Abstract: Modular spinal prosthesis having one of both of adaptable and configurable components are provided. The modular spinal prosthesis described herein provide an artificial articular configuration to replace damaged, worn or otherwise removed spinal facet elements.

Abstract: Cephalad and caudal vertebral facet joint prostheses and methods of use are provided. The cephalad prostheses are adapted and configured to be attached to a lamina portion of a vertebra without blocking a pedicle portion of the cephalad vertebra.

Abstract: An adaptable spinal facet joint prosthesis, including a pedicle fixation element; a laminar fixation element; and a facet joint bearing surface having a location adaptable with respect at least one of the pedicle fixation element and the laminar fixation element. The invention also includes a method of implanting an adaptable spinal facet joint prosthesis including the steps of determining a desired position for a facet joint bearing surface; and attaching a prosthesis comprising a facet joint bearing surface to a pedicle portion of a vertebra and a lamina portion of a vertebra to place the facet joint bearing surface in the desired position. The invention also provides a facet joint prosthesis implant tool including a tool guide adapted to guide a vertebra cutting tool; and first and second fixation hole alignment elements extending from the saw guide.

Abstract: The invention discloses methods and devices for repairing, replacing and/or augmenting natural facet joint surfaces and/or facet capsules. A facet joint restoration device of the invention for use in a restoring a facet joint surface comprises: a cephalad facet joint element comprising a flexible member adapted to engage a first vertebrae and an artificial cephalad joint; and a caudad facet joint element comprising a connector adapted for fixation to a second vertebrae and an artificial caudad joint adapted to engage the cephalad facet joint.

Abstract: The present invention relates to methods and devices for the treatment of disc disease and spinal deformities with an artificial disc replacement.

Abstract: An intermittent pressure module for controlling the position of a valve between two positions comprising diaphragm means; a plurality of ports associated with said diaphragm means for exposing said diaphragm means to a selected pressure in said first position, and ambient pressure in said second position; swing means associated with said diaphragm means and said valve means for intermittently displacing said valve means when said diaphragm means is exposed to said selected pressure in said first position and ambient pressure in said second position.

Abstract: Cephalad and caudal vertebral facet joint prostheses and methods of use are provided. The cephalad prostheses are adapted and configured to be attached to a lamina portion of a vertebra without blocking a pedicle portion of the cephalad vertebra. In some embodiments, the prosthesis is attached with a non-invasive support member, such as a clamp. In other embodiments, a translaminar screw may be used for additional fixation.

Abstract: A method of and apparatus for extending the life of fountain solutions used in commercial printing presses comprises withdrawing fountain solution from the dampener recirculation system of a printing press and directing the withdrawn fountain solution through a sediment prefilter, a separation filter, and a post treatment filter. The sediment prefilter preferably comprises a melt blown polypropylene filter; the separation filter preferably comprises a diatomaceous earth filter; and the post treatment filter preferably comprises a zeolite filter.

Abstract: The present invention relates to a locking mechanism and method of fixation, such as the fixation of a fixation device like a bone screw and of a stabilization device like a rod to the spine. The locking mechanism includes a seat and a locking element. The seat includes a bottom portion configured to receive the fixation device such that a socket of the bottom portion engages part of the fixation device and prevents the fixation device from passing entirely therethrough. The seat further includes a side portion configured to receive the stabilization device and a locking element. The locking element, when fully engaged with the side portion of the seat, causes locking of the relative positions of the fixation device and the stabilization device.
