Patent number: 11440118Abstract: An apparatus and method are provided for manufacturing an orthopedic prosthesis by resistance welding a porous metal layer of the orthopedic prosthesis onto an underlying metal substrate of the orthopedic prosthesis. The resistance welding process involves directing an electrical current through the porous layer and the substrate, which dissipates as heat to cause softening and/or melting of the materials, especially along the interface between the porous layer and the substrate. The softened and/or melted materials undergo metallurgical bonding at points of contact between the porous layer and the substrate to fixedly secure the porous layer onto the substrate.Type: GrantFiled: August 19, 2019Date of Patent: September 13, 2022Assignee: Zimmer, Inc.Inventors: Joseph R. Vargas, Steven Seelman, Clarence M. Panchison, Emmanuel L. Uzuyem, Carlos Holguin

Patent number: 9814583Abstract: The modular stem component may include a shaft portion, a head, and a sleeve. The shaft portion is configured for receipt within the intramedullary canal of a bone and the head is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib defining a flange extending therefrom. The sleeve, which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends and has a bore extending therethrough. The bore is configured to facilitate sliding receipt of the sleeve on the head.Type: GrantFiled: May 8, 2007Date of Patent: November 14, 2017Assignee: Zimmer, Inc.Inventors: Dennis R. Aquilo, John E.

Patent number: 9718241Abstract: An orthopedic component having multiple layers that are selected to provide an overall modulus that is substantially lower than the modulus of known orthopedic components to more closely approximate the modulus of the bone into which the orthopedic component is implanted. In one exemplary embodiment, the orthopedic component is an acetabular shell. For example, the acetabular shell may include an outer layer configured for securement to the natural acetabulum of a patient and an inner layer configured to receive an acetabular liner. The head of a femoral prosthesis articulates against the acetabular liner to replicate the function of a natural hip joint. Alternatively, the inner layer of the acetabular shell may act as an integral acetabular liner against which the head of the femoral prosthesis articulates.Type: GrantFiled: January 16, 2014Date of Patent: August 1, 2017Assignee: Zimmer, Inc.Inventors: Kirt Case, Oludele O. Popoola, Robby Kissling, Brion R. Mimnaugh, Archie Newsome, Clarence M. Panchison, Dirk Pletcher, Randy Schlemmer, Zhibin Fang, Juan Vivanco, Alicia Rufner, John Knight

Publication number: 20150014397Abstract: Methods for bonding a porous tantalum structure to a substrate are provided. The method includes placing a compressible or porous interlayer between a porous tantalum structure and a cobalt or cobalt-chromium substrate to form an assembly. The interlayer comprising a metal or metal alloy that has solid state solubility with both the substrate and the porous tantalum structure. Heat and pressure are applied to the assembly to achieve solid state diffusion between the substrate and the interlayer and the between the porous tantalum structure and the interlayer.Type: ApplicationFiled: September 29, 2014Publication date: January 15, 2015Inventors: Gregory M. Hippensteel, Lawrence F. Peek, Jeffrey P. Anderson, Devendra Gorhe, Steve M. Allen, Clarence M. Panchison, David M. Miller, Joel G. Scrafton, Casey Harmon
