MEDICAL DEVICE WITH EXTRACTED ELEMENT OF HEALTH ORIENTATION

摘要

The present invention relates to an elongate polymer member (100) having molecular helical orientation formed by rotation immediately after passing through the extrusion head (20). The elongate polymer member (100) is rotated downstream of the extrusion head (20) in the molten state prior to solidification in order to impart the molecular helical orientation. Rotating the polymer member (100) in the molten state allows the helical orientation to be imparted at the molecular level, and allows for more rotations per lineal foot of extrusion.
