Spinous process balloon catheter capable of helping to absorb calcified tissues

Abstract

The invention discloses a spinous process balloon catheter capable of helping to absorb calcified tissues. The spinous process balloon catheter is sequentially provided with a needle seat, a tube body, a spinous process balloon body and a spiral tip from the near end to the far end, wherein the needle seat is connected with the near end of the spinous process balloon body through the tube body, the spiral tip is fixedly arranged at the far end of the spinous process balloon body, the tube body comprises an inner tube and an outer tube, and the needle seat is a connecting seat with a luer taper; the spinous process balloon body comprises a balloon, spinous process strips and a reticular permeable membrane, the reticular permeable membrane covers the surface of the balloon, and the reticularpermeable membrane is used for recovering the calcified tissues with broken plaques and reducing the probability of calcification reforming; as a support body of the balloon, the spinous process strips are uniformly distributed and are longitudinally fused with the balloon; and the spiral tip comprises a triangular body and a tip tube, and barium sulfate or bismuth hydroxide is added into the spiral tip, so that the tip developing effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a spinous process balloon catheter which can help absorb calcified tissue. Background technique [0002] Coronary artery calcification is a sign of atherosclerosis, reflecting the degree of coronary atherosclerosis. Increased stiffness and decreased compliance of calcified blood vessels can lead to myocardial ischemia, plaque rupture, and thrombosis, which are important risk factors for cardiovascular events and peripheral vascular diseases. Vascular calcification is a pathological process in which bone-specific hydroxyapatite crystals are actively deposited on the vessel wall due to a high calcium and phosphorus environment and the up-regulation of local or systemic mineralization inducers and down-regulation of inhibitors. During this process, the mineralization defense mechanism of the vessel wall is exhausted, and mesenchymal cells such as smooth muscle c...

Problems solved by technology

However, this technique has little effect on moderate to severe calcified lesions, and the calcified tissue after plaque rupture is prone to form secondary stenosis

[0005] How to provide a spinous process balloon catheter that can recover the calcified tissue of plaque rupture and reduce the probability of calcification re-formation for the treatment of coronary artery calcified lesions, and solve the calcified tissue of plaque rupture caused by the balloon catheter passing through the lesion The technical problems that lead to thrombosis or secondary stenosis have become urgent problems to be solved.
