Abstract
The present invention provides a method for fabricating flexible medical tubings including the steps of providing a polymeric material, forming a tubing from the polymeric material, the tubing having a longitudinal axis and an initial diameter, and orienting the tubing along the longitudinal axis of the tubing to reduce the diameter of the tubing to define an oriented diameter.
