摘要：
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).Linvention porte sur un cathéter pour la perfusion locale de médicaments qui comprend, dans un premier mode de réalisation, un cathéter (10) à trois lumières (11, 12 et 13) comportant un ballonnet docclusion (20) dans sa partie proximale et un ballonnet de perfusion (30) dans sa partie distale, des ouvertures (15) étant ménagées dans la surface du cathéter (10) entre le ballonnet docclusion (20) et le ballonnet de perfusion (30) afin de permettre la perfusion distale dune solution saline, le ballonnet de perfusion (30) créant une chambre (50) entre la surface de sa partie médiale (33) et la paroi de lartère (100). Dans un deuxième mode de réalisation, le cathéter de perfusion locale de médicament comprend un cathéter (10) à une lumière (13) équipé dun ball
