Tristar Plasma Treats Polymer Components

Tristar is able to plasma treat, or 'superclean', catheter suppliers' polymer components before they apply a lubricious coating to the devices. By first super-cleaning the polymer, the company can alter the components' surface properties to improve adhesion and biocompatibility.

The process also allows for better acceptance of time-released medications used during surgery and recovery. Tristar uses a plasma chamber to carefully control the gas type, flow, pressure and concentration to ensure a uniform, three-dimensional surface treatment. The process is also used to treat other medical devices, including drainage tubes, endoscopes, stents and intra-ocular lenses.
