Abstract

The invention discloses a calcified plaque cutting balloon. The balloon comprises a balloon body, cutting wires and elastic telescopic components, wherein the cutting wires are fixed to the elastic telescopic components at the two ends of the balloon body and distributed on the outer surface of the balloon body in parallel in the axial direction. The balloon catheter has the advantages that the cutting wires are distributed on the outer side of the balloon body in parallel in the axial direction, can regularly cut diseased regions under low pressure and meanwhile have the good capability of penetrating through complex lesions, the balloon catheter connecting structure is a special-shaped multi-cavity elastic tube with the good elasticity, axial elastic telescopic movement of a cutting component is facilitated, and the banana effect is prevented; meanwhile, due to the shape design of the cutting wire, the contact area between the cutting wire and a diseased region is greatly reduced, the sliding risk of the balloon in the expanding process is reduced, and the cutting and expanding capacity of the balloon on fibrotic lesions and plaques is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a calcified plaque cutting balloon used for expansion and treatment of coronary fibrous calcification lesions and in-stent restenosis (ISR) in PCI operations. 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. 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. [0003] The cutting balloons currently used include: blade cutting balloons, single wire cutting balloons, and multiple wire cutting balloons. [0004] Before the expansion of the blade cutting balloon,...
