The present invention relates to a tissue ablation device assembly which is adapted to form a conduction block along a length of tissue between two predetermined locations along the left atrial wall. The assembly comprises an ablation element on an elongated ablation member which is coupled to each of two delivery members, the delivery members having first and second anchors, respectively, that are adapted to anchor at the two predetermined locations, such that the delivery members are adapted to controllably position and secure the ablation element along the length of tissue between the predetermined locations. A linear lesion in the tissue between the predetermined locations is then formed by actuation of the ablation element. The invention further provides that the ablation member may slideably engage one or two delivery members such that an adjustable length of the ablation element along the ablation member may be extended externally from the engaged delivery member and along a length of tissue.
La présente invention concerne un ensemble dispositif d'ablation tissulaire conçu pour la réalisation d'un bloc de conduction sur une longueur de tissus entre deux points définis le long de la paroi de l'oreillette gauche. L'ensemble comporte un ablateur situé sur un organe d'ablation qui est couplé à chacun de deux organes de présentation. Ces organes de présentations comportent chacun deux ancrages conçus pour s'ancrer aux deux points définis. En outre, les organes de présentation sont conçus pour positionner et maintenir avec toute la maîtrise voulue l'ablateur sur la longueur du tissu entre les points définis. L'invention prévoit également qu'un coulissement permet à l'organe d'ablation de venir toucher un ou deux organes de présentation faisant qu'une longueur réglable de l'ablateur situé le long de l'organe d'ablation puisse sortir télescopiquement de l'organe de présentation touché, le long d'une longueur de tissu.
