Various embodiments of an intervertebral implant comprise a body extending longitudinally along a primary axis, a baseplate, a plurality of elongated arms having a vertebral support surface, the arms being articulated such that the implant has a folded-back position in which the arms are close to each other, and a deployed position in which the arms are moved away from each other, and expansion means between the folded-back and deployed positions, comprising at least two branches pivotably mounted relative to each other and attached to the elongated arms by guide means such that translation of the expansion means parallel to the primary axis causes pivoting of the branches and moves the arms away from each other.

Expansible intervertebral implant

Various embodiments of intervertebral implants, anchoring devices for intervertebral implants, and implantation instrumentation are provided, along with various embodiments of methods for using one or more of the devices. Some embodiments of an anchoring device have a body comprising at least one curve and a rigid plate elongated along a longitudinal axis so that its front end enters at least one vertebra while its rear end remains in the passage of an implant. In some embodiments, the plate comprises at least one longitudinal slot separating at least one posterior portion of the plate into two branches, with at least one branch comprising at least one withdrawal stop configured to retain the device in the implant.

Anchoring device and system for an intervertebral implant, intervertebral implant and implantation instrument

Various embodiments comprise an expansible intervertebral implant intended to be implanted in a space between two adjacent vertebrae to at least partly supplant an intervertebral disc, said implant being able to expand along three substantially mutually orthogonal axes so as to comply with the lordosis of the patient while still having increased stability and reliability.

Expansible intersomatic cage

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.

A vertebral support device () is disclosed, which in various embodiments comprises at least two osseous anchoring implants (), each designed to be anchored to a vertebra, and at least one linking element () fixed to the osseous anchoring implants () by fasteners () that maintain a fixed angle between the longitudinal axis (L) of the linking element () passing through rigid elements () of the linking element () and the insertion axis (DV) of the implants (). The linking element () includes at least one elastic dampening element () that that allows the implant-bearing vertebrae some freedom of movement. The dampening element () accommodates the stresses imposed on the linking element () during movement of the vertebrae and tends to return the support device () to its normal configuration.

Vertebral support device

The present invention relates to various embodiments of anchoring devices for intervertebral implants, intervertebral implant and implantation of instrumentation, sharing the characteristic to cooperate with the anchoring device () comprising a body comprising at least one curve, rigid plate () elongated along a longitudinal axis (L) so that its front end enters at least one vertebra while its rear end remains in the passage () of the implant () by pressing said implant () against said vertebra with at least one retaining stop (), the device () being characterized in that the plate () comprises at least one longitudinal slot () separating at least one posterior portion of the plate () into two branches () which at least one comprises at least one withdrawal stop () configured to retain the device () in the implant ().

Anchoring devices for rachidian implants, implants, surgical instruments, and surgical systems and methods are disclosed. In some embodiments, an anchor comprises a stiff plate with a longitudinal axis, configured for penetration of its anterior end into a vertebral surface while its posterior end remains engaged with the implant. An implant may include a locking mechanism for the anchor. An anchor may include an abutment configured to abut a complementary abutment of an implant. In some configurations, inserting an anchor in a passage of an implant may displace a locking mechanism, which may resile and lock the anchor in the implant with complementary abutments of the anchor and implant abutting.

Anchoring device for a spinal implant, spinal implant and implantation instrumentation

An osseous anchorage implant comprising an attachment structure adapted to receive and be attached to at least one bar is disclosed. The implant is made up of an osseous anchor and an attachment head bearing the attachment means. The attachment head is suitably traversed by a channel that is adapted to receive the bar. The attachment head comprises a clamp that is adapted to clamp the bar against an inside support wall of the channel. The implant is further characterized by the attachment means and the support wall enabling the rotation of the bar about a first axis that is not parallel to the longitudinal axis of the bar. The clamp comprises a moving clamping face, that is adapted to contact the bar, and that is borne by a support head. The bar is enabled to be introduced into the channel from a side of the channel.
