Abstract
A catheter comprising a first elongate flexible member having a cylindrical outer surface and having proximal and distal ends. A metallic band of radio opaque material is disposed on the outer surface of the elongate member in the vicinity of the distal end of the elongate member. A tubular member of a flexible material is carried by the distal end of the elongate member and encapsulates the metallic band to prevent its accidental dislodgment from the tip of the catheter.
