Ultrasonic Atomization For Drug Eluting Stents

Major advances have been made in the past few decades in the percutaneous treatment of artery diseases. The development of each new technology has been spurred by the downfall of the previous technology. Balloon angioplasty emerged as a minimally invasive solution to previous treatment methods which typically involved significant opportunity for complications. This treatment method came with its own disadvantages due to its inability to prevent vessel recoil and neointimal proliferation. Intracoronary stenting through Bare Metal Stents overcame the acute recoil of balloon angioplasty, but was unable to prevent the occurrence of in-stent-restenosis caused by excessive neointimal proliferation. Drug Eluting Stents utilize agents that effectively reduce the occurrence of this neointimal proliferation and increase or eliminate the time needed for subsequent treatment. The agents consist of an antiproliferative drug and a specially designed polymer coating to control the release profile of the drug over time. Ultrasonic Atomization technology has proven successful in the application of these agents on to Drug Eluting Stents.

The UAM3000 Ultrasonic Stent Coating System is 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 Stent Coating System 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.
