  • Publication number: 20250041066
    Abstract: An example implant device includes a base having a surface that mates with bone, and a plurality of tapered protrusions positioned on the base and extending from the surface of the base that mates with bone. A surface of the plurality of tapered protrusions includes a textured surface to increase area for bone growth. An example method for inserting the implant device into bone includes forcing the plurality of tapered protrusions of the implant device into the bone, and securing the implant device in place without cement due to the plurality of tapered protrusions cutting into the bone for fixation of the implant device.

  • Patent number: 5782269
    Abstract: A check valve normally blocks fluid flow from a bore to a passage and includes a spring normally holding a ball in sealing engagement with a valve seat to form a primary metal-to-metal hard seal. Another spring normally holds a poppet in engagement with another valve seat causing an annular protuberance formed on the poppet to sealingly engage a resilient seal to provide a more positive secondary soft seat seal. The poppet is unseated from the valve seat by a stem of a piston prior to the ball being unseated from the valve seat by a guide stem of the poppet so that the soft seal is opened at essentially zero flow conditions.
