  • Publication number: 20150230848
    Abstract: Described herein are bone implant having bifurcated struts for distracting and supporting bone, as well as systems and methods for treating bone using them. These self-expanding implants for repairing bone may include two or more bifurcated struts that extend from a central body or shaft in the deployed configuration. The stabilization device may be attached to an inserter. An inserter may be used to hold the stabilization device in a collapsed delivery configuration so that it can be inserted into bone.

  • Publication number: 20150196341
    Abstract: Described herein are devices, systems and method for assuring that connection regions (e.g., threaded regions) of stabilization devices are clear of bone filling materials such as bone cements. A stabilization device may be referred to as a bone stabilization device or an anchor, and may be a self-expanding device configured for insertion into bone. One exemplary clearing device is configured as a plunger-type device for clearing the connector region by scraping and/or rubbing the surface of the connector region. A clearing device may include a handle, a rod and a connector end that is configured to mate with the connector of a stabilization device. The connector end may include one or more scraping surfaces (e.g., edges) and may include a vacuum port for removing material such as scraped bone cement.

  • Publication number: 20100168748
    Abstract: Described herein are bone morcelizers for forming cavities in bone, particularly cancellous bone. In general, these devices include an outer cannulated member coupled to a proximal handle. An inner member may be extended and rotated relative to the outer member in a controlled manner, by operating one or more controls on the handle. The inner member may assume a curved shape relative to the outer member when it is extended.

  • Publication number: 20090292323
    Abstract: Described herein are stabilization devices, systems and methods to aid in posterior lumbar interbody fusion (PLIF) surgeries. The stabilization devices (“devices”) described herein are typically self-expanding devices that may be implanted into an intervertebral disc and packed with a bone graft or biologic or synthetic material to promote anchoring of the stabilization device and fusion of the vertebrae adjacent to the intervertebral disc.

  • Publication number: 20090012564
    Abstract: Described herein are devices and systems for transdiscal fusion of vertebrae and methods for fusing adjacent vertebra. A system may include a device with two anchorable members connectable by an intervening connector forming a continuous passageway therethrough. An anchorable member may have a constrained non-anchoring configuration and a released anchoring configuration. The anchoring configuration typically includes a radially-expanded structure such as a plurality of struts. After positioning the anchorable members into two adjacent vertebral bodies, the anchorable members may be released from their constrained configuration so that they radially self-expand, anchoring the device across the fracture. A flowable bone-filling material may be conveyed into the passageway of the device after implantation, stabilizing it further in the vertebral implantation site.

  • Publication number: 20090005821
    Abstract: Described herein are devices, systems, and methods for treating bone. Self-expanding stabilization devices for repairing bone may include one or more bone screw attachment regions for attaching a bone screw after or before inserting the device into a subject. The stabilization device may be attached using an inserter. These stabilization devices may be used with bone screws having multiple parts or components. Thus, the stabilization devices described herein may be used to help secure one or more bone screws (in particular pedicle screws) in a subject.

  • Publication number: 20090005782
    Abstract: The invention relates to a system for stabilizing a bone fracture and methods for applying the system. The system includes a device with two anchorable members with an intervening connector and a passageway through the device. The anchorable members have a constrained non-anchoring configuration and a released anchoring configuration. The anchoring configuration includes a radially-expanded structure such as a plurality of struts. After implantation across a fracture site, the anchorable members are released from their linearly constrained configuration, and structural features radially self-expand, anchoring the device across the fracture. A flowable bone-filling material may be conveyed into the passageway of the device after implantation. The composition fills the space within the expanded structures of the anchorable members and flows into space surround the device, stabilizing it further in the implantation site.

  • Publication number: 20080294204
    Abstract: The soft tissue anchor devices, systems and methods described herein may aid in the attachment of ligaments, muscles, tendons, and other soft tissues to bone. These soft tissue anchor devices typically include a self-expanding bone anchor region including an elongate shaft that may be positioned within bone and expanded to anchor to the bone, and one or more soft tissue attachment regions adapted to attach soft tissue thereto.

  • Publication number: 20080281364
    Abstract: Described herein are devices, systems, and methods for treating bone, particularly for restoring bone dimension in compression fractures. Self-expanding stabilization devices for repairing bone may include two or more continuous curvature of bending struts that extend from a central shaft in the deployed configuration. The stabilization device may be attached to an inserter. An inserter may be used to hold the stabilization device in a collapsed delivery configuration so that it can be inserted into bone. In use, the stabilization device may be part of a system or kit for installing the device into a bone region and allowing it to expand to correct a bone fracture.
