Abstract

Stimulateur cardiaque comportant un générateur d'impulsions et une source d'électricité telle qu'une pile, et incorporé dans un boîtier de faibles dimensions. Il est caractérisé en ce qu'une électrode connectée opérationnellement au générateur d'impulsions présente une portion de forme hélicoïdale faisant saillie en dehors du boîtier et solidaire de ce dernier. Le boîtier a des dimensions suffisamment réduites pour permettre l'implantation du stimulateur au cours d'une thoracotomie limitée par rotation du boîtier, ceci afin d'insérer par rotation l'électrode dans le tissu cardiaque du patient, cest-à-dire dans le myocarde. Le boîtier peut être réalisé en un matériau électriquement conducteur isolé de l'électrode, et une portion de ce boîtier peut servir d'électrode de mise à la masse. Applications thérapeutiques au cas de déficience cardiaque.
