Abstract (en)
[origin: WO2009076732A1] A local drug infusion catheter described herein comprises in the first embodiment a three-lumen (11, 12, and 13) catheter (10) that has an occlusion balloon (20) in the proximal portion, an infusion balloon (30) in the distal portion, and openings (15) on the surface of the catheter (10) disposed between the occlusion balloon (20) and the infusion balloon (30) for the distal infusion of saline solution; the said infusion balloon (30) creates a chamber (50) between the surface of its medial portion (33) and the wall of the artery (100). In the second embodiment, the local drug infusion catheter comprises a one-lumen (13) catheter (10) fitted with an infusion balloon (30) that creates a chamber (50) between the surface of its medial portion (33) and the wall of the artery (100), said chamber (50) being sealed in the distal and proximal portions by the protrusions (32) disposed on the ends of the infusion balloon (30). In the third embodiment, the three-lumen (16, 17, and 18) catheter (10) has one occlusion balloon (60) in the proximal portion, one occlusion balloon (70) in the distal portion, and openings (19) disposed on the surface of the catheter (10) between the proximal (60) and the distal occlusion balloon (70).
