ABSTRACT:
A catheter assembly includes a tubing portion and a needle portion, at least one of which is a thermoplastic liquid crystalline polymer. The tubing and needle may be integral or unitary. The invention includes a method to make the assembly in which a melt of the liquid crystalline polymer is shear thinned by passing through an orifice such as an extrusion die to make tubing. The shear thinned melt may be directed into a mold having a point to make a liquid crystalline needle.
