An implantable defibrillation electrode including a conductive distal end portion and a non-conductive proximal end portion is provided with at least a major portion of the length of the distal end portion havinq a pre-configured shape and being resiliently deformable into a generally straight condition. The distal end portion includes distal and proximal ends and at least one of those ends is hollow and has hook structure shiftably supported therein for movement longitudinally thereof from a retracted position at least substantially contained within the hollow end and an extended position at least substantially fully outwardly projected from the hollow end. Spring structure is provided for yieldingly biasing the hook structure from the extended position toward the retracted position and axial thrust developing structure is slidingly telescoped through the proximal end portion and operatively associated with the hook structure for exerting an axial thrust thereon from the terminal end of the proximal end portion in order to effect shifting of the hook structure from the retracted position to the extended position.

Électrode de défibrillateur interne comportant une partie distale conductrice, une partie proximale non conductrice, et dont la presque totalité de la partie distale présente une configuration en forme de spirale se prêtant à la déformation dans une configuration essentiellement rectiligne. La partie distale comporte une extrémité distale et une extrémité proximale, et au moins une de ces deux extrémités est creuse et loge une structure formant un crochet qui, pouvant être déplacé dans l'axe longitudinal, passe d'une position repliée à l'intérieur de l'extrémité creuse à une position dépliée à l'extérieur de celle-ci. Un mécanisme à ressort télescopique produit la poussée ou la traction nécessaire pour déplier la structure ou pour replier celle-ci sur elle-même.
