  • Publication number: 20190343641
    Abstract: The present invention relates generally to implants and tools for the fixation or fusion of joints or bone segments. These tools include tissue dilators and protectors. Other tools include broaches used to shape bores in bone. The tools can also include a system for removing an implant from bone. Implants can include assemblies of one or more implant structures that make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. Implants for fusing both sacroiliac joints of a patient include a long implant that extends across both sacroiliac joints.

  • Publication number: 20130267989
    Abstract: The present invention relates generally to tissue dilators and protectors. More specifically, this application relates to tissue dilators and protectors used in medical procedures such as bone fixation or fusion. One embodiment of a soft tissue protector includes a port for coating an implant with a biologic aid. One embodiment of an expandable dilator includes a plurality of slidably connected longitudinal wall segments. One embodiment of a delivery sleeve includes a flexible tapered portion configured to expand.

  • Patent number: 6576016
    Abstract: Method and apparatus for promoting a spinal fusion between neighboring vertebrae. Apparatus may be located within the intervertebral disc space and preferably includes a pair of engaging plates for contacting the vertebrae. An alignment device may be used to alter the vertical distance between the engaging plates to customize the apparatus to fit a given patient. In one embodiment, the alignment device includes a pair of struts having a predetermined height and extending between the engaging plates from an anterior end to a posterior end of the apparatus. In another embodiment, the alignment device includes a rotatable connector and cam pins for adjusting the distance between the engaging plates. The alignment device is preferably adapted to vary the distance between the engaging plates such that the height of the apparatus proximate the anterior end is greater than that proximate the posterior end whereby the natural lordosis of the spine is maintained after the apparatus is installed.

  • Patent number: 6565566
    Abstract: A sacral screw assembly may provide a connection to a sacrum for a spinal fixation assembly. The sacral screw assembly may include a fixation component, connector, spinal rod, and a fastener. The connector and fixation component are configured to interconnect so that the connector inhibits translational and rotational motion of a spinal rod that is positioned within an opening of the connector. The connector may include a flared arm tip. The flared arm tip may fit within a groove of the fixation component to help position the connector within a cavity of the fixation component. The flared arm tip may also inhibit passage of the connector through the top of the cavity. The fixation component may have a threaded shank. The threaded shank may have a coarse pitch section located near a head of the fixation component, and a fine pitch section located near an end of the shank.
