Abstract

Une électrode présentant un mécanisme de fixation capable de se déployer et de se rétracter comporte à son extrémité terminale une broche terminale rotative mettant en rotation le mécanisme de fixation à son extrémité distale. Lorsque la broche terminale est en rotation, la mécanisme de fixation est déployé ou replié depuis l'extrémité distale de l'électrode. Un collet fileté permet au mécanisme de fixation de se déployer ou de se rétracter doucement de l'électrode, et permet un rapport de nombre de tour 1:1 entre la broche terminale et le mécanisme de fixation. Une bague radioscopique disposée au niveau de l'extrémité distale de l'électrode fournit des informations pendant le processus d'implantation.
