Patent number: 11925561Abstract: There are provided herein methods and products resulting therefrom. The methods include attaching a pre-fabricated porous ingrowth structure to a substrate by applying heat, or creating and bonding an in-situ-formed porous ingrowth structure from beads on a substrate by applying heat. In some embodiments, an oxidized metal surface of the substrate is diffusion hardened during the heating process. In some embodiments, a vacuum is applied during the heating process. In some embodiments, pressure is applied during the heating process. Also provided herein are assemblies for compressing the pre-fabricated porous ingrowth structure or the beads onto the substrate during the heating process.Type: GrantFiled: August 1, 2022Date of Patent: March 12, 2024Assignees: Smith & Nephew, Inc., Smith & Nephew Orthopaedics AG, Smith & Nephew Asia Pacific Pte. LimitedInventors: Marcus L. Scott, Vivek D. Pawar, Carolyn L. Weaver, Daniel A Heuer, Roger R. Dees, Jr., Forrest A. James, Matthew J. Quick

Publication number: 20190337055Abstract: The present disclosure provides methods to improve the properties of a porous structure formed by a rapid manufacturing technique. Embodiments of the present disclosure increase the bonding between the micro-particles 5 on the surface of the porous structure and the porous structure itself without substantially reduce the surface area of the micro-particles. In one aspect, embodiments of the present disclosure improves the bonding while preserving or increasing the friction of the structure against adjacent materials.Type: ApplicationFiled: July 16, 2019Publication date: November 7, 2019Inventors: Marcus L. Scott, Lu Gan, Vivek D. Pawar, Stanley Tsai
