Plasma Treatment of Medical Plastics

October 23, 2014

Surgical catheters can slide and maneuver more easily within the body after plasma treatment.  We’ve had many calls recently from the medical community; both medical device and pharma manufacturers seeking to modify their plastic components in their quest to deliver better patient outcomes. And it is truly amazing how simply altering the surface properties of components via vacuum plasma can enhance medical and scientific applications. Surgical catheters, for instance, can slide and maneuver more easily within the body after plasma treatment. And the timed-release of drugs via PEEK and PVC tubes can be achieved more easily after plasma.

This week on Tech Talk we wanted to help you evaluate if plasma treatment is the right choice for your medical application.
