Ultrasonic Drug Eluting Stent Spraying
Ultrasonic Drug Eluting Stent Spraying – Cheersonic
The drug-eluting stent carries the drug through the polymer coated on the surface of the metal stent. When the stent is placed in the site of the vascular lesion, the drug is released from the polymer coating by controlled release of the drug to the vascular wall tissue through the elution mode to exert the biology effect.
Surface-coating techniques used in drug-eluting stent fabrication equipment and manufacturing processes have important implications for the efficacy of drug-eluting stents. Conventional coating preparation processes, such as weather deposition, magnetron sputtering, plasma deposition and the like generally require expensive equipment and are not conducive to mass production of the stent.
CHEERSONIC applied the principle of ultrasonic atomizing spraying to the coating preparation process of drug-eluting stent, developed a set of ultrasonic spraying equipment and improved the integration of a new drug release stent spraying equipment – ultrasonic medical spraying equipment.
The commonly used stent coating technology can be ultrasonic coating, which sprays polymer and drug solutions (using various solvents) onto the stent, so that a uniform drug release layer can be uniformly deposited on the surface of the stent. Ultrasonic nozzles have the advantage of penetrating complex stent geometries, ensuring complete coverage of all pillar surfaces without the need for webbing. The soft atomized spray can adhere well to the surface, and the morphological characteristics of the coating can be adjusted by modifying the process parameters. The advantage of the ultrasonic spraying system is that the coating formed by dip coating is much thinner, can save spraying materials to a large extent, and the nozzle is not easy to be blocked.
UAM3000 is a high-performance stent spraying equipment developed for stent series products, mainly used for drug coating on the surface of stents. The special nozzle for ultrasonic stent with national patent can realize accurate application of medicine, and the fixture specially equipped for stent is convenient for loading and unloading. This device has the characteristics of supporting multiple series and multiple types of stents, high drug utilization, accurate drug delivery, and high uniformity of the stent membrane layer.
