The present invention relates to an implant, an instrument for implanting the implant, and a method for manufacturing the implant which includes an elongated body between a free end and a head along a longitudinal axis on the one hand and turns of at least one threading on at least one portion of said body in proximity to the free end, along the longitudinal axis on the other hand, characterized in that the body includes a longitudinal internal conduit in at least one portion to along the longitudinal axis, obtained by at least one first central machining operation parallel to the longitudinal axis and at least one second machining operation in a so-called transverse plane, not parallel to the longitudinal axis and crossing the wall of the body as far as the longitudinal internal conduit by making windows communicating between said longitudinal internal conduit and the outside of the body.

Bone implants

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

An expandable intervertebral implant comprises an expandable cage comprising a central frame, a superior endplate, an inferior endplate, an anterior adjustment mechanism and a posterior adjustment mechanism. The central frame including an anterior (distal) threaded bore and a posterior (proximal) bore. The superior (upper) end plate movably coupled along a posterior portion of the central frame. The inferior (lower) end plate movably coupled along the posterior portion of the central frame opposite the superior end plate. The anterior adjustment mechanism including an anterior wedge coupled to an anterior screw movable within the anterior threaded bore. The posterior adjustment mechanism including a posterior wedge coupled to a posterior screw movable within the posterior bore.

Expandable intervertebral implant with independent adjustments

A device or system to adapt navigation trackers from various manufacturers to a variety of instruments to be navigated during a surgical procedure is disclosed. An adapter for coupling a navigation tracking array to an instrument including a drive shaft and a tracking device holder. The drive shaft can include a handle interface, an instrument connection, and an intermediate section including a circular locking groove extends proximally from a positioning flange. The tracking device holder can be configured to secure a navigation tracking array to the drive shaft and include an elongated body and a locking button. The elongated body can include an inner bore extending along a longitudinal length of the elongated body and adapted to receive the intermediate section of the drive shaft. The locking button can retain the tracking device holder along the drive shaft while allowing for rotation about the longitudinal axis.

Universal navigation instrument adapter

The present invention relates to an implant, to an instrument for implantation of the latter and to a method for manufacturing this implant which includes an elongated body () between a free end and a head () along a longitudinal axis on the one hand and turns () of at least one threading on at least one portion of said body () in proximity to the free end, along the longitudinal axis on the other hand, characterized in that the body () includes a longitudinal internal conduit () in at least one portion to along the longitudinal axis, obtained by at least one first central machining operation parallel to the longitudinal axis and at least one second machining operation in a so-called transverse plane, not parallel to the longitudinal axis and crossing the wall of the body () as far as the longitudinal internal conduit () by making windows () communicating between said longitudinal internal conduit () and the outside of the body ().

This disclosure provides vertebral implants, fastening devices for vertebral implants, and implant instrumentation, and various combinations thereof. In some embodiments, the implant comprises a peripheral wall extending according to a vertical axis between upper and lower surfaces of the implant, with each such surface configured to be placed in contact with a vertebral structure, respectively, at the top and the bottom of the vertebral segment replaced by the implant. Some embodiments comprise fastening means, deployment of which anchors the implant in the lower and upper vertebral structures. Some fastening means may be deployed by sliding parallel to the vertical axis of the implant, and may comprise a plate with at least one part remaining in contact with the peripheral wall of the implant when deployed and a pointed end projecting from one of the upper and lower surfaces of the implant to enter a vertebral structures on completion of deployment.

Vertebral implant, vertebral fastening device of the implant and implant instrumentation

Anchoring devices, anchoring systems for intervertebral implants, intervertebral implants, and instruments and methods for implanting implants are disclosed. In preferred configurations, these various objects share the feature of comprising or cooperating with an anchoring device having a body comprising at least one curved plate elongated along a longitudinal axis, designed to be inserted through a passage crossing at least a part of implant, in order to penetrate into at least one vertebral endplate and attach implant onto this vertebral endplate by means of at least one stop retaining the implant, characterized in that the body comprises at least one longitudinal rib on at least a part of at least one of its faces, said rib being designed to cooperate with a groove made in passage of implant. In some preferred configurations, anchoring device comprises withdrawal stops or latches, and/or means for withdrawing the anchor from an inserted position.

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.

The present invention relates to an implant, to an instrument for implantation of the latter and to a method for manufacturing this implant which includes an elongated body () between a free end and a head () along a longitudinal axis on the one hand and turns () of at least one threading on at least one portion of said body () in proximity to the free end, along the longitudinal axis on the other hand, characterized in that the body () includes a longitudinal internal conduit () in at least one portion along the longitudinal axis, obtained by at least one first central machining operation parallel to the longitudinal axis and at least one second machining operation in a so-called transverse plane, not parallel to the longitudinal axis and crossing the wall of the body () as far as the longitudinal internal conduit () by making windows () communicating between said longitudinal internal conduit () and the outside of the body ().
