  • Patent number: 11241262
    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: 11191570
    Abstract: A method of fabricating an “extension ready” spinal support system that enables the extension to be accomplished with minimal disturbance to an existing spinal support structure to which the extension system is coupled. In some embodiments, the existing spinal support rod and pedicle screws can remain intact while extension subassemblies are mounted directly to the existing base rod receptacles. The extension subassemblies include a skirt portion that surrounds and engages the existing base receptacle to prevent splaying of the base receptacle. Additional resistance to splaying may be provided by forming a canted thread arrangement between the skirt and the base receptacle. In some embodiments, the extension receptacle presents a low profile (i.e., shortened axial length from the base rod receptacle) is fabricated with a monoaxial rotation structure that rotates about but does not pitch relative to the extension axis and is shorter relative to polyaxial rotation structures.

  • Patent number: 11179146
    Abstract: A retractor for use in surgical operations comprises a pair of blade assemblies. In operation, the blade assemblies are initially in a closed position to assume a low profile, inserted into a relatively small incision, and stretched apart from each other, thereby stretching the skin about the incision to form an aperture longer than the incision. The retractor is adapted to rotate a first blade about a first axis and a second blade about a second axis. The retractor is adapted to move the pair of blade assemblies apart along a third axis. The retractor is adapted to pivot the first blade about a fourth axis and the second blade about a fifth axis. In some embodiments, a method of performing an operation, e.g. a spinal operation, on a patient using the disclosed retractor is provided.
