Introduction to Prosthetic Heart Valves
Introduction to Prosthetic Heart Valves – Heart Valves Coating – Cheersonic
The development history and trend of artificial heart valve: mechanical valve→biological valve→interventional valve.
Four heart valves: aortic valve, pulmonary valve, mitral valve, and tricuspid valve; the English abbreviations are: APMT, and the difficulty of research and development and the order of products are also: A→P→M→T
Heart valve surgery is divided into: open heart surgery (SAVR), minimally invasive valve surgery (MIVS), transcatheter valve intervention (TVT)
TAVR: Transcatheter Aortic Valve Replacement = TAVI: Transcatheter Aortic Valve Implantation
TPVR: transcatheter pulmonary valve replacement; RVOTD: right ventricular outflow tract defect; TAP: transannular repair
TMVR: transcatheter mitral valve replacement; TTVR: transcatheter tricuspid valve replacement
Ultrasonic spraying is uniquely suited for many medical coating applications due to its fine, non-clogging, repeatable spray performance and very low flow rate capability. For several years, Cheersonic has been providing ultrasonic spraying equipment for global medical equipment manufacturers. With the development of medical device technology, we will continue to design unique ultrasonic spraying solutions for medical coatings and provide high-quality medical device coatings on the market.
Cheersonic provides a variety of ultrasonic coating equipment and solutions for manufacturing industry of implantable, in interventional medical devices, the drug-eluting stents and balloon catheters. Our ultrasonic coating systems have been used to spray anti-restenosis drug eluting polymer solutions onto implantable stents. Compared to conventional two-fluid nozzles, ultrasonic nozzles can spray a more uniform drug coating that completely covers the stent without the orange peel and adhesion to a complex stent. And the coatings are much thinner than can be achieved with dip coating, saving spray material.
- Ideal for R&D and low-volume production
- Compact desktop design that is easy to move
- The material usage ratio > 95%
- Reliable, repeatable and consistent coating, uniformity of ±5%
- Max. length 100mm, max. diameter 60mm
