Abstract:
An implantable prosthesis is described having a pair of opposed shells and a central body disposed between the opposed shells wherein the central body and the shells cooperate to limit the motion of the central body with respect to the shells. An assembly for preparing a disc space for the implantation of a prosthesis is further described having a plurality of instruments cooperating to guide a tool associated with the assembly.

Abstract:
An artificial spinal joint for creating at least a portion of a coupling between a superior vertebra and an inferior vertebra comprises a first joint half comprising a first intervertebral articulating assembly, a first rostral connection assembly, and a first caudal connection assembly. The joint further comprises a second joint half comprising a second intervertebral articulating assembly, a second rostral connection assembly, and a second caudal connection assembly. The joint further comprises a constraint component extending between the first rostral connection assembly and the first caudal connection assembly.
Surgical Tool And Method With An Actuation Mechanism For Controlling Reciprocation And Locking Of An Anti-Rotation Member Relative To An Engagement Member For Facilitating Positioning Of An Intervertebral Device

International Classification:

US Classification:
606 86A, 606 99
Abstract:
A surgical tool and method are provided for positioning an intervertebral device between vertebral members. The tool includes an elongate shaft, an anti-rotation sleeve, and an actuation mechanism. The shaft has proximal and distal ends, with the distal end of the shaft including an engagement member for releasably engaging an intervertebral device. The sleeve includes proximal and distal ends, and is movably mounted to the shaft for reciprocating relative thereto between retracted and extended positions. The distal end of the sleeve includes an anti-rotation member. The actuation mechanism controls positioning of the sleeve between the retracted and extended positions, and locks the sleeve relative to the shaft. When the intervertebral device is releasably engaged by the engagement member, and the sleeve is in the extended position, the anti-rotation member engages the intervertebral device and prevents rotation of the intervertebral device when releasing the engagement member from the intervertebral device.

Abstract:
An intervertebral implant comprises a first member for engaging a first vertebral body and a second member for engaging a second vertebral body. The first member has a first surface with a first curve, and the second member has a second surface with a second curve. The first member is translatable with respect to the second member and the second curve is positioned within the first curve to bias the first and second curved surfaces towards central alignment along a longitudinal axis passing through the first and second vertebral bodies.
A spinal rod having first and second end members. The end members may be flexible or rigid. An expandable intermediate section is positioned between the first and second end members. The intermediate section may be axially expandable upon the introduction of a substance into a port that may be located in either of the first and second end members or the intermediate section. The intermediate section may be expandable between a first size, where the first and second end members are spaced a first distance apart, and a second enlarged size, where the first and second end members are spaced a second greater distance apart.

Abstract:
A motion-preserving implant device for insertion between two bones is disclosed. The motion-preserving implant includes a first plate for engaging with a first bone and a second plate for engaging with a second bone. An articulation member is positioned between the two plates and a motion-controlling member attached to one or both of the plates. In some embodiments, the motion-controlling member is configured to constrain, dampen, and/or bumper the relative motion between the two plates.
Methods And Devices For Treating A Multi-Level Spinal Deformity

International Classification:
A61B 17/88
US Classification:
606279
Abstract:
The present application discloses methods for treating a multi-level spinal deformity. The methods may include inserting a tether in a minimally-invasive manner through an entrance incision. The tether is moved along the spine and positioned to reduce and/or eliminate the deformity. Once the tether is positioned along the spine, the tether may be secured to the vertebral members. In one embodiment, the tether includes a rigid section and a flexible section. The tether may be positioned within the spine with the rigid section extending along a first length of the spine and the flexible section extending along a second length of the spine. The different sections provide different corrective forces to the spine to reduce and/or eliminate the spinal deformity. In one embodiment, the rigid section extends along an apex of the spinal deformity.

Abstract:
Spinal support members having varying stiffnesses are disclosed. In one embodiment, an elongated spinal prosthetic includes a pair of curved elongated portions. The portions are formed of materials having different stiffness characteristics such that the stiffness of the prosthetic varies along its length. In another embodiment, an elongated spinal implant includes a pair of threadedly engaged elongated sections. The first section is formed of a first material having a first rigidity. The second section has an inner portion formed of the first material and an outer portion formed of a second material. The second material is less rigid than the first material. In another embodiment, a modular spinal rod is provided. The modular spinal rod includes a pair of connectable rod portions with different stiffness characteristics. In yet another embodiment, a kit for a modular spinal rod includes a plurality of connectable modular rod portions having different stiffness characteristics.
