narrow lesions. [0004] Cutting balloons currently used include: blade cutting balloons, single-wire cutting balloons, and multiple-wire cutting balloons. [0005] The blade cuts the balloon, the blade is adhered to the surface of the balloon, and the narrow lesion is cut open with a sharp blade. However, the penetrability of cutting the ball...
