Surface modification can optimize medical device performance, safety and biocompatibility. For many applications, surfaces are often modified to impart anti-thrombogenic, antimicrobial, anti-fouling or lubricious properties. Hydrophilic or hydrophobic coatings can however be associated with manufacturing, cost and durability challenges. Surface modifying additive technologies can offer a simpler solution to overcome such challenges while achieving low friction surfaces.
- Surface modifying macromolecule (SMM) additive technology is an alternative surface modification technique to coatings or co-extrusions
- While mainly used to improve the blood compatibility of devices, the Endexo® SMM chemistry can also impart low surface friction
- The integrated nature of an additive-based surface modification technique ensures a durable surface effect able to withstand fluid flow exposure and mechanical forces.
- The SMM can provide simultaneous functional properties such as reduced friction, anti-thrombotic properties, or antifouling properties
