A multi-lumen catheter (10) having a reinforcing member (42) wrapped around at least one of the lumens (40) in a helical manner. An inflation lumen (43) is positioned outside the reinforcing member (42) for inflating a balloon (11) carried by the catheter (10). A two-lumen extrusion (339A) is bonded to the reinforced lumen (337A) to form the multi-lumen catheter. The multi-lumen catheter is particularly useful as an aortic occlusion catheter.

Cette invention se rapporte à un cathéter à passages multiples (10) comprenant un élément de renforcement (42) enroulé autour d'au moins l'un des passages (40) de façon hélicoïdale. Un passage de gonflage (43) est placé à l'extérieur de l'élément de renforcement (42) de façon à pouvoir gonfler un ballonnet (11) porté par le cathéter (10). Une pièce extrudée à deux passages (339A) est collée au passage renforcé (337A), afin de former le cathéter à passages multiples. Ce cathéter à passages multiples est particulièrement utile comme cathéter d'occlusion aortique.
