  • Publication number: 20230270428
    Abstract: A surgical wire is part of a system that includes a retractor blade defining one or more paths for the surgical wire to follow. The paths can be one or more openings, cannulations, paths, tubes, other structures, or combinations thereof. The surgical wire can be routed through the front, back, and/or middle of the retractor blade and into a vertebral body. The surgical wire can be routed through a shim in communication with the retractor blade and into a vertebral body Systems and methods are used to insert surgical wires into bone. Systems and methods are used for removing surgical wires from bone. Systems include those for gripping and pulling or pushing surgical wires. Systems include those that interact with a retractor (e.g., an arm, body, or blade thereof) to facilitate removal of the surgical wire.

  • Patent number: 11672637
    Abstract: A method for making a polymer with a porous layer from a solid piece of polymer is disclosed. In various embodiments, the method includes heating a surface of a solid piece of polymer to a processing temperature and holding the processing temperature while displacing a porogen layer through the surface of the polymer to create a matrix layer of the solid polymer body comprising the polymer and the porogen layer. In at least one embodiment, the method also includes removing at least a portion of the layer of porogen from the matrix layer to create a porous layer of the solid piece of polymer.

  • Patent number: 8480559
    Abstract: A urethral support system is described, including an introducer device and tissue implant. The introducer device may include a needle with multiple curves, some of the curves having multiple radii. A sheath assembly may be utilized to assist the passing of the tissue implant through a patient's tissue. The sheath assembly may include connectors configured to connect the sheath assembly to an end of the needle and a tab configured to detachably couple sheath sides over the tissue implant.
