  • Patent number: 9522028
    Abstract: Disclosed is a fixation device for sacroiliac joint stabilization. The fixation device includes an elongated body comprising a bone anchor at a distal end. An axially moveable proximal anchor is carried by the proximal end of the fixation device. In one embodiment, the device is inserted through the ilium of the pelvis and the bone anchor is rotated into position within the sacrum. The proximal anchor is distally advanced with respect to the bone anchor to provide compression across the sacroiliac joint.

  • Patent number: 9522070
    Abstract: An adjustable spinal fusion intervertebral implant including upper and lower body portions each having proximal and distal surfaces at proximal and distal ends thereof. The implant can include a proximal wedge member disposed at the proximal ends of the respective ones of the upper and lower body portions, and a distal wedge member disposed at the distal ends of the respective ones of the upper and lower body portions. First and second linkages can connect the upper and lower body portions. Rotation of an actuator shaft can cause the distal and proximal wedge members to be drawn together such that longitudinal movement of the distal wedge member against the distal surfaces and the longitudinal movement of the proximal wedge member against the proximal surfaces causes separation of the upper and lower body portions.

  • Patent number: 9492194
    Abstract: A dilation introducer for orthopedic surgery is provided for minimally invasive access for insertion of an intervertebral implant. The dilation introducer may be used to provide an access position through Kambin's triangle from a posterolateral approach. A first dilator tube with a first longitudinal axis is provided. A second dilator tube may be introduced over the first, advanced along a second longitudinal axis parallel to but offset from the first. A third dilator tube may be introduced over the second, advanced along a third longitudinal axis parallel to but offset from both the first and the second. An access cannula may be introduced over the third dilator tube. With the first, second, and third dilator tubes removed, surgical instruments may pass through the access cannula to operate on an intervertebral disc and/or insert an intervertebral implant.

  • Patent number: 9408648
    Abstract: Disclosed is a fracture fixation device, for reducing and compressing fractures in a bone. The fixation device includes an elongate body. An axially moveable proximal anchor is carried by the proximal end of the fixation device and comprises a tubular sleeve that includes a plurality of graduations positioned on an outer surface of the tubular sleeve. The device is rotated into position across the femoral neck and into the femoral head, and the proximal anchor is distally advanced to lock the device into place. In certain embodiments, the elongated body includes a distal anchor with a distal cutting tip.

  • Patent number: 9387313
    Abstract: Tissue dilation systems are disclosed. The present systems provide percutaneous access to one or more target structures located in a patient's body. The tissue dilation systems include two or more tissue dilation tubes telescopically arranged and moveable relative to each other. The tissue dilation tubes can be preassembled prior to use by utilizing a dilation tube retention assembly which can maintain the dilation tubes in a substantially fixed position and release the tubes therefrom in order to dilate a patient's tissue. Methods of producing the present systems and using the present systems in surgical procedures are also disclosed.

  • Patent number: 9101411
    Abstract: Fusion of cervical spinal vertebrae with one or more fixation devices can be accomplished with the described tools and methods. For example, a guidewire introducer can include a tubular introducer cannula and a handle. The handle can be angularly offset from the introducer cannula such that positioning of the introducer on the cervical spine does not interfere with a patient's head. A sheath assembly can include inner and outer sheath bodies and a handle. The handle is angularly offset from the sheath bodies such that the sheath assembly can be applied to the cervical spine without interference to the patient's head. The sheath body can be curved or straight. Various tools such as drills, tapping devices, compression tools, and pin release tools can be applied to the cervical spine through the sheath body to apply the fixation device. The tools can include elongate flexible shafts.

  • Patent number: 9028533
    Abstract: A method and apparatus of limiting at least one degree of movement between a superior vertebral body, an inferior vertebral body, and an intermediate vertebral body that is disposed between the superior and inferior vertebral bodies of a patient. The method can comprise: advancing a distal end of a stabilization device into a pedicle of the intermediate vertebral body; positioning a proximal portion of the stabilization device such that the proximal portion limits at least one degree of movement between the superior vertebral body and the intermediate vertebral body by contacting a surface of the superior vertebral body; and advancing a distal end of a fixation device into a facet of the intermediate vertebral body and into a facet or pedicle of the inferior vertebral body for stabilizing the intermediate vertebral body and the inferior vertebral body.
