ABSTRACT:
The present invention provides a polymeric treatment for curved regions in shaft assemblies that increases curve retention without affecting the flexibility within these regions. More specifically, the present invention modifies the underlying crystalline morphology of a polymer in order to decrease crystal fracturing. In particular, the present invention treats polymeric materials suitable for catheter construction with a nucleating agent.
