January 15, 2020 - Nordson MARCH introduced the PROGENY plasma treatment system with a chamber that is 2 meters deep with overall dimensions of 660mm W x 2260mm D x 660mm H for plasma treatment of catheters at their full extended length. Plasma cleans and activates the surface prior to applying a lubricious coating and provides adhesive bonding of the balloon to the catheter. It removes contamination, impurities, and organics at the nanometer level and improves surface wettability, hydrophilicity, and bonding capabilities to address issues such as poor wetting, poor coating uniformity, voids, and poor adhesion.

The PROGENY system provides plasma treatment at 13.56 MHz and accommodates all the common gases, like oxygen, nitrogen, and argon, with high process reproducibility and uniformity. An EPC controller with SECS/GEM interface facilitates remote control of the equipment and real-time data logging. The system is controlled by an intuitive touch screen GUI with a one-button start feature. Also included are configurable plasma cells with high flux electrodes and direct gas injection for uniform gas flow. Besides catheters, PROGENY systems can plasma-treat other products with part surfaces up to 2 m long and 50 cm wide that need better wetting, coating, and adhesion.

The PROGENY system's two front- and back-loading doors, horizontal electrode design, and integrated rack allow for loading of various size products, provide alignment for extended catheters, and deliver uniform plasma treatment. With the integrated rack, product trays slide in and correct spacing and positioning of the catheters between each electrode pair is maintained.

Features include an integrated gas distribution system for uniform gas flow, water-cooled high flux electrodes, a removeable product tray, a controlled vacuum exhaust, and an electrode assembly for chamber maintenance. Temperature-controlled electrodes ensure consistent process repeatability.
