Abstract:
1. A device for protecting a patient's sublaminar thecal sac and pari-laminar soft tissue structures while performing procedures on a spinal lamina of a patient, the spinal lamina having a longitudinal axis, said device being configured to be placed parallel to the longitudinal axis of the lamina and proximate to the lamina, and said device comprising: a sub-laminar wall and a supra-laminar wall, that converge at an inner surface at both a proximal end and a distal end of a tip, wherein the distal end of the device includes curved or angled leading outer surfaces configured to be convergent thus resulting in a tapering of the tip of the device, the converging sub-laminar and supra-laminar walls allowing the patient's lamina to be separated from the overlaying and underlying tissues; and a cannulate cylinder at least partially disposed above the supra-laminar and sub-laminar walls allowing access to the lamina with at least one of surgical tools, placement of devices, medications, or other therapeutic agents.
