ABSTRACT:
An introducer, such as for an endotracheal tube, comprises a solid rod made of an aliphatic polyurethane containing about 20% barium sulphate. The hardness of the material is about 60 Shore D so that the introducer is resilient within a range of deformation and beyond this range it is bendable into a set shape that only resumes its original shape at a slower rate.
