  • Publication number: 20180339486
    Abstract: A packaging system includes a packaging unit and an article. The packaging unit includes a solid layer, a porous layer and a plastic layer with a cavity. The cavity is configured to receive and secure the article in an opening defined by the cavity that is flexible between a first and a second dimension. The packaging unit is fabricated by a 3D printing process. A tensioning device of a 3D printing machine tensions a feed filament during the 3D printing process.

  • Publication number: 20180333780
    Abstract: A porous apparatus includes a first layer and a second layer. The second layer has a plurality of struts. At least some of the struts define a porous geometry defining a plurality of faces, at least one of the plurality of the faces at least partially confronting the first layer. Each face is bounded by intersecting struts at vertices. Less than all of the vertices of each face of the porous geometry at least partially confronting the first layer are connected by a strut to the first layer. A process of producing the at least partially porous structure includes depositing and scanning metal powder layers. At least some of the scanned metal powder layers form either one or both of a portion of a first section of the structure and a portion of a second section of the structure formed by at least the struts defining the porous geometry.

  • Patent number: 9445902
    Abstract: One embodiment of the implant comprises a porous metal bone ingrowth portion (14) having a first side connected to a high density or solid (fully dense) metal portion (16) which in turn has an opposite side connected to a porous metal soft tissue ingrowth portion (12) thus forming a sandwich structure with the high density or fully dense portion in the middle. The implant may be made of a resorbable material such as an alloy of magnesium. Alternately, the alloy can be selected from the group consisting of calcium, iron, yttrium and lithium. The porous metal soft tissue ingrowth portion (12) has porosity characteristics allowing cartilage to interdigitate with the pores and extend outwardly beyond the platform of the metal surface towards a joint capsule. The solid or fully dense intermediate layer 16 may have some porosity, however that porosity prevents either bone tissue or cartilage tissue from migrating therethrough.

  • Patent number: 7842095
    Abstract: A temporary femoral implant system has a porous mold and a femoral component. The system fits at least partially in a femoral cavity. The mold has a wall with an interior surface and an exterior surface forming an interior space for receiving an antibiotic bone cement. The mold allows the antibiotic to diffuse through the wall to the exterior surface. The femoral component has a stem portion received within the mold. A method of using the implant system includes providing an implant system comprising a mold and a femoral component, inserting the mold into the femoral cavity with the exterior surface facing the femoral cavity, inserting the stem portion of a femoral component into the interior space of the mold and filling the interior space of the mold with an antibiotic bone cement.
