Description

Shockwave balloon with positioning feedback TECHNICAL FIELD

[0001] The present application relates to the technical field of shockwave balloon bodies, in particular to a shockwave balloon with positioning feedback. BACKGROUND

[0002] Cardiovascular stenosis refers to the deposition of lipids in the inner membrane of the originally smooth blood vessels due to abnormal lipid metabolism in the body's arteriovenous vessels, including coronary, peripheral, intracranial and other blood vessels. The lipids gradually accumulate into a yolk-like lipid plaque, and with the passage of time, the plaque increases and even calcifies to cause stenosis of the blood vessel lumen,

[0003] which blocks blood flow, leading to ischemia of downstream blood vessels and the body, and producing corresponding clinical manifestations. Vascular calcification is one of the manifestations of atherosclerosis, hypertension, diabetes, vascular disease, chronic kidney disease, aging and other common pathological manifestations. In the past, people have always believed that vascular calcification is a passive, degenerative and inevitable terminal process. However, with the increase of clinical and basic research in recent years, it has been confirmed that vascular calcification is actually a process similar to bone development and cartilage formation, and is an active, adjustable, preventable and treatable process. The main manifestations are increased vascular wall plasma and decreased compliance, which can lead to myocardial ischemia, ventricular hypertrophy and heart failure, and severe plaque rupture and thrombosis, which is one of the important causes of high incidence of heart and brain blood vessels and high mortality. It is also an important marker for the occurrence of atherosclerotic vascular events, stroke and peripheral vascular disease.

[0004] Percutaneous coronary intervention refers to the use of catheter technology to unblock the stenosis or even occlusion of the coronary artery lumen, thereby improving the blood perfusion of the myocardium. Its technical classification mainly includes percutaneous coronary balloon angioplasty, coronary stent implantation, coronary rotational atherectomy, cutting balloon angioplasty and intracoronary thrombus aspiration, etc. Intravascular shock wave lithotripsy (ISL) has been applied in clinical practice abroad in recent years as a newly developed medical technology. When using the shock wave balloon (also known as the shock wave balloon body), the shock wave balloon is first delivered to the calcified lesion site of the blood vessel, then the shock wave balloon is dilated at low pressure, and finally a high-pressure pulse power is released to the shock wave balloon to generate intermittent shock waves, which can crush the superficial and deep calcified plaques in the blood vessel lumen, so as to achieve the purpose of fully expanding the blood vessel lumen and significantly improving the compliance of the blood vessel. As an effective instrument for treating vascular calcification, the shock wave balloon can effectively remove calcified lesions and has the advantages of less trauma and fewer complications.

[0005] When the shock wave balloon body is in use, the device is usually positioned by using a camera, and when the device enters the blood vessel of the patient, the mucus in the blood vessel is easily adsorbed on the surface of the positioning camera detector, causing the positioning camera detector to be relatively blurred, affecting the positioning effect of the device, and when the shock wave balloon body is in use, due to the different sizes of the lesions, the size of the lesions of the patient is not consistent when the shock wave balloon body is used to treat the lesions of the patient, affecting the treatment effect of the device.
