The mechanical properties of guidewires

Part III: Sliding friction
  • Jürgen Schröder
Technology Assessment

Abstract

Stiffness is always one of two factors that determine frictional resistance. The other factor, the coefficient of friction, depends on the surface characteristics. Teflon coating reduces the sliding friction to one-half, and a hydrophilic plastic coat to about one-sixth compared with steel.
