Foster Corporation has introduced LoPro Plus radiopaque compounds reinforced with nanoparticles for improved pushability of thin wall catheters. These compounds allow for extrusion of single layer tubes with radiopacity and strength properties equivalent to conventional two layer tubes, in which each layer provides the distinct properties. LoPro Plus reduces material and inventory costs when compared to standard two layer constructions.

Radiopaque compounds typically include 30% to 40% barium or bismuth filler to provide fluoroscopic visibility of catheters within blood vessels; however, these fillers are not designed to improve strength properties. Improved pushability and torque for catheters that must reach deep in the body or precise locations often requires coextrusion of additional layers using polymers with high strength properties. This can increase manufacturing costs due to the purchase and inventory management of multiple materials. LoPro Plus compounds combine radiopacity and strength enhancement in a single material designed to replace the two materials used for traditional extrusions.
