| 20090222098 | Spinal nucleus replacement with varying modulus - An intervertebral disc augmentation implant comprises an implant body adapted for implantation within an annulus fibrosis the intervertebral disc, adjacent to an at least partially intact nucleus pulposus of the intervertebral disc, and comprising a core area, a peripheral wall area, a top face area, and a bottom face area. The implant body is formed from at least one material and the implant body has a modulus of elasticity gradient that gradually changes from the core area of the implant body to the peripheral wall area of the implant body. | 09-03-2009 |
| 20090222099 | Self Centering Nucleus Implant - An intervertebral disc augmentation implant for implantation between a pair of vertebral bodies comprises an elastically deformable outer casing having at least one thickness dimension and a core member having isotropic material properties. The core member is entirely encased within the outer casing and has a height dimension along an axis defined by the pair of vertebral bodies. The modulus of elasticity of the core member is greater than a modulus of elasticity of the outer casing, and the height dimension of the core member is greater than the at least one thickness dimension of the outer casing. | 09-03-2009 |
| 20090287250 | METHOD AND APPARATUS FOR REPLACING THE FUNCTION OF FACET JOINTS - A system and method is provided for replacing the functions of a facet joint between a superior vertebra and an inferior vertebra without necessarily requiring an anatomical implant. The method includes: providing one or more flexible posterior devices to replace main functions of the facet joint; and adapting a first one of the one or more posterior devices for a first attachment to a first pedicle, and a second attachment to a second pedicle. | 11-19-2009 |
| 20090312797 | Minimally invasive instruments and methods for inserting implants - Instruments and methods for inserting one or more implants to a surgical site in a patient in a surgical procedure, including minimally invasive surgical procedures are provided. The implant is mountable to the instrument in a reduced profile orientation and after insertion is manipulated with the insertion instrument to the desired orientation. | 12-17-2009 |
| 20090312806 | Formed in Place Corpectomy Device - An inflatable corpectomy device comprises a balloon, which defines a cavity for receiving a hardenable media. The device can be inserted in an un-inflated form into a space formerly occupied by a diseased or damaged vertebrae bone. When inflated with a hardenable material, the device expands and fills the space. Various bone anchors or plates can be used in combination with the inflatable device to bridge the space and stabilize the spine while the device hardens. | 12-17-2009 |
| 20110015680 | SYSTEMS AND METHODS FOR INTRAVERTEBRAL REDUCTION - Intravertebral reduction systems are provided to restore a deformed or damaged vertebral body to a desired configuration. The reduction systems can include a plurality of reduction elements sequentially positionable in the intravertebral space for reduction of the same. The reduction systems can also include reduction elements that include a linear insertion configuration and are deformable transversely to the linear insertion configuration in the intravertebral space. | 01-20-2011 |
| 20110022093 | SYSTEMS AND METHODS FOR SPINAL STABILIZATION WITH FLEXIBLE ELEMENTS - Systems and methods are provided for spinal stabilization with flexible elements and other elements engaged to the vertebrae. Also provided are instruments and methods for insertion of the flexible stabilization elements and other elements and for reduction of displacement between adjacent vertebrae in a minimally invasive surgical approach. | 01-27-2011 |
| 20110106187 | Instruments and methods for stabilization of bony structures - The present invention relates to methods and instruments for placing a brace or connecting element into an animal subject for engagement with anchors secured in the animal subject. The installation instrument includes anchor extensions coupled to the anchors. The instrument is movable with respect to the anchors to position the connecting element in a position more proximate the anchors. | 05-05-2011 |
