Abstract

An expansible intervertebral implant is disclosed, various embodiments of which comprise an elongated body along a longitudinal axis comprised between a proximal end and a distal end, a flexible arm mounted in the vicinity of the distal end of the longitudinal body and movable between: a folded-back position with the arm substantially parallel to the axis, and a deployed position with the arm not parallel to the axis and away from the body to expand said implant along an axis, by assuming the general shape of a circular arc, a means for deployment of said flexible arm for deploying the latter from the folded-back position to the deployed position, by the sliding of a proximal portion of said flexible arm with respect to the body inducing an increase in the space occupied by the implant, greater than the space of the implant in the folded-back position.
