  • Patent number: 9775653
    Abstract: A method for attaching a laminar plate to a vertebra during spinal surgery, especially minimally invasive spinal surgery, to reconstruct the lamina of the vertebra after it has been removed during the surgery and prevent bone re-growth material from entering the spinal canal. The laminar plate can be coupled to, or proximate to, and between a facet and the spinous process by screwing the plate to the bone.

  • Patent number: 9642650
    Abstract: A method for placement of a pedicle screw and rod system that has particular application for spinal fusion surgery. The system includes pedicle screws having ball-shaped heads that are threaded through pedicles of adjacent vertebra into the vertebral body. The system also includes two cannulated posts having a head portion with a planar portion and an opening for accepting the head of the pedicle screw in a secure and multi-axial engagement. The system further includes a tube portion that is coupled to the head portion and extends above the patient's skin. The system also includes a lordotic slotted rod that is slid down the tube portions to be positioned on top of the head portions of the posts so that the planar portions are locked within the slot. Bolts are then slid down the tube portions and are threaded to a threaded portion on the planar portion.

  • Publication number: 20140276591
    Abstract: A regeneration device and method for sealing annular tears between the nucleus pulposus and the annulus fibrosus of an intervertebral disc. The regeneration device includes a trocar having a sharp tip at a distal end, an inner cavity, and a handle portion attached to a proximal end of the trocar. The device further includes a plunger coupled to a catheter that extends through the inner cavity. The regeneration method includes inserting the trocar into an intervertebral disc via Kambin's triangle, and once the trocar reaches the nucleus pulposus, the catheter is extended alongside the annulus fibrosus wall to surround the nucleus pulposus. A syringe is mounted to the plunger and injects a biochemical, biological and/or synthetic material through multiple ports in the catheter to form a collagen barrier that prevents the nucleus pulposus from protruding through the annulus fibrosus.

  • Patent number: 8795296
    Abstract: A needle delivery device that has particular application for providing needles for minimally invasive spinal surgical procedures. The device includes an elongated pincher having opposing rails that is slidable within a channel defined in an extended base portion. Widened end portions of the rails hold the needle and push it out of an end of the device where it is released. The pincher is then retracted to a location where the end portions can pick up a next needle to be delivered.

  • Patent number: 8690920
    Abstract: An interspinous process spacer insertion device that positions an interspinous process spacer between the spinous process of adjacent vertebrae in a minimally invasive percutaneous surgical procedure. The device includes a trocar rod that extends through a cannulated sleeve. The spacer is attached to the end of the cannulated sleeve, where a trocar tip of the trocar rod extends through the spacer. The trocar rod is moved through the cannulated sleeve and an incision in the patient, and is positioned between the spinous process of the vertebra to align the device. The cannulated sleeve is then moved down the trocar rod so that the spacer slides between the spinous process, and the trocar rod is then withdrawn from the patient. The spacer is then rotated so that it locks behind the spinous process, and the cannulated sleeve is detached from the spacer and removed from the patient.

  • Patent number: 8454583
    Abstract: A robotic surgical device positioning system that allows a surgeon to accurately and remotely position a surgical instrument relative to a patient and to provide fluoroscopic images of the instrument without exposing the surgeon to radiation. The system includes a vertical post that is slidebly coupled to an operating table, a clamp mounted to the vertical post and spaced from the table, and a translational arm mounted to the clamp. The system further includes an instrument positioning assembly mounted to the translational arm opposite to the clamp that includes a plurality of sliding elements that are slidebly mounted to the assembly to provide rotational, anterior-posterior and medial-lateral positioning of the surgical instrument. A control unit is mechanically coupled to the instrument positioning assembly at a remote location by flexible cables for controlling the position of the sliding elements.

  • Patent number: 8192443
    Abstract: A pedicle access device that has particular application for positioning a pedicle screw during a minimally invasive spinal fusion surgical procedure. The pedicle access device includes a positioning needle having a hollow tube and a specially designed tip that conforms with a facet complex of a vertebra proximate a pedicle. A targeting needle having a pointed end is inserted through the hollow tube of the positioning needle, and is secured thereto so the tip of the targeting needle extends out of the end of the positioning needle. The tip of the targeting needle allows the positioning needle to be accurately positioned on the pedicle, and the specially configured tip of the positioning needle allows it to be secured thereto without slipping.
