A catheter (10) for treatment of a segment of a vessel carrying a body fluid is provided with two balloons (26, 28) carried axially spaced away from each other at the distal end section (14) of the catheter (10) for isolating the segment to be treated. In the catheter (10) at least one lumen (15, 30) for supplying a pressurizing medium to the balloons (26, 28) a further lumen (17, 36) leading to at least one port (38) in the catheter wall between the two balloons (26, 28) for delivering a therapeutic agent and a lumen (40) for receiving a guide wire are provided. The lumen (40) for receiving a guide wire is configured only in the end section (14) of the catheter (10) and extends between a port (42) incorporated in the catheter wall on the proximal side of said proximal balloon (26) and a port (44) located at the distal end of the end section (14).
L'invention porte sur un cathéter (10) de traitement d'un segment d'un vaisseau transportant un liquide corporel. Le cathéter (10) comporte, à son extrémité distale (14), deux ballonnets (26, 28) placés à distance l'un de l'autre de façon axiale afin d'isoler le segment à traiter. Il (10) inclut au moins une lumière (15, 30) pour fournir un milieu de pression aux ballonnets (26, 28), une autre lumière (17, 36) menant à au moins un orifice dans la paroi du cathéter, entre les deux ballonnets (26, 28), pour libérer un agent thérapeutique et une lumière (40) permettant de recevoir un fil guide. Cette dernière lumière (40) est prévue seulement à l'extrémité (14) du cathéter (10) et se prolonge entre un orifice (42) incorporé dans la paroi du cathéter du côté proximal du ballonnet proximal (26) et un orifice (44) situé au bout distal de l'extrémité (14).
