Surface Active Systems
Introduction to Surface Active Systems
Surface Active Systems is a groundbreaking new category of biocompatible surface coatings for medical devices.
These durable coatings improve the devices’ longevity and safety, meaning they perform effectively over long periods of time.
The innovative polymer-based coatings are suitable for a wide variety of medical components, from tiny metal implants to larger devices.
Implants perform better, while patients recover more quickly and can have an enhanced quality of life.
The category comprises the product ranges Surface-Active Therapeutics and Surface-Active Materials.


Introduction to Surface-Active Therapeutics
Surface-Active Therapeutics are advanced surface coatings that, unlike traditional solutions, remain active on the device surface without releasing active ingredients.
The coatings present less risk to patients than conventional drug-based options, which they are designed to complement or replace.
These treatments address clinical challenges such as thrombosis, fibrin sheath formation, and infection. A durable, polymer-based barrier improves the performance of the device while safely delivering long-lasting therapeutic value.
The current Surface-Active Therapeutic solutions are AstutePlus and TridAnt.

Introduction to Surface-Active Materials
Surface Active Materials are robust surface treatments ideal for use in demanding environments where devices are subjected to friction, movement and stress. The coatings maintain their integrity under expansion, movement, bending, and sterilisation.
Built with the same platform concept as Surface-Active Therapeutics coatings, these durable surfaces improve the devices’ biocompatibility and mechanical activity. As a result, devices coated with these treatments perform better and more consistently over time.
