Overview

Creating reactive surfaces to generate robust adhesive bonds

  • Atmospheric plasma cleans and activates by removing organic contamination and creating reactive surfaces to generate robust adhesive bonds
    • Uses low voltage RF power to safely generate plasma; safe enough to be handheld
    • No NOx species are generated (low EH&S risk)
  • Water-cooled head allows treatment of catheters, membranes, and other thermally sensitive products
  • Safe for use on implantable devices
    • Stent
    • Drug delivery
    • Central venous catheters
  • Cleanroom compliant

Tubing

Medical grade catheters

  • Medical grade catheters are highly non-reactive, presenting challenges during bonding to other components, such as hubs and ports.
  • Printing: Ink wets out and adheres to catheters after treatment, providing durable branding and part labeling
  • Coating: After plasma activation, applied coatings adhere better to the polymer surface
  • Non-thermal plasma: Actively water-cooled plasma sources prevent damage of thin-walled, thermally sensitive catheters and balloons

Coatings

Manufacturing line activate prior to coating

  • Surfx plasma systems are used in manufacturing lines to activate surfaces prior to coating:
    • Drug-eluting devices
    • Stents
    • Balloons
    • Diagnostic chips
  • Works with a variety of coating methods: dip, spray, and ultrasonic
  • Improved adhesion of different types of coating:
    • Silane coupling agents (SCA) for hydrophobic or hydrophilic surfaces
    • Proprietary coatings

Cell Adhesion

Improving cell adhesion with Surfx Plasma

  • Treating microplates with Surfx plasma improves cell adhesion.
    • Reactive gas flows into wells, activating the entire surface without damage
  • Increased cell adhesion improves:
    • Enzyme-linked immunosorbent assays (ELISA)
    • Cultures
    • Tumor growth
