Patent number: 11684478Abstract: 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.Type: GrantFiled: April 8, 2022Date of Patent: June 27, 2023Assignee: Howmedica Osteonics Corp.Inventors: Robert W.

Publication number: 20220387163Abstract: An implant is produced by fabricating first and second layers. The first layer of repeated and truncated building units is fused together to define pores. The second layer of repeated and truncated building units are fused together to define pores and fused onto the first layer of truncated building units. The first and the second layers form at least part of a porous portion of the implant. The formed porous portion is attached onto a base portion of an implant. The truncated building units of each of the first and the second layers are in the form of spatially overlapping three-dimensional shapes.Type: ApplicationFiled: June 1, 2022Publication date: December 8, 2022Inventors: Gearoid Walsh, Lewis Mullen, John Scanlan, Robert W.

Patent number: 9445902Abstract: 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.Type: GrantFiled: October 20, 2010Date of Patent: September 20, 2016Assignee: Howmedica Osteonics Corp.Inventors: Robert W.
