INFUSION CATHETER DEVICE FOR TREATING AT LEAST PARTIAL OR TOTAL OBSTRUCTION IN A DUCT, SUCH AS BODY CONDUIT

摘要

The invention relates to an infusion catheter device. This catheter device 10 comprises an elongated substantially tubular shape defining a longitudinal axis, a distal end (D) and a proximal end (P), configured to be introduced into a conduit (50) having an inner wall (54) and an outer wall (56) comprising at least one obstruction (60) or partial or total occlusion to be treated, said device comprising at its distal end (D) one or more orifices (16, 18, 20, 22) for infusing a liquid infusion (LI), and upstream of the infusion port (s), proximal (P) side of the infusion catheter (10), at least one provisional closure shutter member (70) configured to treat said obstruction ( 60) or occlusion and infusing the infusion liquid (LI) downstream of the shutter member (70) and in the closed position. This device is particularly suitable for cardiac surgery and interventional cardiology.
