  • Publication number: 20170181737
    Abstract: A suture grasping and passing device having a handle with an elongate tubular needle defining a lumen therein and extending from the distal end of the handle and having a pointed forward distal tip for puncturing soft tissue. A lateral radially open suture capture notch is provided in the tubular needle adjacent the pointed distal tip and defines a mouth open to the needle lumen. The notch mouth is contoured to receive a suture therein transversely across the mouth and an elongate gate member is slidably received for axial movement within the lumen whereby the gate member may be advanced in a forward direction to entirely close off an outer radial apex portion of the suture capture mouth to capture a suture under the gate member within the mouth of the notch.

  • Publication number: 20150238181
    Abstract: A method and apparatus for placing a suture (22) transosseously through first (15) and second (21) transverse intersecting bone tunnels wherein a suture retriever spike (12) having a window (20) therethrough is inserted in one of the tunnels (15) and the window (20) is aligned with the bore of the other tunnel (21). Suture (22) is passed through this second or other tunnel (21) and on through the spike window (20) and there deposited. The suture retriever spike (12) is then removed from its tunnel (15) with the suture (22) passed through the window (20) of the spike (12), thereby transosseously retrieving the suture (22).
