Title (EN) METHODS AND APPARATUS FOR PERFUSION OF ISOLATED TISSUE STRUCTURE
(FR) PROCEDES ET APPAREIL DE PERFUSION DANS UNE STRUCTURE TISSULAIRE ISOLEE
Abstract:
(EN) Organs and other tissue structures (O) are isolated which are perfused with a therapeutic agent. Isolation is effected by endovascularly positioning catheters (10, 16) having occlusion balloons (12, 14) within the arteries or other blood vessels which supply blood to the organ. Similarly, blood flow from the organ back to the patient's circulatory system is blocked by endovascularly positioning one or more catheters carrying occlusion members within the veins or other blood vessels leading from the organ. The therapeutic agent may then be perfused through the organ in either an antegrade or retrograde fashion using the endovascularly positioned catheters while maintaining isolation.
(FR) On isole des organes et d'autres structures tissulaires (O) et on y envoie par perfusion un agent thérapeutique. On procède à l'isolement en positionnant de manière endovasculaire, des cathéters (10, 16) dotés de ballonnets d'occlusion (12, 14) à l'intérieur des artèr es ou des vaisseaux sanguins qui alimentent l'organe en sang. De même, on bloque la circulation du sang de l'organe à l'appareil circulatoire du patient, en positionnant de manière endovasculaire un ou plusieurs cathéters portant des éléments d'occlusion, dans les veines ou d'autres vaisseaux sanguins partant de l'organe. On peut ensuite envoyer l'agent thérapeutique par perfusion dans l'organe, de manière antérograde ou rétrograde, au moyen des cathéters positionnés de manière endovasculaire, tout en maintenant l'isolement.
