Abstract

La présente invention décrit un dispositif d'électrodes endocavitaire à passage unique adapté à l'implantation dans une seule ou plusieurs cavités du coeur, et constitué d'une première électrode d'extrémité distale et d'une deuxième électrode. La première et la seconde électrode sont attachées passivement ou activement à la paroi du coeur. Le dispositif d'électrodes contient aussi une partie incurvée pour faciliter le positionnement de la deuxième électrode. Comme alternative, la partie principale dudit dispositif contient un évidement dans lequel un corps d'électrode auriculaire et un élément de fixation active attaché à une extrémité peuvent se déplacer d'une position en retrait à une position de fixation à la paroi du coeur. L'élément de fixation active peut aussi être déplacé par rotation de la broche terminale. Le dispositif d'électrodes peut aussi inclure de nombreuses branches, chacune portant une électrode; il est relié à un générateur d'impulsion pour la production d'impulsions aux nombreux sites internes du coeur. Un assemblage de mise en mouvement pour l'avancement d'une hélice placée à l'intérieur des branches est constitué d'une bague filetée extérieurement qui s'enclenche avec un corps fileté intérieurement ou avec un logement fileté intérieurement. Le dispositif comprend de plus une extrémité hélicoidale à impédance élevée.
