Abstract

The invention provides a cutting balloon which comprises a balloon body and a cutting wire, wherein the cutting wire is arranged in the radial direction of the outer surface of the balloon body, the two ends of the cutting wire are respectively fixed on the two ends of the balloon body, and the cutting wire comprises a foldable structure. Compared with the prior art, the cutting balloon has betterpassing ability as the flexible cutting wire is arranged on the surface of the cutting balloon; furthermore, the cutting balloon can cut plaque tissues in expansion and has small damage to inner membranes; meanwhile, the cutting wire is fixed to the surface of the cutting balloon or can slide in the telescopic direction, so that the problem of displacement or winding in a cutting process is avoided; furthermore, the foldable structure not only can provide axial length compensation for the cutting wire in expansion of the balloon, but also can improve friction between the balloon body and blood vessel walls; thus, the balloon is prevented from displacement.

Description

technical field

[0001] The invention belongs to the technical field of balloons, in particular to a cutting balloon and a balloon catheter. Background technique

[0002] Percutaneous coronary intervention (PCI) is an important means of revascularization treatment for coronary heart disease. The number of patients with coronary heart disease undergoing PCI in my country is also increasing year by year. The technical update of interventional devices and the improvement of surgical skills have made more patients with coronary heart disease Patients benefit from it. The instruments that need to be used in PCI include guide catheter, guide wire, balloon and stent, etc. The guide wire is the track for the instruments to pass through the coronary artery lesion during PCI, and it is one of the important factors that determine the success of PCI. The balloon is the main tool for dilating coronary lesions, relieving vascular stenosis and ensuring the smooth placement of stents. [00...
