  • Publication number: 20200121822
    Abstract: A fluid filtration system is shown. The fluid filtration system utilizes a one-piece or multiple piece containers having a plurality of radiation-transmissible media adapted to receive light, such as ultraviolet light, white light or other wavelength light. The radiation-transmissible media are situated in the container and at least one or a plurality of radiation sources, such as ultraviolet lamps, are situated in an array in proximity to the radiation-transmissible media. The radiation-transmissible media interrupts the flow and velocity of the fluid stream passing through the container to extend the duration of radiation for any contaminants and also provide enlarged surface areas for the contaminants to be received and ultimately exposed to the radiation. In one example, the radiation-transmissible media may be tubular or spherical sections that are hollow or solid and made of quartz.

  • Publication number: 20190328541
    Abstract: An implant assembly is shown and described. The implant has at least one or a plurality of elastic, resilient or flexible arms that each have a detent adapted to retain at least one screw in a locked position in the implant. At least one of the arms has a portion that extends into a screw aperture such that an arm axis is generally parallel to the axis of the screw after the screw is received in the implant. In another embodiment, means or a system for locking the multi-component implant members together is shown.

  • Patent number: 10285770
    Abstract: A bone plating system and implant card having at least one or a plurality of plates. The bone plating system and implant card has a card member or support having the at least one or a plurality of plates that are integrally, monolithically, or otherwise formed in or adhered to the card member so that the at least one or plurality of plates can be detached or removed from the card member manually or with a cutting instrument or tool. In one illustrative embodiment, the card member comprises a plurality of different plates that are the necessary plates for a single surgical procedure, such as a craniotomy. The bone plating system or implant card allows for selection of plates of varying sizes, shapes and configurations in a single card member, which could be generally planar or could also be non-planar or lie in a plane that is not flat.

  • Patent number: 9987052
    Abstract: A modular interspinous system is shown having a first plate, a generally opposing second plate and a modular insert that may be removably or permanently secured to the first plate. The first plate has a coupling means, coupler or connection system in the form of a screw that may be permanently or non-permanently docked or supported in the first plate. The modular insert is adapted, sized and shaped to expose at least a portion of the screw thread of the screw and that portion may cooperate with at least one mating female thread in the second plate, thereby enabling a user to rotate the screw in order to drive the first and second plates towards or away from each other and, for example, into compression with bone.
