Title
(EN) CATHETER FOR TARGET SPECIFIC DRUG DELIVERY
(FR) CATHETER D'ADMINISTRATION DE MEDICAMENTS SPECIFIQUES DE CIBLES
Abstract
(EN) A medical catheter (22) comprising a proximal end (24) having an opening for fluid containing a therapeutic drug, a distal end (26), the distal end defining at least one opening, and a porous portion covering the opening defined by the distal end. In one embodiment, the medical catheter comprises a proximal end having an opening for fluid containing a therapeutic drug, at least two distal ends (26, 26'), the proximal end connected to the two distal ends with a connector (50), the distal ends each defining at least one opening, a diffuser covering the opening of each distal end, and a separate restrictor downstream of the connector and upstream of each distal end to provide substantially equal flow through each distal end. An additional restrictor can also be placed upstream of the connector. In another embodiment, a combination diffuser and restrictor covers the opening of each distal end.
(FR) 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.
