An occluded perfusion catheter is provided that allows a controlled amount of a drug to be locally delivered to an injury site. An occlusion perfusion catheter 100 for introducing fluid into an isolated space, the space being spaced apart on the distal end of a catheter shaft 160 for isolating the space. The occlusion balloons 210, 250, the drug delivery skive port 440 provided on the outer wall of the catheter shaft located between the occlusion balloons, and the position away from the drug delivery skive port on the outer wall of the catheter shaft located between the occlusion balloons And a space occupying balloon 230 provided between the drug delivery skive port and the suction skive port, and the inflated space occupying balloon does not contact the wall forming the space. This allows fluid communication between the drug delivery skive port and the suction skive port. There is a configuration to be maintained. [Selection] Figure 2 |
