A two-part joint replacement device for replacing damaged soft joint tissue, such as a meniscus or cartilage tissue. In one form, the device may include a free floating soft joint tissue replacement component comprising a first tissue-interface surface shaped to engage a first anatomical (bone and/or cartilage) structure of a joint having damaged soft tissue. The device may also include a free floating rigid base component comprising a second tissue-interface surface shaped to engage a second anatomical (bone and/or cartilage) structure of the joint. The free floating soft joint tissue replacement component may be shaped to slidably interface with the rigid base component. In another form, the free floating soft joint tissue replacement component and the rigid base component are fixed together.

A system and method for embedded electronics within a medical implant comprising: an implant body; a circuitry surface, containing at least one electronic component, wherein the circuitry surface is at least partially embedded within a defined cavity of the implant along at least one path; sheathing, comprising a protective structure, wherein the at least partially embedded portion of the circuitry surface is enclosed within the sheathing; electronic components connected to, or directly on, the circuitry surface, comprising a set of electrodes and an antenna; and wiring, connecting the circuitry surface and electronic components. The system and method may further include a casing, wherein the casing is a sealed structure directly connected to the implant body including a printed a circuit board (PCB) contained within the casing itself.

The invention relates to a modular anchoring adaptor that engages with existing features of commercially available ALIF cages to help eliminate migration and/or anterior expulsion cause by the instability of the spine, such as lordosis. Such modular adaptor will mate or engage with existing features to enhance anchoring within the vertebral disc space, which space is limited and a low-profile should be maintained.

Intervertebral endoprosthesis discs suitable for surgical implantation between two vertebrae having and methods thereof. The prosthetic disc may have an endoprosthesis body including an anterior region and a posterior region designed to be positioned between a first vertebra and a second vertebra with a first and second movable insert positioned rotatably in anterior cavities and is rotatable to adjust the fasteners.

A vertebral insert may include a first linkage, a second linkage, and a third linkage. The first, second, and third linkages may at least partially defining a cavity. The insert may be movable between a collapsed configuration and an expanded configuration, and the movement of the first and second linkages with respect to one another may be configured to reciprocally move the insert between the collapsed and expanded configurations.

An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

ALIF spine implants, ALIF installation instruments/tools, and ALIF procedures using the present ALIF implants and present ALIF installation instruments for an anterior lumbar interbody fusion (ALIF) surgical procedure are provided. The ALIF implants are characterized by an ALIF cage and anchoring members. The ALIF installation instruments are characterized by a shaft having an inserter on one end that receives and holds an ALIF cage and anchoring members. The installation instrument allows insertion of the ALIF cage into a vertebral space, the anchoring members to be received in the ALIF cage, and then into vertebral bone. The ALIF cage is preferably, but not necessarily, 3-D printed having a central cavity, an end configured to accept a plurality of anchoring members and direct a portion of the anchoring members up and out of the cavity, a cutout configured to receive an anchoring member retention component, and an anchoring member retention component.

Embodiments herein are generally directed to expandable spinal implants, systems, apparatuses, and components thereof that can be used in spinal fusion and/or stabilization procedures, as well as methods of installation. The expandable spinal implants may be configured for lateral insertion.

An expandable implant includes a top support assembly defining an upper surface configured to engage a first portion of bone, a first central aperture extending from the upper surface to an interior of the implant, and a first grid structure surrounding the first central aperture; a bottom support assembly defining a lower surface configured to engage a second portion of bone, a second central aperture extending from the lower surface to the interior, and a second grid structure surrounding the second central aperture; and a control assembly coupled to the top support assembly and the bottom support assembly and configured to control relative movement between the top support assembly and the bottom support assembly between a collapsed position and an expanded position.

A prosthesis for spinal surgery includes a spacer adapted to be secured into the bone and attached to one of a plurality of configuration plates. The configuration plates are interchangeable and each one is configured to utilize a different combination of bone screws, anchors or both. The prosthesis may further include a retaining mechanism to prevent bone screws and/or anchors from backing out.
