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 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.

Embodiments of instrumentation and methods are provided for the insertion of intervertebral disc prosthesis. The instrumentation of the embodiments comprises a guide comprising at least two lateral faces, at least one upper plate, at least one lower plate, at least one retainer, a cage defining an insertion axis for the prosthesis, and an angle adjuster adapted to adjust an angle formed by the insertion axis and an antero-posterior sagittal axis; and at least one separator sized to maintain a gap between the upper vertebra and the lower vertebra. Methods for implanting a prosthesis using the disclosed instrumentation comprise implanting a pin in the median sagittal axis of a vertebrae; measuring the dimensions of the intervertebral space; choosing the prosthesis; choosing the guide; adjusting the angle adjuster; positioning the guide adjacent to the intervertebral space; inserting the prosthesis into the guide; and inserting the prosthesis into the intervertebral space.

Instrumentation and methods for inserting an intervertebral disc prosthesis

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

Anchor removal instruments and methods for using the instruments are provided. In some embodiments, an intervertebral implant anchor extractor tool comprises a support, a support retainer configured to hold the support fixed with respect to the implant, an extractor having an anchor retainer, and an extractor guide. An embodiment of a method of using this implant anchor extractor tool comprises the steps of obtaining access to an anchor, grasping the anchor, and applying a withdrawal force on the anchor while applying a countervailing force against the implant or a vertebral structure.

Instruments and methods for removing fixation devices from intervertebral implants

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 (L), 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.

The present invention relates to an interspinous implant (), intended to be implanted between two adjacent dorsal spines (EI,ES), each including an upper edge (E), a lower edge (E) and two opposed lateral faces (E, E), wherein the implant () includes at least one body () with dimensions arranged so as to maintain or restore a distance between the adjacent edges (E, E) of the two spinous processes (EI, ES) and including at least two wings () extending so that at least a part of each wing () lies along at least a part of one lateral face (E, E) of one of the two spinous processes (EI, ES) and, additionally, at least one retainer (, L,) for the implant, designed to retain the body () of the implant between the two spinous processes and to be inserted from the same lateral face as the body ().
