Abstract
L'invention concerne un kit de dilatateur comprenant : un cathéter ayant une lumière ; et un dilatateur, le dilatateur étant logé dans la lumière du cathéter dans un état assemblé. Le cathéter a une section de mise en prise côté pointe et une section de mise en prise côté base qui viennent respectivement en prise avec le dilatateur dans l'état assemblé. Le dilatateur a une section en prise côté pointe qui vient en prise avec la section de mise en prise côté pointe du cathéter et une section en prise côté base qui vient en prise avec la section de mise en prise côté base du cathéter dans l'état assemblé. Dans un état séparé dans lequel le cathéter et le dilatateur sont séparés l'un de l'autre, la longueur entre la section en prise côté pointe et la section en prise côté base du dilatateur est supérieure à la longueur entre la section de mise en prise côté pointe et la section de mise en prise côté base du cathéter.
