Abstract

L'invention porte sur un cathéter médical comprenant: une extrémité proximale présentant une ouverture pour des liquides contenant un produit thérapeutique, une extrémité distale présentant au moins une ouverture, et une partie poreuse recouvrant ladite ouverture. Dans l'une des exécutions, le cathéter médical comprend: une extrémité proximale présentant une ouverture pour des liquides contenant un produit thérapeutique, au moins deux extrémités distales, l'extrémité proximale étant raccordée aux extrémités distales par un connecteur, et les extrémités distales présentant chacune au moins une ouverture, un diffuseur couvrant les ouvertures de chacune des extrémités distales, et deux étrangleurs séparés placés en aval du connecteur et en amont de chacune des extrémités distales et égalisant sensiblement les flux traversant lesdites extrémités distales. On peut également placer un étrangleur supplémentaire en amont du connecteur. Dans une autre exécution, un combiné diffuseur étrangleur recouvre les ouvertures de chacune des extrémités distales.
