Abstract

Ce tube est caractérisé en ce qu'il comprend une paroi 11 tubulaire extrudée de forme allongée, sensiblement homogène, et un cordon 12 extrudé, noyé dans cette paroi par co-extrusion et disposé en hélice le long de cette paroi, l'un de ces deux éléments étant opaque aux rayons X, tandis que l'autre (paroi ou toron) est translucide en lumière visible. Ce tube est utilisable, notamment en médecine, pour des sondes, cathéters, etc.
