Problems solved by technology

However, for some vascular stenotic lesions with diffuse lesions and severe calcification, conventional balloon dilatation may easily cause large plaques to fall off, and as the blood flows to the smallest end of the blood vessels, embolism occurs, which leads to more severe lesions. serious complications
Regardless of whether it is conventional balloon dilation or cutting balloon dilation, there are such risks

Abstract

The invention discloses a balloon expansion catheter with a thrombus filter, which comprises a thrombus filtering device, a connecting tube, a balloon, an intermediate catheter, a stress tube and a catheter seat in sequence from the distal end to the proximal end. When in use, as the liquid medium fills the balloon, the thrombus filter is squeezed out of the restricting tube at the same time, so that the thrombus filter is released. to capture. After the expansion is completed, the catheter is seated to draw negative pressure to make the balloon return, and the negative pressure makes the thrombus filter retract into the restricting tube to achieve the purpose of recovery. The invention can effectively reduce the risk of plaque shedding when the balloon is expanded.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a balloon dilation catheter with a thrombus filter for treating intravascular calcification lesions. Background technique [0002] Vascular calcification is one of the most serious stages in the development of cardiovascular disease. The cause of intravascular calcification is the deposition of calcium salts on the inner wall of the blood vessel, resulting in the loss of the intima of the blood vessel and the growth of plaques, resulting in vascular stenosis. 80% of vascular injuries and 90% of patients with arterial diseases are accompanied by vascular calcification. The morbidity and mortality of cardiovascular diseases increase by 3-4 times. [0003] At present, the treatment of vascular calcification uses balloon catheter intervention as the main measure, which not only has less trauma, less pain, but also has good curative effect. However, for some vascular stenoti...
