Abstract: The present invention provides a cervical plate and bone graft(s) that are capable of being attached prior to insertion of the bone graft into an intervertebral space. After insertion, the vertebrae hold the bone graft and cervical plate in place facilitating the anchoring of the cervical plate to the vertebrae. Further, a screw back out prevention device can be coupled to the cervical plate to prevent screws from backing out.

Abstract: The present invention relates to an aneurysm stent having a base and connector. The base has a vessel facing side and an aneurysm facing side, and is shaped to cover an aneurysm sufficiently. The connector is coupled to the aneurysm facing side of the base such that when deployed the connector is adapted to extend partially into the aneurysm to anchor the base about the aneurysm and alter flow into the aneurysm. Futher, the stent can be used as a delivery mechanism to deliver growth factor.

Abstract: Deposition apparatus incorporating either a single or multiple filtered cathodic arc (FCA) source for depositing coatings such as tetrahedral amorphous carbon (TAC); metal oxides; compounds and alloys of such materials onto various types of substrates, such as metals semiconductors, plastics ceramics and glasses. Substrates are moved through the plasma beam(s) of the FCA source(s) and beam scanning increases deposition area. Macroparticles are filtered by a double bend filter duct.

Abstract: The present invention comprises an artificial disc for a spine and methods of implanting the same. The artificial disc includes an upper and lower endplate to be coupled to upper and lower vertebral bodies. A core of shaped memory alloy material is placed between the endplates to mimic the spinal disc.

Abstract: The present invention relates to an aneurysm stent having a base and connector. The base has a vessel facing side and an aneurysm facing side, and is shaped to cover an aneurysm sufficiently. The connector is coupled to the aneurysm facing side of the base such that when deployed the connector is adapted to extend partially into the aneurysm to anchor the base about the aneurysm and inhibit flow into the aneurysm.

Abstract: A method for controlling the extraction of gold from a gold ore by the cyanidation process in which a leaching step including the addition of a lead compound, which is typically lead nitrate or other lead salt, is used. In order to maintain stable conditions in the leaching process, and to use the leaching reagents efficiently, an analysis step is used to monitor the concentration of thiocyanate in the cyanidation step. This value has been found to be directly related to the rate of addition of the lead compound in the pre-leaching or leaching step. Further, the rate of addition of lead compound is also directly related to both the time required for, and the efficiency of, the cyanidation step. By establishing a target value, and a preferred range, for the thiocyanate concentration based on the properties of the ore being processed, optimal extraction conditions can be established in the leaching process and maintained by monitoring the thiocyanate concentration.
