Abstract

The invention discloses an indented balloon for vascular calcification plaques, which comprises a balloon body used for expanding a vascular wall; a indentation structure which is mounted on the outer surface of the balloon body, wherein the indentation structure comprises at least one indentation filament body, and the at least one indentation filament body is spirally arranged on the balloon body in a sleeving mode in the axial direction of the balloon body; in the radial direction of the balloon body, the free end of at least one indented filament body is spine-shaped; and in an expansion state, the free end of the indentation filament body is in contact with the calcified plaque. When the balloon body is conveyed to a calcified plaque lesion position, the spiral indented filament bodies can form a sliding effect, and the balloon body is promoted to smoothly pass through the calcified lesion position. The indented filaments on the outer surface of the balloon body are spiral, so that overhigh tension cannot be locally formed, the risk of complications such as vascular interlayer and vascular perforation is reduced, and the safety is improved. In addition, the free ends of the indentation filament bodies can generate impact force on the calcified plaque, so that the calcified plaque forms cracks and is separated from the blood vessel wall, and therefore, the treatment effect of the calcified plaque is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a scored balloon for vascular calcified plaque. Background technique [0002] Atherosclerosis (AS) is the main cause of coronary heart disease, cerebral infarction and peripheral vascular disease. The prominent sign of atherosclerosis is coronary artery calcified plaque, which can increase the stiffness of the blood vessel wall, reduce the compliance of the blood vessel wall, and make the atheromatous plaque unstable. [0003] Percutaneous coronary intervention (PCI) and stenting are the main methods for treating coronary calcified plaque. Percutaneous coronary intervention can dredge the coronary lumen, and stent surgery can assist percutaneous coronary intervention to expand the vessel wall to prevent acute coronary occlusion. [0004] Percutaneous coronary intervention combined with rotational atherectomy (coronary trartsluminalrotational atherectomy, Rotablator) can...
