Intravascular interventional therapy is a minimally traumatic treatment method by opening tiny channels in the skin and blood vessels without exposing the lesion. After more than 30 years of continuous development, balloon dilatation catheters are mainly used in percutaneous transluminal angioplasty, vascular stents, and thrombolytic therapy.
1. How to use the inflation device for angioplasty?
The blood vessels provide a constant flow of oxygen-rich blood to the organs. In diseased blood vessels, blockages may form, which can reduce blood flow to the organs and cause adverse clinical symptoms and even death. Diseased blood vessels can include a range of substances from early thrombosis to late calcified plaques.
Angioplasty is a catheter-based surgery performed by a doctor to open a blocked blood vessel and restore blood flow. For example, the access site can be opened in the patient's groin, arm or hand, and the guide wire and catheter can be advanced to the blocked position under fluoroscopic guidance. The catheter with a small balloon adjacent to its distal end can be advanced under fluoroscopic guidance until the balloon is located in the narrow area. The balloon can then be inflated and evacuated one or more times by the angioplasty inflator to expand the narrowed area of the artery.
The inflation device for angioplasty can release embolic particles downstream from the stenosis. These embolic particles may lead to unfavorable clinical results. It has been shown that it is advantageous to capture these embolic particles to prevent them from following the blood flow down to the capillary bed. In addition to balloon angioplasty, stents and mechanical atherectomy can also be used.
2. What interventional procedures can the inflation device for angioplasty be used for?
The most commonly used interventional treatments are balloon dilatation (PTCA) and stent placement.
Balloon dilatation (PTCA) is a method in which the balloon is delivered to the lesion of coronary artery stenosis, and the angioplasty inflator is used to pressurize the balloon to expand the balloon and squeeze the narrowed plaque, so that the lumen is enlarged and the blood flow is smooth.
Stent implantation is to send the stent to the vascular lesion, and use an angioplasty inflator to lift the pre-installed balloon to open the artery, keep the lumen unobstructed, improve myocardial blood flow, and relieve chest pain. Treatment of symptoms. This is the current method commonly used in coronary interventional therapy.
There are two types of stents: bare metal stents and drug stents.
Bare metal stents are regular interventional devices. Most of them are synthetic metal materials, which have the function of supporting and retracting blood vessels. Bare metal stents can squeeze the thrombus and stick to the intima of the blood vessel to reduce the acute occlusion of the blood vessel, but it is prone to the risk of restenosis.
Many diseases can be treated by interventional techniques, such as coronary heart disease, peripheral vascular disease, congenital heart disease, valvular disease, and arrhythmia diseases.
Nowadays, Lepu Medical has developed into a world-leading medical technology company in the fields of cardiovascular intervention, structural heart disease, heart rhythm management, anesthesia and intensive care, in vitro diagnostics and general surgery.
