  • Patent number: 10231842
    Abstract: Disclosed herein is an intervertebral tensional artificial disc replacement, insertable between adjacent vertebrae, which includes an inferior plate engaging with a lower vertebra and providing elastic force to an upper vertebra, and a superior plate seated on an upper portion of the inferior plate to engage with the upper vertebra, the superior plate being rotatable right and left within a certain angular range depending on rotation of the upper vertebra. Since the adjacent vertebrae are supported by elastic force, it is possible to prevent abrasion due to frequent friction between upper and lower bodies of the artificial disc replacement. In addition, the intervertebral artificial disc replacement can engage well with a spine and move well by locating the central axis of motion of the intervertebral artificial disc replacement at a rearward position, similar to the central axis of the body's spinal motion.

  • Patent number: 9962269
    Abstract: In some aspects, the present invention is a medical implant with an independent endplate structure that can stimulate bone or tissue growth in or around the implant. When used as a scaffold for bone growth, the inventive structure can increase the strength of new bone growth. The independent endplate structures generally include implants with endplates positioned on opposite sides of the implant and capable of movement independent of one another. In most examples, the endplates have a higher elastic modulus than that of the bulk of the implant to allow the use of an implant with a low elastic modulus, without risk of damage from the patient's bone. A method of designing independent endplate implants is also disclosed, including ranges of elastic moduli for the endplates and bulk of the implant for given implant parameters. Implants with elastic moduli within the ranges disclosed herein can optimize the loading of new bone growth to provide increased bone strength.

  • Patent number: 9393129
    Abstract: An interbody fusion device having an accordion-like structure, wherein the device in inserted into the disc space in its collapsed configuration and then expanded into its expanded configuration by compressing the accordion-like portion of the device. In some embodiments, a pre-formed tube with an accordion-like structure over a portion of its length is inserted in a relaxed (collapsed) configuration, giving the tube a minimum possible diameter. This tube has a cable running through it that is fixed to a distal end portion of the tube and extends past the proximal end portion of the tube to the outside of the patient. Once the tube is positioned on the rim of the endplate, the proximal end of the cable is pulled, thereby tensioning the cable and causing the accordion portion of the tube to become shorter in length but larger in diameter.

  • Patent number: 8808380
    Abstract: A method and apparatus for an osteotomy fixation or arthrodesis cage allows the adjustment of the relative position of two bone segments while supporting the joining of those bone segments into one structure through the implant and methods described herein. The implant's embodiments fixate to the adjacent bones while inter-positioning its body between the bone segments. This inter-positioning allows anatomical adjustments in the distance between and angle of the bone segments. The adjustment is further enhanced by the use of shape memory materials that when activated through the application of heat energy, transition from a second shape to a first shape while changing the distance between the bones or their relative angle. This method and apparatus can be used on any adjacent bone or bone segments including but not limited to the vertebrae of the spine or long bone such as the tibia or metatarsal.

  • Patent number: 8696753
    Abstract: An implant strip is disclosed. In some cases, the prosthesis can take the form of an implant strip that may be implanted through the use of a surgical procedure that minimizes incision sizes and may be considered less invasive than typical spinal implant procedures. The implant strip includes provisions for implantation, including teeth, spacing provisions, and various shapes.

  • Patent number: 8628576
    Abstract: Systems for interbody fusion of adjacent bone portions may include an expanding implant and related instruments. An expanding implant may be formed as a linkage which is movable between a compact configuration and an expanded configuration. A shaft of the implant may increase and decrease in length to move between the compact and expanded configurations, and an implant width perpendicular to the length may be increased in the expanded configuration. The implant width may increase more in a first direction than a second direction opposite the first direction. An inserter instrument may releasably grasp the spacer and transform the implant between the compact and expanded configurations.

  • Patent number: 8613758
    Abstract: An insert for establishing a desired spacing between a pair of succeeding vertebrae and having a body including an extending end for supporting a location associated with a first selected lumbar vertebrae. An opposite extending end supports a spaced apart and opposing location associated with a second successively positioned lumbar vertebrae. Upon pre-positioning the body in an open space established between the vertebrae, an actuating input causes the first extending end to displace outwardly relative to the second end and into contacting support with the vertebrae.
