  • Patent number: 9125754
    Abstract: An artificial disc prosthesis is provided. The prosthesis of the present invention enables spinal segment alignment by having a variable height across its surface. The variable height is achieved by an asymmetric artificial nucleus or by at least one variable height end plate.
    Type: Grant

  • Patent number: 8231677
    Abstract: An artificial disc prosthesis is provided. The prosthesis enables spinal segment alignment by having a variable height across its surface. The variable height is achieved by an asymmetric artificial nucleus or by at least one variable height end plate. The prosthesis may have a central keel on one end plate and an offset pair of keels on a second end plate. The nucleus may engage a slot or trough in an inner surface of an end plate. The trough can be open on the posterior or anterior end to allow the nucleus to slide into the trough without undue distraction of adjacent vertebrae. The nucleus can be prevented from moving out of the trough by inserting a stop in the trough.

  • Patent number: 8092542
    Abstract: The invention relates to a surgical implant that provides an artificial diarthroidal-like joint, suitable for use in replacing any joint, but particularly suitable for use as an intervertebral disc endoprosthesis. The invention contains two rigid opposing shells, each having an outer surface adapted to engage the surfaces of the bones of a joint in such a way that the shells are immobilized by friction between their outer surfaces and the surfaces of the bone. These outer surfaces are sufficiently rough that large frictional forces strongly resist any slippage between the outer surface and the bone surfaces in the joint. They may be convex, and when inserted into a milled concavity, are immediately mechanically stable. Desirably, the outer surfaces of the shells are adapted to allow for bony ingrowth, which further stabilizes the shells in place.

  • Patent number: 7967862
    Abstract: A method for implanting an articulating intervertebral disc prosthesis into an intervertebral disc space comprises surgically accessing the intervertebral disc space through an opening on a first lateral side of the intervertebral disc space and inserting a first half of the articulating intervertebral disc prosthesis through the opening and into the intervertebral disc space. The method further comprises inserting a second half of the articulating intervertebral disc prosthesis through the opening on the first lateral side of the intervertebral disc space and positioning the first half of the articulating intervertebral disc prosthesis on a second lateral side of the intervertebral disc space. The method also comprises positioning the second half of the articulating intervertebral disc prosthesis on the first lateral side of the intervertebral disc space.

  • Patent number: 7641692
    Abstract: The invention relates to a surgical implant that provides an artificial diarthroidal-like D joint, suitable for use in replacing any joint, but particularly suitable for use as an intervertebral disc endoprosthesis. The invention contains two rigid opposing shells, each having an outer surface adapted to engage the surfaces of the bones of a joint in such a way that the shells are immobilized by friction between their outer surfaces and the surfaces of the bone. These outer surfaces are sufficiently rough, while the inner surfaces of the shells are relatively smooth. The central body has a shape that cooperates with the shape of the inner surface of the shell so as to provide a range of motion similar to that provided by a healthy joint.

  • Patent number: 7601174
    Abstract: An implantable endoprosthesis is adapted to articulate with one or more prosthesis surfaces, and is at least partially formed from a material having high wear resistance, which may be a polymeric material such as ultra-high molecular weight polyethylene (UHMWPE), polyetherether ketone (PEEK), and the like, or a metallic material, such as a cobalt-chrome alloy, or a ceramic material, such as alumina or zirconia. The body member of the endoprosthesis may be formed from a composite material, and includes at least a first component formed from a first material having increased wear resistance as compared to that of a second material forming a second component of the body member. The second material is generally more resilient as compared to the first material.
