ABSTRACT:
Medical tubing is extruded from a composition of a divalent metal ionomer, polyamide and polyurethane, preferably in the ranges of 60-80% of ionomer, 10.gtoreq.25% polyamide and 10-20% polyurethane. After extrusion the tubing may be sterilized with ethylene oxide or gamma irradiation. The tubing is substantially kink-resistant and the degree of stiffness and mechanical strength can be adjusted by varying the amount of polyamide and polyurethane so that the tubing can efficiently function as a catheter.
