The present invention relates to ablation electrode assemblies. The present invention further relates to an insulated irrigated ablation electrode assembly (10). The insulated irrigated ablation electrode assembly (10) of the present invention includes a proximal member (18), a distal member (20) and an intermediate thermally insulating member (22). The proximal member (18) includes a body portion (24) defined by an outer surface (26), an inner cavity (28) defined within the outer body portion, and at least one passageway that extends from the inner cavity (28) to the outer surface (26) of the body portion (24). The distal member (20) of the electrode assembly (10) includes a distal end. Moreover, the intermediate member (22) of the electrode assembly (10) is disposed between the proximal member (18) and the distal member (20) thereby thermally insulating the proximal member (18) from the distal member (20).La présente invention concerne des ensembles formant électrode dablation. La présente invention concerne en outre un ensemble électrode dablation (10) irrigué et isolé. Lensemble électrode dablation (10) irrigué et isolé selon la présente invention comprend un élément proximal (18), un élément distal (20) et un élément intermédiaire thermiquement isolant (22). Lélément proximal (18) comprend un corps (24) défini par une surface extérieure (26), une cavité interne (28) définie à lintérieur du corps extérieur, et au moins un passage qui sétend depuis la cavité interne (28) vers la surface extérieure (26) du corps (24). Lélément distal (20) de lensemble électrode (10) comprend une extrémité distale. De plus, lélément intermédiaire (22) de lensemble électrode (10) est placé entre lélément proximal (18) et lélément distal (20), isolant ainsi thermiquement lélément proximal (18) de lélément distal (20).
