摘要: An elongate polymer member having molecular helical orientation formed by rotation immediately after passing through the extrusion head. The elongate polymer member is rotated downstream of the extrusion head in the molten state prior to solidification in order to impart the molecular helical orientation. Rotating the polymer member 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.

摘要: Various coupling agents are disclosed to form lap joints between metallic and polymeric surfaces within catheters and other medical devices. The coupling agents disclosed in the present invention can be applied directly to a metallic surface, or the coupling agents may be incorporated within a polymeric material. In certain circumstances, the mere application of the coupling agent between the two dissimilar materials provides sufficient adhesive strength to form a fatigue-free lap joint bond. Alternative methods utilize coupling agents as primers for later thermal bonding and laser welding procedures that form lap joint bonds.
