Abstract

La présente invention concerne un cathéter médical (10) présentant un long corps allongé (12) comprenant : une couche interne (20) ; une couche de renforcement (22) composée d'un fil (26) entourant l'extérieur de la couche interne (20) ; et une couche externe (24) recouvrant l'extérieur de la couche de renforcement (22). Dans une plage prédéfinie de la direction longitudinale du corps allongé (12), les éléments suivants sont prévus : une première région (30) au niveau de laquelle la surface périphérique du fil (26) est partiellement ou entièrement recouverte dans la direction périphérique par un matériau de recouvrement (28) séparé de la couche interne (20) et de la couche externe (24) ; et une seconde région (32) au niveau de laquelle le fil (26) n'est pas recouvert par le matériau de recouvrement (28) et est apparent.
