Abstract

A thermoplastic polyurethane chain extended with an alkylenediol is blended with a thermoplastic polyurethane chain extended with an oxyalkylene glycol oligomer. The blend is extruded into a catheter tubing having sufficient initial stiffness for satisfactory insertion in a patient and a high degree of softening for safe positioning and long term catheterization procedures without the risk of vessel wall perforation.
