  • Patent number: 7862582
    Abstract: Various exemplary methods and devices are provided for tensioning suture. The methods and devices are particularly useful in surgical suturing applications in which it is desirable to maintain tension on suture being delivered, yet to allow the tension to be released as desired without retracting the suture. Thus, when tension is released, a length of suture extended from the device can remain extended without any tension being applied thereto. Tension is only applied to any additional length of suture that is extended from the device. The tension applied to the suture is proportional to the length of the suture extended from the device until the tension is released and reset.

    Abstract: Disclosed are devices and systems for spinal fixation and dynamic stabilization. Elongated members may be positioned lateral to spinous processes and coupled to two or more vertebrae. Interspinous members may be positioned between adjacent spinous processes and coupled to the elongated members. One embodiment of an interspinous member comprises a body and two lateral portions. The lateral portions may couple to the elongated members to position the interspinous members. An interspinous member and the positioning of the interspinous member may allow selected movement between the adjacent spinous processes.

  • Publication number: 20090088769
    Abstract: Alignment apparatuses, methods, and systems for positioning guidewire insertion devices into a patient's vertebrae. The alignment apparatus can facilitate insertion of a guidewire insertion device through a stab incision made in a patient's skin and into target vertebrae of the patient in a spinal fixation procedure. The apparatus may comprise a housing having at least one opening. The housing can be positionable against the patient's skin proximate to the target vertebrae. The opening may be configured to receive the guidewire insertion device so that it directs the advancement of the guidewire insertion device through the opening and the stab incision.

  • Publication number: 20090088803
    Abstract: The present application is directed to devices and methods for correcting a spinal deformity. The devices may include a member attached to one or more vertebral members of a deformed spine. The member may be constructed of a flexible material with elastic properties. The member is attached to the vertebral members in a stressed orientation. Due to the elastic properties of the material, the member exerts a corrective force on the vertebral members. In some embodiments, multiple members are attached to the vertebral members to apply the corrective force.

  • Publication number: 20090082811
    Abstract: Methods for delivering a spinal fixation element to a surgical site are provided herein. More specifically, the method includes delivering a plurality of percutaneous access devices to a corresponding number of spinal locations, inserting a spinal fixation element through tissue, and manipulating the element through opposed sidewall openings formed in each access device. In an exemplary embodiment, the method can be optimized for position of large-scale fixation elements (e.g., greater than about 95 mm in length). In addition, a manipulation instrument configured to position such spinal fixation elements is also provided herein.

  • Publication number: 20090082812
    Abstract: Provisional locking pedicle screw systems and associated methods for surgery are provided. A bone screw assembly may be provided that includes a bone screw, an anchor bracket, and a provisional locking member. The provisional locking member may exert a frictional force against the bone screw that semi-rigidly fixes the anchor bracket and the bone screw in place relative to each other. More rigid securement (e.g., non-provisional locking) of the relative positions of the bone screw and the anchor bracket may be achieved by securing a securement member (e.g., set screw) within the anchor bracket. Also provided are a multiple-component set screw and an anchor bracket configured to form a press-fit connection with the bone screw. In various embodiments, the systems and methods described herein may be used to fuse together, mechanically immobilize, and/or adjust the alignment of adjacent vertebrae of the spine.

  • Publication number: 20090076549
    Abstract: A system is provided for use in orthopedic surgery, for example to connect a spinal rod with a vertebral screw or hook. The system generally includes a receiver member for receiving an elongated member, a bone implant member, such as a bone screw, and a locking washer to assist in locking the receiver member at a desired angular position relative to the bone implant member. The receiver member and the washer may be positioned on opposite sides of the bone implant member. Additionally, the receiver member may define an aperture to receive a closure member to lock an elongated member in a passage in the receiver member.
