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.
L'invention porte sur un cathéter comprenant un corps tubulaire (11) constitué d'une partie allongée (13) conçue dans un matériau transparent, et au moins une partie de radiographie de contraste sensiblement linéaire (14a, 14b) conçue dans un matériau opaque aux rayons X et s'étendant dans le sens longitudinal de la partie allongée (13). Le corps (11) est creux de façon à permettre le passage d'un liquide. Le matériau transparent est principalement composé d'un polyuréthane aromatique, alors que le matériau constituant la partie de radiographie de contraste (14a, 14b) est un mélange constitué d'un matériau opaque aux rayons X et d'un polyuréthane aliphatique.
