Abstract

L'applicateur (24), combiné avec une canule (22) pouvant être fendue, permet de placer un cathéter (26) à travers une membrane du corps puis se sépare du cathéter (26) de façon à le laisser en place, l'applicateur et la canule étant jetables. Le cathéter est maintenu durant le placement. La canule est totalement contenue dans l'applicateur, sauf lorsque son extrémité distale est insérée dans la membrane du corps. La profondeur d'insertion est aisément contrôlée.
