An interbody spacer system for insertion between a first vertebra and a second vertebra according to the principles of the present disclosure includes and interbody spacer and a first curved blade. The interbody spacer includes an outer wall and a first surface for engaging an endplate of the first vertebra and a second surface for engaging an endplate of the second vertebra. A first entry aperture in the outer wall and a first exit aperture on the first surface communicate with a first curved path extending therebetween. The first curved blade enters the first entry aperture and exits through the first exit aperture to secure the spacer to the first vertebra.

Stand alone interbody fixation system

An intervertebral fixation device is disclosed, which includes a weight-bearing shell, a first anchor, a second anchor, and a key. The shell includes a first and second opposing sidewalls at a distance from one another, a keyway that extends along at least a portion of the distance, and a first axis of rotation and a different second axis of rotation that extend along at least a portion of the distance and are outside the keyway. The first anchor is rotatably coupled to the weight-bearing shell about the first axis of rotation, and the second anchor is rotatably coupled to the weight-bearing shell about the second axis of rotation. The key is insertable into the keyway such that the first anchor and the second anchor are securable in divergent orientations with respect to the weight-bearing shell.

Minimally invasive lateral intervertebral fixation system, device and method

Spinal disk including a shell, first endplate, second endplate and core. The shell includes sidewalls, back wall, front wall, top wall, and bottom wall defining a compartment. The first endplate includes a first base, first top and first attachment. The first base is retained in the compartment. The first top is disposed about a first opening in the top wall to form a top contact surface. The first attachment extends from the first top portion. The second endplate includes a second base, second top and second attachment. The second base is retained in the compartment. The second top is disposed about a second opening in the bottom wall to form a bottom contact surface. The second attachment extends from the second top portion. The core includes a material injectable into a constrained space in the compartment between the first base and the second base.

Implantable spinal disk

Spinal disk including a shell, first endplate, second endplate and core. The shell includes sidewalls, back wall, front wall, top wall and bottom wall defining a compartment. The first endplate includes a first base, first top and first attachment. The first base is retained in the compartment. The first top is disposed about a first opening in the top wall forming a top contact surface. The first attachment extends from the first top portion. The second endplate includes a second base, second top and second attachment. The second base is retained in the compartment. The second top is disposed about a second opening in the bottom wall forming a bottom contact surface. The second attachment extends from the second top portion. The core is disposed in the compartment between the first endplate and the second endplate.

An intervertebral fixation device and system are disclosed, including a weight-bearing shell, first anchor, second anchor, and key. The shell includes a first and second opposing sidewalls, a keyway that extends between and through the first and second sidewalls, and a first axis of rotation and a second axis of rotation that extend between the first and second sidewalls. The first anchor is rotatably coupled to the shell about a first axis of rotation and is disposed in a first orientation. The second anchor is rotatably coupled to the shell about a second axis of rotation and is disposed in a second orientation. The second orientation is divergent from the first orientation. The key is configured to be disposed in the keyway to support the first anchor in a third orientation and the second anchor in a fourth orientation. The third orientation is divergent from the fourth orientation.

Spinal disk including a shell, first endplate, second endplate and core. The shell includes sidewalls, back wall, front wall, top wall and bottom wall defining a compartment. The first endplate includes a first base, first top and first attachment. The first base is retained in the compartment. The first top is disposed in a first opening in the top wall forming a contact surface continuous with a surface of the top wall. The first attachment extends from the first top portion. The second endplate includes a second base, second top and second attachment. The second base is retained in the compartment. The second top is disposed in a second opening in the bottom wall forming a contact surface continuous with a surface of the bottom wall. The second attachment extends from the second top portion. The core is disposed in the compartment between the first endplate and the second endplate.

A system, device and method are disclosed for minimally invasive lateral intervertebral fixation. An intervertebral fixation device includes a weight-bearing shell configured to fit into a disk space between plural vertebrae, the weight-bearing shell including a keyway opening between and through plural sidewalls. A first plurality of anchors is rotatably disposed in a first orientation in relation to the weight-bearing shell. A second plurality of anchors is rotatably disposed in a second orientation in relation to the weight-bearing shell. A key is adapted to rotate the first plurality of anchors in divergent directions from the second plurality of anchors and to secure a first vertebra and a second vertebra, respectively. The key is further adapted to support the first plurality of anchors and the second plurality of anchors in divergent directions in relation to the weight-bearing shell, the first plurality of anchors and the second plurality of anchors secured to the first vertebra and the second vertebra.

Minimally invasive lateral intervertbral fixation system, device and method

An implantable spinal disk including an external shell, first endplate, second endplate and core component. The external shell includes sidewalls, a back wall, a front wall, a top surface and a bottom surface forming a compartment. The first endplate includes a first base, first top and first attachment devices. The first base is disposed in the compartment. The first top is disposed in a first opening in the top surface. The first attachment devices extend from within the first top portion. The second endplate includes a second base, second top and second attachment devices. The second base is disposed in the compartment. The second top is disposed in a second opening in the bottom surface. The second attachment devices extend from the second top. The core component is disposed in the compartment between the first endplate and the second endplate.
