  • Publication number: 20240008998
    Abstract: An expandable spinal implant includes a distal projection extending from only one side of the implant, ending in an anterior tip, the anterior portion and anterior tip defining an elongated distal end hook, which is wider than the proximal end. The distal end hook rotates around the spinal cord, aligning the implant with a desired pathway, then inserts into place in the disc space between the vertebrae. The elongated widened distal end hook provides a TLIF approach, distributes loads, provides anterior rim engagement, and creates lordosis.

  • Patent number: 11471298
    Abstract: A spinal interbody fusion device for use in a plurality of surgical approaches includes a cage, a top end, a bottom end, and at least a first side representing the width of the cage and at least a second side representing a length of the cage. The cage includes fixation holes and inserter holes, with each fixation hole being configured for accepting a screw or anchor and each inserter hole being accessible for one or more surgical approaches for performing a spinal fusion. Also included are methods for selecting a size of an intervertebral implant and methods of surgically approaching a spine of a patient for spinal surgical procedures.

  • Patent number: 10610244
    Abstract: Systems and methods for joint preparation and fusion are disclosed. The system includes a cutting device having a handle, and rigid blade member. The blade member may include cutting edges on first and second sides, and may be curved in one or more planes. The blade member may be deployed to project outside of an outer tube, and the cutting device may be rotated to create a circular cavity. In a method of use, a cannula provides access to a procedure site such as a joint. A pathway to the joint is created, and the cutting device is inserted and deployed to undercut a cavity in the joint. A fusion device may be implanted across the joint to provide compression and fuse the joint. The system may also include instrumentation for creating access to a joint, bone graft insertion and implant insertion.

  • Publication number: 20110054408
    Abstract: A covering for delivering a substance or material to a surgical site is provided. The covering, with substance provided therein, may be referred to as a delivery system. Generally, the covering may be a single or multi-compartment structure capable of at least partially retaining a substance provided therein until the covering is placed at a surgical site. Upon placement, the covering may facilitate transfer of the substance or surrounding materials. For example, the substance may be released (actively or passively) to the surgical site. The covering may participate in, control, or otherwise adjust the release of the substance. In various embodiments, the covering is suitable for a variety of procedure specific uses. Implantation tools may be provided for placing the covering at a surgical site. Kits may be provided including variously sized or shaped coverings and one or more tools for use in placing the covering.

  • Publication number: 20100082072
    Abstract: Bone anchors and related methods for their use are described. The inventive anchor is suitable for placement in bone and for use in orthopedic surgery and dentistry. The bone anchor can be made from a bone/polymer or bone substitute/polymer composite, and can provide a firm and secure base for attaching a fastening device. The bone anchor can be used in various orthopedic and dental procedures including spinal surgery, where normal, cancellous, cortical, diseased or osteoporotic bone is present. The bone anchor can be resorbed and/or replaced with native bone tissue over a period of time. In certain embodiments, the bone anchor is made malleable or flowable and formed in situ or in vivo.
