Abstract: The present invention provides a method for fabricating a medical tubing. The method includes the steps of: (1) providing a material selected from the group consisting of ethylene homopolymers and ethylene copolymers, wherein the ethylene copolymers are obtained by copolymerizing ethylene with a comonomer selected from the group consisting of lower alkyl olefins, lower alkyl esters of a carboxylic acid and lower alkene esters of a carboxylic acid, the lower alkyl and lower alkene each have from 3-18 carbons, or blends thereof; (2) providing an extruder with an extrusion die; (3) extruding the material into a medical tubing; (4) providing a surface modifier solution; (5) preheating the surface modifier solution to a temperature within the range of 50-80° C.; and (6) applying the preheated solution onto the tubing at it exits the extrusion die when the tubing is in a molten state or a semi-molten state.

Abstract: The present invention provides a method for fabricating flexible medical tubings comprising the steps of providing a tubing of a polymer material, the tubing having a longitudinal axis and an initial diameter, orienting the tubing along the longitudinal axis of the tubing to reduce the diameter of the tubing to define a oriented diameter, and applying heat to the oriented tubing to heat set the tubing to maintain dimensional stability of the tubing over a temperature to which the tubing will normally be exposed.
