Patent number: 10391593Abstract: A plurality of individual medical devices is created that define a medical device family. Within the family of medical devices, each of the plurality of medical devices has at least one dimension that, within an acceptable tolerance, is substantially equal to the same dimension of another of the plurality of medical devices. Thus, for each medical device in the family, another, corresponding medical device has at least one substantially similar dimension. For example, a first medical device may have a first value for a dimension and a second medical device may have a second value for the same dimension that is equal to one of the sum of the second dimension and the acceptable tolerance or the difference between the second dimension and the acceptable tolerance. Thus, each of the plurality of medical devices varies from another of the plurality of medical devices by the acceptable tolerance.Type: GrantFiled: May 19, 2017Date of Patent: August 27, 2019Assignee: Zimmer, Inc.Inventors: Adam H. Sanford, Dean M. Acker, Jeffrey D. Brown, Brian D. Earl, John E. Pendleton

Patent number: 9707316Abstract: Polymer compositions having one or more antioxidants providing high crosslink density and improved oxidation resistance to the polymer composition and methods for making same. Such polymer compositions can be used to make orthopedic implants.Type: GrantFiled: May 9, 2016Date of Patent: July 18, 2017Assignee: Zimmer, Inc.Inventors: Brian H. Thomas, Dean M.

Publication number: 20160250381Abstract: The present disclosure is directed to polymer compositions having one or more antioxidants providing high crosslink density and improved oxidation resistance to the polymer composition and methods for making same. Such polymer compositions can be advantageously used to make orthopedic implants. The disclosure also provides methods for selecting antioxidants providing desirable properties to the polymer composition. In one embodiment, a measure of OIT can be used to select the antioxidant and antioxidant blend. In another embodiment, measurements of OIT and OI-rate can be used to select the one or more antioxidants. In another embodiment, the product of OIT and crosslink density can be calculated to predict wear resistance and oxidation resistance of a polymer composition including one or more antioxidants.Type: ApplicationFiled: May 9, 2016Publication date: September 1, 2016Inventors: Brian H. Thomas, Dean M. Acker, Ray Gsell, Norman Stark

Publication number: 20150257888Abstract: Prosthetic hip stems for use in prosthetic hip joints and, in particular, provides prosthetic hip stems that are designed to achieve more optimized outcomes with certain types of patient anatomy, such as the anatomy of female patients and/or patients having osteoporosis. Each hip stem in a family or set of hip stems has diaphyseal width, metaphyseal width, offset, and head height dimensions. In a set of hip stems of increasing nominal size, the diaphyseal width dimension increases substantially non-proportionally to the corresponding increase of the metaphyseal width, offset, and head height dimensions, thereby providing a family or set of hip stems that is particularly adapted for patients having osteoporosis, in which the cortical bone of the diaphysis of the femur becomes thinner with progression of the osteoporosis.Type: ApplicationFiled: May 18, 2015Publication date: September 17, 2015Inventors: Dean M. Acker, Stephen H. Hoag, Danielle L. Whitlock, Wayne Paprosky

Patent number: 8613938Abstract: A bone void filler composition is described containing an acidic mineral component that contains a calcium source and a phosphate source or a lower alkyl carboxylate source; an osteoinductive component that contains demineralized bone; and a three-dimensional, osteoconductive biologically acceptable carrier component that contains a collagenous material. The bone void filler composition may be in the form of a sponge or in the form of a paste or putty used to form a sponge or is obtained from particulated sponge, or that forms after a sponge is rehydrated. A pre-mixed bone void filler composition is described containing the acidic mineral component or the lower alkyl carboxylate source; the osteoinductive component; and a biologically acceptable carrier component that contains a liquid carrier. Methods of making and using the compositions are also described. The ratio of demineralized bone component to acidic mineral component may range from about 0.5:1 to about 80:1.Type: GrantFiled: November 15, 2011Date of Patent: December 24, 2013Assignee: Zimmer Orthobiologics, Inc.Inventors: Rama Akella, Ian Ross Garrett, Hai Bo Wen, Shuliang Li, Dean M.
