Abstract: An implant for insertion between vertebral members in which an inner member, intermediate member, and outer member are concentrically disposed. The inner and outer members may comprise end plates to contact the vertebral members. The outer member may include a tapered interior wall. A locking element is movably contained within an opening that extends through a sidewall of the intermediate member. The intermediate member is displaceable longitudinally in first and second directions relative to the outer member. Displacement of the intermediate member in the first direction tends to force the locking element laterally into contact with the inner and outer members. A biasing member may urge the intermediate member in the first direction. Displacement of the intermediate member in the second direction allows the locking element to be laterally displaced out of contact with the inner member.

Abstract: Devices to grasp a medical element that may include a first member, a second member that fits within the first member, and a locking element. The first and second members may move relative to one another to move the locking element between locked and unlocked positions. In an unlocked position, the device may move along the element. In the locked position, the device may lock to the element and motion is prevented. In one application, the device can be placed in the locked position to maintain a desired amount of tension on the element. Methods of grasping the medical element may include moving the first and second members relative to each other thereby moving the locking element to grasp and release the medical element.

Abstract: A connection assembly between a spinal implant rod and a vertebral anchor. The assembly has a longitudinal member, a housing, a rod interface washer, and a compression member. The longitudinal member has an aperture at one end and a wedge at the other. The housing has a passageway to accept the shank of a bone screw and a bore to accept the wedge. The bore is open to the passageway so that when the wedge is pulled from the bore it pushes against the shank of the bone screw, trapping the bone screw between the wedge and the sidewalls of the passageway. Threading a setscrew into the aperture presses a spinal rod against the washer, presses the washer against the housing, and pulls the wedge against the shank of the bone screw. Further tightening of the setscrew then locks the bone screw and rod together.

Abstract: Mechanisms for connecting an elongated member for orthopedic support or therapy to bone or other tissue are disclosed. Embodiments may include a receiver member with a channel for accommodating an elongated member such as a spinal rod and a channel for accommodating a bone-engaging member, a bone-engaging member that is insertable into the channel in the receiver member, and a lock member for locking the receiver member, bone-engaging member, and elongated member together. The channels may be variously oriented with respect to each other. Methods for using such embodiments are also disclosed.

Abstract: System and methods are provided that include a plate member engageable to the spinal column with an anchor assembly. The anchor assembly includes a coupling member having a post extending through at least one opening of the plate member and an anchor member pivotally captured in a receiver member of the coupling member below a lower surface of the plate member. A locking member secures the plate member to the coupling member.

Abstract: Systems and methods are provided for bending an elongate member used in a medical procedure. In one form, a system includes an insulated fabric that is used to grasp and bend a heated elongate member. The elongated member is heated to its glass transition temperature (Tg) using a heating element. The insulated fabric may be lined with a non-stick coating to prevent adhesion of the heated elongate member to the insulated fabric. In another form, a PEEK rod is heated using a sheath. The inner surface of the sheath is lined with Teflon to prevent adhesion as stated above. The sheath includes a plurality of semi-rigid coils to assist in bending the rod and to prevent the rod from being crushed during the bending process. The heating element may be included in the semi-rigid coils in this form.

Abstract: Embodiments of a spinal implant system include a fixation element, a connector body, and a compression member. The fixation element has a bone engaging portion, a pivoting portion, and a hinge portion. The hinge portion permits pivotal motion of the pivoting portion relative to the bone engaging portion. Additionally, the connector body defines a channel configured for receipt of an elongate member and defines an elongate slot configured for receipt of the pivoting portion of the fixation element. The pivoting portion is positionable in any one of a plurality of positions along the elongate slot. The compression member is adapted to engage the pivoting portion of the fixation element and press against the connector body to lock the pivoting portion at a desired angular position relative to the bone engaging portion and lock the connector body to the fixation element at the desired position along the elongate slot.

Abstract: A posterior fixation system includes a saddle member and an anchoring member. The anchoring member anchors the saddle member to bone. The saddle member includes a pair of upright portions that define a channel. The saddle member further has a hole therethrough bounded by an inner wall, and the hole forms a lower opening in the saddle member. The lower opening in the saddle member may contain angular cutouts placed symmetrically about the axis of the saddle to increase the allowable angulation of the bone screw in relationship to the axis of the saddle. The channel is adapted to receive an orthopedic rod, and the hole in the saddle member is adapted to receive the anchoring member. The saddle member and the anchoring member can be coupled so as to allow multi-axial movement of the members.

Abstract: A dynamic surgical table system includes any one or combination of a head support system, support systems for each arm, a torso support system, and a leg support system mounted to a frame system to support a patient during surgery. Any one or combination of the support systems is movable relative to the other and to the frame system to facilitate patient repositioning during surgery. Such repositioning may be desirable, for example, to create flexion, extension or rotation of the spine to facilitate access to and surgical treatment of one or more vertebral bodies, disc spaces between vertebral bodies, or other anatomical structures adjacent the spine of the patient. Furthermore, individual support members of any one of the support systems can articulate to conform to the patient anatomy and facilitate repositioning of the particular portion of the patient's body being support thereon while minimizing stress on the patient.

Abstract: Disclosed is a novel connection assembly for a spinal implant system having: a novel interface element having an internal stop that limits rotation of the spinal implant rod and associated members with regard to the spinal implant bolt and associated members allowing the implant system to initially assume a position that approximates its final adjusted position and allows the assembly's size to be reduced without sacrificing its mechanical strength; a compressible member located between the interface elements that ensures free rotation of the spinal implant rod and its associated members in relation to the spinal implant bolt and its associated members until a proper position has been obtained and allows an initially secured system to be repositioned without additionally separating the interface element's locking structures; and components provisionally secured to prevent disengagement during transportation and handling that can be engaged during installation utilizing minimal force with common hand tools.

Abstract: A connection assembly between a spinal implant rod and a vertebral anchor. The connection assembly includes a spindle and a housing. The spindle has an aperture for receiving a spinal implant rod in a spinal implant system. And structure for urging the rod within the aperture, such as a setscrew, is provided through a suitable threaded opening in the spindle so as to be extendable into the aperture. The housing has an aperture for receiving a shaft or shank of a vertebral anchor of a spinal implant system. The housing also has an aperture for receiving a generally cylindrical projection portion of the spindle. Structure for urging the shank of the vertebral anchor against the projection portion, such as a setscrew, is provided through a suitable threaded opening in the housing.
