Abstract:
A catheter comprises a tubular body portion (11) including an elongate portion (13) made of a transparent material, and at least one substantially linear contrast-radiography portion (14a, 14b) made of an X-ray opaque material and extending in the longitudinal direction of the elongate portion. The body portion (11) is hollow to allow passage of a liquid therethrough. A majority of the transparent material is composed of an aromatic polyurethane, while the material forming the at least one contrast-radiography portion (14a, 14b) is a mixture composed at least mainly of the X-ray opaque material and an aliphatic polyurethane.
