Abstract
A catheter having an elongated shaft with a tubular member which forms at least a portion of the shaft and which is formed of a biaxially oriented thermoplastic polymeric material, and a method of forming the catheter shaft by radially and longitudinally expanding the tubular member to biaxially orient the polymeric material. A catheter of the invention has an improved combination of low bending stiffness, high rupture pressure, and high tensile strength, for improved catheter performance.
