However, there are still many problems with this technology. For lesions with severe calcification, sometimes 10 to 15 atmospheres of pressure are required to pre-expand the blood vessels, and sometimes even 30 atmospheres of pressure are required. The result of such high pressure will inevitably cause the calcified plaque to decompress the stress. Transfer to the inner wall of the blood vessel, causing blood vessel damage, and in severe cases, causing blood vessel dissection or perforation
In addition, for lesions that have been successfully implanted with stents, clinical studies have shown that the long-term restenosis rate remains high, because the stent is a foreign substance, and the continuous stimulation of the vascular intima will lead to intimal hyperplasia, which in turn causes Vascular restenosis occurs

Embodiment 1
[0051] as attached figure 1 and 2 As shown, a blood vessel recanalization system for cardiovascular stenosis, the main components include a balloon 1 , an energy generation controller 3 , and a catheter 4 .
[0052] In one embodiment, a blood vessel recanalization system for cardiovascular stenosis includes an energy generation controller 3 , a handle 2 , a catheter 4 , a balloon 1 and a guide wire 5 .
[0053] The handle 2 is connected to the energy generation controller 3 through a connection line 15, and the handle 2 and the energy generation controller 3 are respectively provided with a first connection line and a second connection line, and the first connection line and the second connection line The connecting wire is fixedly connected through the connecting plug 14 .
[0054] The energy generation controller 3 can emit and regulate ultrasonic waves of a specific frequency, so that the electrode pairs 104 form cavitation bubbles to generate shock waves.
[0055] The h...
Embodiment 2
[0091] Based on the above-mentioned embodiment 1, the similarities will not be repeated, and the difference is that, as attached Figure 9 As shown, the balloon 1 also includes an outer tube 107, the electrode pair 104 is respectively arranged on the inner tube 102 and the outer tube 107, the electrode wire 105 is welded on the electrode pair 104, and attached to the inner tube 104. The outer surface of the tube 102 to the inside of the outer tube 107 .
[0092] The distal outlet of the outer tube 107 and the inner tube 102 form a medium liquid outlet 108, so that the medium liquid can be injected into the perfusion balloon 1 from the handle 2 section.
[0093] Wherein, the two electrode pairs 104 are on the inner tube 102 and the outer tube 107 respectively, since the position of the outer tube 107 can be controlled by the handle 2 to move axially, so that the distance between the two electrode pairs 104 can be adjusted.
[0094] Preferably, when the distance between the ele...

Abstract
The invention relates to a vascular recanalization system for cardiovascular stenosis lesions. The vascular recanalization system comprises a balloon, an energy generation controller and a catheter. The catheter comprises a main body tube, one end of the catheter is connected with the energy generation controller, and the main body tube at the other end of the catheter is connected with one end ofthe balloon; wherein the balloon mainly comprises a balloon main body, an inner tube and an electrode pair, and the inner tube is arranged in the balloon main body; and the energy generation controller can send out and regulate a vibration signal with a specific frequency to enable the electrode pair to generate a vibration wave. The system further has a drug delivery function, can inhibit increase of endovascular membranes after recanalization and avoid restenosis after recanalization, thereby achieving the function of long-term treatment of stenotic lesions. For many vascular diseases needing to be implanted with stents, the purpose of achieving long-term patency rate without stent implantation is achieved, and therefore real intervention implantation-free is achieved.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a blood vessel recanalization system for cardiovascular stenosis. Background technique [0002] Cardiovascular stenosis refers to human arteriovenous blood vessels, including coronary arteries, peripheral blood vessels, and intracranial blood vessels. Due to abnormal lipid metabolism, lipids in the blood are deposited on the smooth intima of blood vessels, and gradually accumulate into atherosclerosis. Lipid plaques, as time goes by, these plaques increase or even calcify, causing narrowing of the blood vessel lumen, blocking blood flow, leading to downstream blood vessel and body ischemia, and corresponding clinical manifestations. If the stenosis occurs in the coronary artery, it will cause palpitations, chest pain, dyspnea, and angina pectoris. In severe cases, it will lead to myocardial insufficiency or myocardial necrosis; if it occurs in the periphery, it will cau...
