Abstract

The invention relates to systems and methods of using the systems to fabricate thin wall tubing for use in medical devices. Some embodiments provide high density polyethylene tubing with an inner diameter of about 7 French to about 13 French (0.015 inch to 0.168 inch), and with a wall thickness between about 0.0015 inch to about 0.0025 inch. Embodiments of the tubing may be used as a liner for the fabrication of catheters that have an outside diameter in the range of about 9 to about 15 French. Embodiments of the tubing are fabricated with a zoned gas cooling tunnel that provides a precisely controlled and circumferentially homogeneous gas flow around the cooling extrudate. Gas flow into the tunnel is controlled with high precision by a flow controller; gas flow within the tunnel is independently controlled in each zone, gas flow within the interior of the runnel zones is controlled by a pattern and alignment of gas flow inlets and a common exhaust.
