MediCoat PSI
Integrated Ultrasonic Stent Coating System
The MediCoat™ PSI offers the same cutting-edge precision stent coating features as Sono-Tek cardiac stent coating machines, with a unique design making the system ideal for coating large peripheral stents. The system incorporates Sono-Tek's MicroMist ultrasonic nozzle with stent motion abilities that allows for complete stent coverage of large vascular peripheral stents. Sono-Tek Corporation has over 30 years of expertise in ultrasonic spray technology and the most advanced proven stent coating systems on the market, as well as systems for coating guide wires and catheters.
The MediCoat PSI is an advanced adaptation of our proven MediCoat DES benchtop stent coating system. It uses the same established method for coating peripheral arterial stents that is commonly used in coating cardiac stents. For manufacturers looking to implement the practice of coating peripheral arterial stents with polymer drug compounds, this new advanced area of stent coating has shown great promise in the industry.
- Small ultrasonically generated drops provide excellent penetration and inhibit webbing
- Fully integrated continuous flow polymer delivery system provides the highest degree of accuracy
- Integrated control of the nozzle, liquid delivery, and stent motion
- Large viewing windows in front and on top of coating chamber
- Easy access side door and illuminated sealed spray chamber
- Easy access side door and illuminated sealed spray chamber
- User-friendly stent loading rods
- Minimal overspray (minimal waste)
- Self-cleaning ultrasonic nozzle prevents clogging
- Automated self-cleaning function
- Capable of delivering multiple polymers (layering)
- All system components are compatible with the typical solvents and polymers used in stent coating (solvents such as: THF, acetone, DMAC, toluene, chloroform polymers: urethanes, polylactides, polycarbonates, silicones, styrenes)
Operating Principle
The MediCoat™ PSI Benchtop Stent Coating system combines Sono-Tek's unique microspray atomizing nozzle with low pressure gas to produce a soft, highly focused beam of atomized spray drops. Compressed gas, typically at 1 psi, is introduced into the diffusion chamber of the air shroud, producing a uniformly distributed flow of air around the nozzle's atomizing surface.
The ultrasonically produced spray created is immediately entrained in the air stream.An adjustable focusing mechanism on the air shroud allows complete control of the spray width.
The customer has the option of attaching a custom stent holding device onto the rotating mandrels. Stents are rotated at a fixed speed, controlled by the user. The stent moves horizontally side-to-side beneath the target area. The number of horizontal passes made are programmable.
A low-velocity exhaust maintains a negative air pressure to assure that any unwanted mist beyond the target area is removed.
The system's unique glove box design allows for safe and convenient access to the stent load and unload area. Large,unobstructed viewing windows and high-intensity internal LED lighting allow for easy observatio
With integrated controls for triggering the ultrasonic atomization, liquid delivery and stent movement, the MediCoat™ PSI Stent Coating System provides a complete solution for developing a stent coating process and moderate volume production.
