Abstract

L'invention concerne un cathéter équipé d'un élément tubulaire (4); d'un ressort à lames (30) installé sur la partie interne de l'élément tubulaire (4) de telle sorte qu'au moins une partie des bords latéraux (30e, 30f) courant le long de l'axe de l'élément tubulaire (4) soient incorporés dans l'élément tubulaire (4); et plusieurs tubes (41-46) formant chacun plusieurs passages (31, 36) équipant chacun une première région (20A) sur une surface principale (30a) du ressort à lames (30) et une seconde région (20B) sur l'autre surface principale (30b) du ressort à lames (30) dans la partie interne de l'élément tubulaire (4) et comprenant des passages (31, 32) pour permettre la traversée de câbles d'actionnement. En outre, dans la première région (20A) et dans la seconde région (20B), certains tubes (43-46) sont disposés de manière à être en contact avec les surfaces principales (30a, 30b) du ressort à lames.
