Abstract

La présente invention concerne un cathéter à double lumen. Suivant l'invention, un cathéter interne 1 passe coaxialement dans un cathéter externe 2 en formant un canal annulaire 3 permettant le prélèvement et le renvoi de sang. Le cathéter externe 2 se termine à un écartement donné du débouché du cathéter interne 1 et sa zone d'extrémité 7 à diamètre rétréci vient s'appliquer sur le cathéter interne 1 en fermant le canal annulaire 3. Dans la paroi d'enveloppe du cathéter externe 2 sont prévus des orifices 8. Le cathéter interne 1 et le canal annulaire 3 sont reliés à des tuyaux souples 11, 14 par l'intermédiaire d'éléments de raccordement 9, 12. L'invention est utilisée en hémodialyse.
