Artificial Blood Vessel Barrier Artificial Blood Vessel Barrier - Medical Device Coatings - Cheersonic According to industry insiders, the manufacture of artificial blood vessels involves dozens of procedures, and both textile technology and collagen coating have technical barriers that are difficult to break through. 1. The structure of blood vessels Human arteries are composed of three layers of intima, media and adventitia. Blood vessels of different diameters and [...]

Wafer Oxidation Wafer Oxidation - Photoresist Spray System - Cheersonic The role of the oxidation process is to form a protective film on the wafer surface. It protects wafers from chemical impurities, prevents leakage currents from entering circuits, prevents diffusion during ion implantation, and prevents wafer slippage during etching. The first step of the oxidation process is to remove impurities and pollutants, and it is necessary to remove [...]

Balloon Catheter Hydrophilic Coating Curing Method Balloon Catheter Hydrophilic Coating Curing Method - Ultrasonic Sprayer - Cheersonic After the balloon catheter enters the body, it will cause a series of reactions. For example, vascular endothelial damage and adsorption of bacteria due to catheter friction. In order to reduce the damage of the balloon catheter to the human body during interventional treatment and improve its surface biocompatibility and lubricity, [...]

Balloon Catheter UV Curing Process Requirements Balloon Catheter UV Curing Process Requirements - Balloon Catheter Coating - Cheersonic According to the theoretical basis and experimental analysis of the UV curing process of the balloon catheter, in order to obtain a good curing effect of the hydrophilic coating on the medical catheter and meet the needs of the use of the balloon catheter, the following UV curing process requirements [...]

What is heart valve disease? What is heart valve disease? Drug coating technologies - Cheersonic The heart can be compared to a house, each chamber is like a separate room, and the valve is the door of the room. Heart valves are divided into atrioventricular valves and arterial valves. The atrioventricular valve is the "door" that connects the atrium to the ventricle, the mitral valve that connects the [...]

Artificial Heart Valve Replacement Artificial Heart Valve Replacement - Prosthetic Heart Valve Biocoating - Cheersonic Heart valves are the basic structure of the heart, and severe valve disease can lead to death. Heart valve refers to the valve between the atrium and the ventricle or between the ventricle and the artery. Its main function is to prevent the backflow of blood and ensure the flow of blood from [...]

When to choose a drug balloon? When to choose a drug balloon? Balloon Catheter Coating System - Cheersonic We all know that the implantation of coronary stents is an important means of treating coronary heart disease. Generally speaking, the coronary arteries with severe stenosis (more than 70%) are expanded, and then stents are implanted to support the stenosis and restore lumen patency. However, not all cases are suitable [...]

Drug Balloon Delivery and Release Drug Balloon Delivery and Release - Balloon Catheter Coating System - Cheersonic The drug balloon rapidly releases anti-proliferative drugs to the blood vessel wall through balloon expansion, which can achieve the ultimate concept of "intervention without implantation" in the treatment of coronary stenosis. The safety and efficacy of drug balloons in stent stenosis and small blood vessels have been well verified. At present, [...]
