  • Retro guidewire reamer
    Patent number: 10758252
    Abstract: A retro guidewire reamer includes a cutting member, and a mechanism for moving the cutting member from a closed position to a deployed position in a single manual motion. Once a desired size of a bone tunnel is established, a surgeon uses the reamer to create a primary bone tunnel over a guidewire from the outside in. The surgeon retracts the guidewire, and activates the mechanism to deploy the cutting member within the bone joint to conform to the size of a tendon graft. The surgeon uses the deployed cutting member to create a counter bore through the bone in a retrograde manner. Once the counter bore is drilled, the surgeon activates the mechanism to close the cutting member, allowing the reamer to be withdrawn through the primary tunnel. The retro guidewire reamer can be used to provide more accurate bone tunnel placement during ligament reconstruction surgery.

  • Endoscopic assistance devices and methods of use
    Patent number: 10758117
    Abstract: Insufflation is currently considered to be a necessary part of an endoscopic procedure. However, it introduces risks and costs that would be beneficial to eliminate. The endoscopic assistance devices and methods disclosed herein facilitate the performance of endoscopic procedures without insufflation. The devices attach directly or indirectly to the distal end portion of the endoscope. One or more resilient, curved bars extend from the attachment point around an internal void space to form a resilient, curved cage that spreads tissue gently during the advance of the endoscope. The resilient, curved bars define the windows of the cage that enable the visualization of the internal anatomy via a lens on the distal face of the endoscope and the passage of treatment devices from the operative channel of the endoscope.
