  • Patent number: 11931091
    Abstract: The present disclosure includes devices and methods of treating a herniated disc comprising treating an opening in a vertebral disc by applying plasma to the vertebral disc, wherein the vertebral disc comprises a nucleus portion and an outer annulus fibrosus portion, and wherein the plasma seals the opening in the vertebral disc. The devices and method comprises a plasma delivery device configured to be handheld and used percutaneously or in minimally invasive surgery. The vertebral disc, which comprises a nucleus pulposus and an outer annulus fibrosus, can be herniated with a rupture caused by a tear or opening in the annulus fibrosus, that can be repaired when the annulus fibrosus is sealed by the use of the plasma.

  • Patent number: 11918488
    Abstract: Embodiments of the present disclosure includes method and devices for minimally invasive spinal fusion surgery. A method for minimally invasive spinal fusion surgery can include accessing a spinal column through a working channel device, wherein the working channel has a proximal end and a distal end, advancing the working channel so that the distal end pierces an outer layer of a vertebral disc, inserting a disc extractor through the working channel device and into the vertebral disc to cut the vertebral disc into pieces, inserting a disc blade through the working channel device and into the vertebral disc to cut the vertebral disc into pieces, using a disc rake to remove the pieces of the vertebral disc, inserting a disc shaver to clean a number of surfaces of vertebra adjacent to the vertebral disc, and inserting and implanting a disc implant in a space from where the vertebral disc was removed.

  • Patent number: 11622864
    Abstract: An expandable intervertebral implant includes a superior plate having a proximal end, an opposing distal end, and a threaded first hole. An inferior plate has a proximal end, an opposing distal end, and a first bore, the inferior plate at least partially bounding an elongated channel that communicates with the first bore. A first lift screw includes a gear wheel rotatably received within the first bore of the inferior plate and a threaded stem projecting from the gear wheel and being threaded into the first hole of the superior plate. A drive screw is rotatably disposed within the channel of the inferior plate, the drive screw having a worm that engages with the gear wheel such that rotation of the drive screw facilitates rotation of the first lift screw which in turn facilitates movement of the superior plate relative to the inferior plate.

  • Patent number: 11432810
    Abstract: A retractor system may provide access to a surgical site along an access pathway surrounded by tissue. In some embodiments, the retractor system may include three arms and four retractor blades, each having a tissue engagement surface. The second arm may translate along a first retraction direction relative to the first arm. The first retractor blade may be securable to the first arm and the second retractor blade may be securable to the second arm. The third arm may have a connection feature that may be removably securable to a connection interface of the second arm. The third retractor blade may be securable to the third arm and the fourth retractor blade may be securable to a rack between the first and second arms. The third and fourth retractor blades may have cross-sectional shapes oriented generally parallel to the first retraction direction.
