ABSTRACT:
A catheter and method for manufacturing catheters. The method includes the steps of manufacturing a tubular member sized and dimension for use as a catheter and irradiating the tubular member to impart a desired stiffness to the tubular member. A single coat catheter is constructed from a polymer tubular member irradiated to cross-link polymer molecules within the polymer tubular member, wherein cross-linking the polymer molecules alters properties of the polymer molecules to create a polymer tubular member having improved stiffness characteristics.
