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

This disclosure relates to intervertebral disc prostheses which may have an upper plate, a lower plate, and a mobile core, with the upper surface of the core being in contact with at least a part of the lower surface of the upper plate. In some configurations, limit stops reduce friction while limiting or preventing the movements of the core relative to the lower plate, in translation and in rotation, respectively, along an axis substantially parallel to the lower plate and about an axis substantially perpendicular to the lower plate. Instrumentation for insertion of the prostheses into intervertebral spaces is also described.

Intervertebral disc prosthesis

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.

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

This equipment includes at least one U-shaped clip () whose lateral branches () have sections and widths such that they may be inserted in the vertebral bodies () of two vertebrae by impaction on the intermediate branch () of the clip (), so as to rest along the cortical bones of the vertebral bodies, and whose intermediate branch () is deformable in such a way as to allow a reduction of the distance between the lateral branches (); the intermediate branch, before implantation, has a length such that one of the lateral branches () may be positioned slightly above the cortical bone forming the plate of the subjacent vertebra while the other lateral branch () may be positioned slightly below the cortical bone forming the plate of the subjacent vertebra, and has, after deformation, a length such that the two lateral branches () may be brought closer to each other.

Vertebral osteosynthesis equipment

The disclosure relates to intervertebral disc prostheses, which may comprise at least three pieces including an upper plate, a lower plate, and a core mobile at least relative to the lower plate, the upper surface of the core being in contact with at least a part of the lower surface of the upper plate. Various embodiments have limit stops allowing friction to be limited, while limiting or preventing the movements of the core relative to the lower plate, in translation and in rotation, respectively, along an axis substantially parallel to the lower plate and about an axis substantially perpendicular to the lower plate, and have at least one hole disposed along the lower surface of the core facilitating sliding of the core relative to the upper surface of the lower plate with which it is in contact. Instruments for inserting intervertebral prostheses are also disclosed.
