Abstract: The present invention generally relates to an extendable intervertebral disc prosthesis system and assemblies thereof. A prosthesis system of certain embodiments includes a superior and inferior endplate assembly as well as an inner core disposed therebetween. Each endplate assembly includes two plates that slide relative to one another longitudinally such that the endplate assembly moves from an unextended position having a first width to an extended position having a second width greater than the first width. The present invention also provides a telescoping intervertebral disc prosthesis system. Additionally, the present invention provides methods for implanting extendable intervertebral disc prosthesis systems and their assemblies. The present invention also provides a kit for implanting an extendable intervertebral disc prosthesis system, including an insertion tool and an extendable intervertebral disc prosthesis system.

Abstract: The present invention regards linking spinal vertebrae to provide support and alignment of one or more vertebrae. The various systems, methods, devices and kits that embody the invention may employ a vertebrae crossover connector to link or otherwise connect one or more vertebrae in a column of vertebrae. These connectors may be positioned between anchors added to the vertebrae and may span the center of the spinal column when the connectors are positioned between the anchors. In certain embodiments each crossover connector may include one or more stretchable couplings that can stretch and resist tensile loads placed on them when the spinal column is stationary and in various ranges of motion. The crossover connector may also include a main body that may resist compressive loads placed on the crossover connector when the spinal column is in various ranges of motion in certain positions.

Abstract: An interspinous distraction kit is provided with a distal anchor comprising a locking section moveable from a radially un-extended position in a non-deployed configuration to a radially extended position in a deployed configuration. A method for maintaining a space between adjacent spinous processes by unilateral access to the spinous processes is also provided.
