| 20120029643 | RESTORATIVE DEVICE - The present invention provides a disc restoration system for relieving symptoms of a degenerative disc, comprising: a) a percutaneously insertable expandable element (88) adapted to be (i) inserted in between two adjacent vertebraes of the spinal cord; and, (ii) expanded to form a scaffold; said scaffold provides mechanical support to said two adjacent vertebraes so as to restore said degenerative disc to approximately the dimensions of a normal disc; b) an injectable filler having a first flowable state, and a second non-flowable set state; the filler is configured for being introduced, in said first flowable state, into a confined volume formed by the expandable element and the tissues, following the full expansion of said expandable element in said disc; and, following introduction of said filler, said filler is adapted to set into said second non-flowable state; such that following setting of said filler into said second state said disc is internally supported by said set filler. | 2012-02-02 |
| 20120029644 | Compliant Interbody Fusion Device with Deployable Bone Anchors - An interbody fusion implant with deployable bone anchors includes a support member, a monolithic body that accommodates the support member, and a longitudinal hole along a vertical length of the support member. The support member includes a first end and a second end. The second end includes two flanges. The flanges are configured to dig into an endplate of a vertebral body. The flanges of the support member provide a location fixation on an implantation of the interbody fusion implant into the vertebral body. The support member may also include at least one of a clip shaped support member and an I-shaped support member. The I-shaped support member may allow a rigidity and a support in flexion-extension through a living-hinge positioned in a middle of the I-shaped support member. The longitudinal hole sustains loads imported on the interbody fusion implant and allows the interbody fusion implant to flex freely. | 2012-02-02 |
