Abstract
A radiopaque, optically translucent thermoplastic polyurethane compound is disclosed. The use of nano-sized particles of barium sulfate optionally in combination with a minor amount of certain dispersion aids allows the barium sulfate to be sufficiently dispersed within the thermoplastic polyurethane to retain optical translucency according to a defined Haze Determination Test. Medical devices, needing both visual spectrum observation before and during in-vivo medical use and radiopacity monitoring during in-vivo medical use, benefit from this compound. Optionally, a surface enhancer can also be used.
