Thrombus aspiration catheter

Abstract

The invention provides a thrombus aspiration catheter. The thrombus aspiration catheter comprises a catheter seat, a stress release tube, a catheter body and a developing identifier; when thrombus aspiration is carried out, blood vessels can be blocked, so that broken small thrombus is prevented from flowing to smaller blood vessels at the far end; more importantly, in the aspiration process, thrombus can be crushed and cut through thrombus crushing equipment at the tail end of the catheter; old or hard thrombus can be smoothly sucked out through suction, so that the success rate of an operation is greatly improved, and the risk of the operation is reduced; the invention has great significance in reducing complications and improving the aspiration effect of thrombus.

Description

technical field

[0001] The invention belongs to the technical field of medical devices, in particular to a thrombus suction catheter for cardiovascular intervention. Background technique

[0002] A thrombus is a small piece of blood that forms on the surface of a peeled or repaired vessel in the cardiovascular system. In variable fluid dependence, thrombi consist of insoluble fibrin, deposited platelets, accumulated leukocytes, and trapped erythrocytes. If the thrombus forms a blockage in the blood vessels of the human body and interrupts the blood flow, it is easy to cause myocardial infarction, stroke and other life-threatening diseases.

[0003] Currently, thrombolytic therapy is still the mainstream treatment for ischemic stroke, but it has certain limitations, mainly reflected in the short treatment time window and low rate of revascularization. The treatment method of mechanical thrombectomy has significant advantages in the treatment effect. At present, the commonly...
