Problems solved by technology

[0004] 2. Mechanical thrombectomy still has the following deficiencies in the process of thrombectomy: 1) There are requirements for the diameter of the blood vessel, and blood vessels with too small inner diameter cannot be reached
2) It may lead to refragmentation of thrombus and blockage of distal blood vessels
3) It may further damage the vascular endothelium, causing secondary damage
[0006] 4. The current local thrombolysis catheters have the following problems: 1) It is difficult to guide super-selective thrombolysis for vessels that cannot be accessed by the guide wire
Current catheters are unable to selectively block the target vessel without blocking the distal blood flow

Embodiment 1

[0031] according to Figure 5 , combined with figure 1 , The side of the airbag 1 in this embodiment is provided with a window hole 13 communicating with the liquid circulation channel 3, and the rest of the structure is as above.

[0032] The metal strip 12 of the present invention can be developed under X-ray to confirm that the direction facing the groove 4 in the treatment area is right in the direction of the opening of the target blood vessel. The liquid circulation channel 3 allows blood to circulate through the liquid circulation channel 3 after the balloon 2 is inflated, without blocking the blood flow at the distal end, and at the same time, the treatment area groove 4 can realize sealing in the treatment area of ​​the target blood vessel Drug administration achieves a good therapeutic effect while maximally retaining the blood flow supply of the distal tissue.

[0033] When the present invention is used, air is injected into the air bag 2 through the air intake co...

Abstract

The invention relates to a distal non-obstructive thrombolysis catheter. The distal non-obstructive thrombolysis catheter comprises a catheter main body and an air bag surrounding the catheter main body, wherein a liquid circulation channel which is vertically through is arranged on the middle portion of the air bag, a treatment area groove with closed periphery and an open side surface is formedin one side of the air bag, the catheter main body is fixed between the liquid circulation channel and the treatment area groove, and a medicine outlet is formed in the side, close to the catheter main body, of the treatment area groove; a ventilation pipeline and an administration pipeline are arranged in a side wall of the catheter main body, one end of the administration pipeline is connected with the medicine outlet, and the other end of the administration pipeline is provided with a medicine inlet hose; and one end of the ventilation pipeline communicates with the interior of the air bag,and the other end of the ventilation pipeline is provided with an air inlet control valve.

Description

technical field [0001] The invention relates to a thrombolysis catheter, in particular to a distal non-blocking catheter for thrombolysis and embolization. Background technique [0002] One: Thrombolysis [0003] 1. Cardiovascular disease is currently the number one cause of death worldwide. Vascular embolism is one of the common cardiovascular diseases. Common embolism sites include cerebrovascular, peripheral arteries, mesenteric arteries, etc., which have high disability and mortality rates. Currently, the commonly used treatment measures mainly include instrumental thrombectomy and drug thrombectomy. [0004] 2. Mechanical thrombectomy has the following disadvantages in the process of thrombectomy: 1) There are requirements for the diameter of the blood vessel, and blood vessels with too small inner diameter cannot be reached. 2) It may lead to refragmentation of thrombus and blockage of distal blood vessels. 3) It may further damage the vascular endothelium and caus...
