Problems solved by technology

[0006] The double-balloon thrombolytic catheter can solve various problems caused by drug thrombolysis and mechanical thrombectomy, but during the process of thrombolysis, the blood flow at the thrombus site must be blocked to ensure the concentration of drug release, which will also affect the human body. potential damage to health

[0030] see figure 1 , a double-balloon thrombolysis catheter of the present invention, comprising a catheter body 1 and a first balloon 21 and a second balloon arranged in sequence along the axial direction of the catheter body 1 on the outer circumference of the tip of the catheter body 1 22 , the second balloon 22 is close to the tip of the catheter body 1 , while the first balloon 21 is away from the tip of the catheter body 1 . The radial center of the catheter body 1 forms an inner lumen 10 . The axial direction of the lumen 10 is parallel to the axial direction of the catheter body 1 .

[0031] A first catheter-side lumen 11 and a second catheter-side lumen 12 , which are axially parallel to the axial direction of the inner lumen 1 , are also provided in the tube wall of the catheter body 1 . The second catheter side lumen 12 communicates with the first balloon 21 and the second balloon 22 .

[0032] The catheter body 1 is also provided with a catheter side hole 13 fo...

[0046] The difference between the second embodiment and the first embodiment is:

[0047] The first Y-shaped connector 4 is divided into a first main pipe 41 and a first bypass pipe 42 , the first main pipe 41 is sleeved on the radial outside of the catheter body 1 and connected to the tail of the sheath 3 . The dosing control valve 7 communicates with the first conduit side lumen 11 through the first bypass pipe 42 .

[0048] The second Y-shaped connector 5 is divided into a second main pipe 51 and a second bypass pipe 52. The second main pipe 51 is sleeved on the radially outside of the catheter body 1 and connected to the first main pipe 41 of the first Y-shaped connector 4. tail. The pressure control valve 6 communicates with the second conduit side lumen 12 through the second bypass pipe 52 .

Abstract

The invention discloses a dual-balloon thrombolysis catheter. The dual-balloon thrombolysis catheter comprises a catheter body as well as a first balloon and a second balloon which are sequentially arranged on the outer circumference of the tip part of the catheter body along the axial direction of the catheter body, wherein the second balloon is closer to the tip of the catheter body than the first balloon; an inner cavity channel, a first catheter side cavity channel and a second catheter side cavity channel which are parallel to the axial direction of the catheter body are arranged in the catheter body; the first catheter side cavity channel is communicated with a medicine adding control valve; the second catheter side cavity channel is communicated with a pressure control valve, the first balloon and the second balloon; and the catheter body is provided with catheter side holes which are positioned between the tail end of the catheter body and the first balloon and are used for enabling the inner cavity channel to be communicated with the outside, and medicine adding micro-holes which are positioned between the first balloon and the second balloon and are used for enabling thefirst catheter side cavity channel to be communicated with the outside.

Description

technical field [0001] The invention relates to a double-balloon thrombolysis catheter in the field of medical instruments. Background technique [0002] Vascular embolism is a common disease in cardiovascular diseases, such as cerebrovascular ischemic stroke, etc., and its disability rate and mortality rate are extremely high. At present, the treatment methods for such diseases mainly include drug thrombolysis and mechanical thrombectomy. [0003] Judging from the effect of current clinical treatment, the effects of drug thrombolysis and mechanical thrombectomy are not very satisfactory. [0004] The main problem with drug thrombolysis is the need for systemic administration, which can easily lead to hemorrhagic complications. And during the process of thrombolysis, the size of the embolus shrinks and it is easy to block the downstream capillaries with smaller diameters. [0005] The main problem of mechanical thrombectomy is that it is easy to destroy the emboli when th...
