Does the heart stent have a life span?

Does the heart stent have a life span?

Coronary heart disease is the appearance of plaque in the coronary arteries, which narrows the lumen of the blood vessels, resulting in myocardial ischemia and chest pain.



When performing cardiac stent surgery, first use a balloon catheter to expand, flatten the plaque in the blood vessel, and expand the blood vessel at the same time. Then the heart stent is placed. The stent will stick the plaque to the wall of the blood vessel and maintain the size of the blood vessel cavity to prevent the blood vessel from narrowing again due to elastic retraction. The stent and the vascular intima are tightly combined. Subsequently, the endothelial cells on the intima of the blood vessel will slowly grow and gradually cover the stent trabeculae. Eventually, the stent is integrated with the vessel wall. Therefore, there is no such thing as a "lifespan" for heart stents, and heart stents do not need to be replaced every few years. This is a big misunderstanding.

Ultrasonic Stent Coating Systems

The CMED-S Ultrasonic Stent Coating Systems are a precision spraying system designed for anti-restenosis drug polymer that provides a uniform and non-adhesive drug coating to the cardiac stents through ultrasonic spray technology. Ultrasonic spraying can penetrate stents of different geometries, ensuring complete coverage of all of the strut surfaces of the stent without webbing. With a special fixture design, the entire stent can be sprayed for a maximum of 50mm stent spraying. Cheersonic has extensive experience in the surface coating of implantable medical devices such as drug stents and balloons to provide customers with complete solutions.

Spray On Fabric Coating – Ultrasonic Sprayer Atomizing System

  Spray On Fabric Coating Spray On Fabric Coating – Ultrasonic Sprayer Atomizing System Ultrasonic spraying machine  using ultrasonic nozzle technology, can produce very small, uniform droplets, with a very tight droplet distribution. Compared with the pressure nozzle, the nozzle orifice is large and is designed to be a non-clogging pressure-free spray device. This makes the ultrasonic sprayer flow rate controllable range is large, and ultrasonic spraying machine can prepare a very uniform very thin coating, saving spraying materials and improve the quality of fabric coating, through a more uniform coating to deal with the performance of the product.

Drug Eluting Stents Coating

Drug Eluting Stents Coating Drug Eluting Stents Coating – Ultrasonic Spray System – Cheersonic The drug-eluting stent is a stent that uses the bare metal stent platform to carry (load) anti-vascular intimal hyperplasia drugs, which are eluted and released locally in the blood vessel, which effectively inhibits the stent intimal hyperplasia and prevents restenosis in the stent. The effective application of drug-eluting stents can greatly reduce the incidence of restenosis and re-intervention, but it does not reduce the mortality rate. There is no significant difference in the incidence of clinical endpoint events between different drug-eluting stents, and some secondary endpoints can benefit from it. Drug-eluting stents include bare stents made of stainless steel or cobalt-chromium. These stents are covered by drug carriers with anti-proliferative effects. The polymer drug-loading coatings include permanent, degradable and polymer-free drug-loading coatings. Layer technology, the conta...
