  • STRUCTURAL POROUS BIOMATERIAL AND IMPLANT FORMED OF SAME
    Publication number: 20210045880
    Abstract: A method for manufacturing an implant includes pre-selecting a designed porous microstructure having a lattice composed of cells, including selecting one or more predetermined cell topologies, selecting a predetermined porosity, cell strut thickness and packing factor of the lattice, and selecting an arrangement of the cells within the lattice to have a periodic and/or aperiodic arrangement. Additive manufacturing is used to form the designed porous lattice microstructure in at least a region of at least an external surface of the implant.

  • Structural porous biomaterial and implant formed of same
    Patent number: 10842634
    Abstract: An implant comprising a porous microstructure is disclosed which has an external surface, where at least a region of the external surface is formed of the porous microstructure. The microstructure is defined by at least one lattice of cells. Each cell has a predetermined cell topology and a plurality of edges. One or more of the edges of each cell connect to an adjacent cell along a corresponding edge thereof. Collectively, the cells have a periodic or aperiodic arrangement within the at least one lattice.
    Type: Grant

  • Hose clip apparatus
    Patent number: 4267622
    Abstract: Clip apparatus for use in securing a member such as a hose to a pipe or the like. The apparatus includes a housing secured to one end of a spirally configured flexible strip. A rotatable driving member carried by the housing is formed with threads engageable with complementary threads formed on the strip. Rotation of the driving member causes expansion and contraction of the strip relative to the pipe or the like. Slidable movement of the driving member disengages its threads from those of the strip.
