  • Expandable device
    Patent number: 11918481
    Abstract: The present invention provides expandable devices and insertion tools for deploying the expandable devices. The expandable devices are capable of increasing in height and width when expanded from a closed configuration to an open configuration to occupy a larger volume and to present a larger surface area. The expandable devices are lockable and are capable of rigidly occupying a space after expansion. In some embodiments, the expandable devices are useful as interbody devices for spinal fusions.

  • Decorticating Screw
    Publication number: 20220304672
    Abstract: The present invention provides decorticating screws and insertion tools for implanting the decorticating screws. The screws anchor into a first and a second bone to fuse the two bones together. The screws include a rotatable bladed section to decorticate a joint space between the first and second bone. The screws also optionally include a cap to secure the screws in the bone and apply compression to the joint to be fused. In some embodiments, the decorticating screws are useful for sacroiliac (SI) joint fusion.

  • Minimally Invasive Subdural Evacuating System
    Publication number: 20210338277
    Abstract: The present invention provides minimally invasive subdural evacuating systems and methods of use thereof. The subdural evacuating systems include a cutting component and a rod component, wherein the rod component provides an external physical indicator that the surface of the dura mater has been reached, permitting the cutting component to accurately pierce the dura mater with minimal to no risk of damaging any adjacent anatomy.
