The present invention relates to a catheter device (10) suitable for cardiac surgery and interventional procedures, the catheter device comprising an inner wall (54) and an outer wall (54) comprising at least one partial or total occlusion (60) or occlusion treated. Designed to be inserted into a passageway ( 50 ) having a ( 56 ), it has an elongate, substantially tubular shape defining a longitudinal axis, a distal end (D) and a proximal end (P). The device comprises one or more infusion ports 16 , 18 , 20 , 22 for injecting an infusion fluid LI at its distal end D, and an infusion catheter 10 upstream of the one or more infusion ports. At least one for a temporary seal designed to inject an injection liquid LI downstream from the sealing element 70 and treat the occlusion 60 or occlusion when it is in the sealing position on the proximal side P of a sealing element 70 . |
