Radel®polyphenylsulfone (PPSU) resin from Solvay Specialty Polymers USA, LLC, is known for its durability, light weight, easy formability, and exceptional sterilizability. RiverTech Medical, a Vention Medical Company, based in Chattanooga, Tenn., has precision micro-tubing with variable flexibility for catheter-based medical devices. The micro-tubing offers two to three different stiffnesses and flexibilities within one tubing component for catheter-based medical device procedures such as angioplasty, stent placements, and thrombectomy. 

There is a significant need for varying stiffness in catheter designs to allow for optimum flexibility while maintaining the stiffness required to track the catheter to its desired location. In order to achieve ideal performance and processing, the product is comprised of a layer made of Radel®polyphenylsulfone (PPSU) resin from Solvay Specialty Polymers.
