What are the 3 coronary stents that you don't know yet? 3 Coronary Stents - Medical Stent Coating - Cheersonic Patients often ask: "Doctor, what material is the coronary stent implanted in my body? Should I replace it? Will it fall out?" For the commonly used clinical drug stents and bare stents, these two types of stents are all metal stents, and the materials are all metal, including [...]

The Misunderstanding of Coronary Stent The Misunderstanding of Coronary Stent - Medical Stent Coating - Cheersonic The heart is the engine of the human body, providing blood and nutrients to various organs of the human body, and our heart itself also needs blood and nutrients, which are provided by the coronary arteries. The popular understanding of coronary heart disease is that the blood vessels supplying the heart are [...]

The past and present of coronary stents The past and present of coronary stents - Medical Device Coating - Cheersonic Percutaneous coronary intervention (PCI) is one of the main treatment methods for coronary heart disease. The advent of coronary stents has changed the history of coronary heart disease treatment. The medical sages have developed coronary stents to this day with their persevering spirit of exploration. 1. "Past Life" [...]

Cardiac stent laser process Cardiac stent laser process - Medical Device Coating - Cheersonic Cardiac stents first appeared in the 1980s, also known as coronary stents. The diameter of the cardiac stent is only 2-4 mm and the weight is less than one ten thousandth of a gram. It is a more direct and effective tool to deal with acute myocardial infarction. It can reach the blocked coronary [...]

Basic Technical Requirements For Balloon Catheters Basic Technical Requirements For Balloon Catheters - Medical Coating - Cheersonic Balloon catheters are divided into balloon dilatation catheters, balloon occlusion catheters and balloon remodeling catheters. Balloon dilatation catheter is a flexible catheter with an inflatable balloon at the head, which is used to dilate narrow hollow organs in the human body under image guidance, such as blood vessels, digestive tract, urinary [...]

Degradable Polymer Occluder Degradable Polymer Occluder - Medical Device Surface Coating - Cheersonic The traditional treatment for congenital heart disease is open thoracic surgery, which can cause severe trauma to the patient. With the development of interventional medicine, there are currently 5 types of occluders on the market for the interventional treatment of congenital or structural heart diseases - atrial septal defect occluder, ventricular septal defect occluder, soft [...]

Coronary Stent Coronary Stent - Medical Device Coating - Cheersonic Coronary heart disease is the abbreviation of coronary atherosclerotic heart disease, which is usually caused by coronary atherosclerosis leading to stenosis or obstruction of the vascular lumen, or myocardial ischemia, hypoxia or necrosis caused by coronary functional changes (spasm). . Coronary stent is an intravascular supporter made of metal or polymer material, which can be sent to the [...]

Different characteristics of PTCA balloon Each company's PTCA balloons have various characteristics, such as balloon size, materials used, construction, and compliance of the balloon to the vessel lumen. Depending on the location and severity of the lesion, PTCA is required to have different properties and characteristics. PTCA balloons are divided into compliant, non-compliant and semi-compliant balloons according to their compliance. Semi-compliant PTCA balloon for pre-dilation of lesions before [...]

Optimizing Second-generation Drug-eluting Stents Optimizing Second-generation Drug-eluting Stents - Spray Coater - Cheersonic In order to solve the problem of late thrombosis risk, after 2006, the second generation of drug-eluting stents embarked on the road of comprehensive optimization, mainly from the three aspects of stent platform, drug and coating. Optimization 1. Optimization of the bracket platform: Nickel-titanium alloy or cobalt-chromium alloy and other alternatives to stainless steel have [...]
