Abstract

The present invention provides a method for using medical tubing for infusing therapeutic fluids to a patient comprising the steps of: providing a medical tubing having a sidewall of a polymeric blend, the blend having a polymeric material in an amount by weight within the range of 99.999%-90.0%, and an additive in an amount by weight within the range of 0.001%-10%, the tubing having been oriented along a longitudinal axis of the tubing to define a oriented diameter that is less than a diameter of the tubing before orienting; and providing fluid under pressure through the tubing to the patient.
