  • Publication number: 20170143331
    Abstract: An apparatus includes a handle, a cartridge configured to removably couple to the handle, an actuator movably coupled to the handle, and a lock operably coupled to the actuator. A first needle assembly and a second needle assembly of the cartridge are operably coupled to a first coupling portion and a second coupling portion, respectively, of the actuator when the cartridge is coupled to the handle. The first coupling portion is configured to transition the first needle assembly from a first configuration to a second configuration such that a first capture portion engages a first needle. The second coupling portion is configured to transition the second needle assembly from a first configuration to a second configuration such that a second capture portion engages the second needle. The lock is configured to selectively limit movement of the first coupling portion and the second coupling portion.

  • Publication number: 20160338745
    Abstract: Minimally invasive methods and devices for introducing a spinal fixation element into a surgical site in a patient's spinal column are provided. In general, the method involves advancing a spinal fixation element in a first, lengthwise orientation along a pathway extending from a minimally invasive percutaneous incision to a spinal anchor site. As the spinal fixation element approaches the spinal anchor site, the fixation element can be manipulated to extend in a second orientation, which is preferably substantially transverse to the first orientation, to position the fixation element in relation to one or more spinal anchors.

  • Publication number: 20160045233
    Abstract: Minimally invasive methods and devices are provided for positioning a spinal fixation element in relation to adjacent spinal anchors. In an exemplary embodiment, the device is a percutaneous access device that can be coupled to a spinal anchor, and the method includes the step of positioning a spinal fixation element through at least one sidewall opening of at least two percutaneous access devices such that the spinal fixation element extends in a lengthwise orientation that is substantially transverse to the longitudinal axis of each percutaneous access device. The spinal fixation element can then be advanced in the lengthwise orientation to seat the spinal fixation element in or adjacent to the receiver heads of at least two adjacent spinal anchors. A fastening element or other closure mechanism can then be applied to each spinal anchor to engage the spinal fixation element within the receiver heads of the adjacent anchors.

  • Patent number: 8512343
    Abstract: Methods and instruments are provided for connecting a rod extending along a patient's spinal column to a misaligned vertebra. The method comprises implanting a bone anchor in the misaligned vertebra, attaching an approximating device to the implanted bone anchor and rod, approximating the vertebra toward the rod using the approximating device, and connecting the rod to the bone anchor on the approximated vertebra. In certain embodiments the approximating device may include a winch mechanism. In other embodiments the approximating device is a cannula used in conjunction with a guide system.

  • Patent number: 8157847
    Abstract: The present invention expands a spinal canal by drilling a cylindrical passage in each pedicle of a vertebra, making a circumferential pedicle cut (osteotomy) through each pedicle from within the passage, separating each pedicle cut by inserting an implant into the passage which distracts the pedicle cut to expand the spinal canal, and securing each pedicle cut, allowing the vertebra to heal with the spinal canal expanded. The implant includes an outer sleeve, an inner bolt, and expandable flanges. The outer sleeve includes an upper portion and a lower portion, with the expandable flanges connected to the lower portion and housed within the upper portion. Rotation of the inner bolt causes the upper and lower portions of the outer sleeve to separate, causing the pedicle cut to widen and the expandable flanges to radially extend into and stabilize the widened pedicle cut to effectuate expansion of the spinal canal.
