Patent number: 11357645Abstract: An implant device for use in achieving spinal fusion, includes an implant having an implant body. The device includes a graded radiopacity calibration tool integrated with the implant body. The tool has a plurality of graded levels of radiopacity representative of a range of bone density parameter amounts. Each of the graded levels corresponds to a different bone density parameter amount. A method is provided that uses the device to determine a degree of one of bone maturity, strength, osteoporotic state, state of healing and state of degrading bone tissue based on a comparison of a bone at the site in the image and radiopacity correlated from a calibration standardized curve defined by the standard, with a range of grey levels representative of degrees of one of the bone maturity, the strength, the osteoporotic state, the state of healing and the state of degrading bone tissue.Type: GrantFiled: April 17, 2020Date of Patent: June 14, 2022Assignee: WARSAW ORTHOPEDIC, INC.Inventors: Todd Boyce, Gretchen S.

Patent number: 10080661Abstract: An osteoimplant composite comprising a plurality of particles of an inorganic material, a bone substitute material, a bone-derived material, or any combination thereof; and a polymer material with which the particles are combined. The composite is either naturally moldable or flowable, or it can be made moldable or settable. After implantation, the composite may be set to provide mechanical strength to the implant. The inventive composite have the advantage of being able to fill irregularly shape implantation site while at the same time being settable to provide the mechanical strength required for most orthopedic applications. The invention also provides methods of using and preparing the moldable and flowable composites.Type: GrantFiled: May 9, 2016Date of Patent: September 25, 2018Assignee: Warsaw Orthopedic, Inc.Inventors: Deger C.

Patent number: 10028837Abstract: A covering for delivering a substance or material to a surgical site is provided. The covering, with substance provided therein, may be referred to as a delivery system. Generally, the covering may be a single or multi-compartment structure capable of at least partially retaining a substance provided therein until the covering is placed at a surgical site. Upon placement, the covering may facilitate transfer of the substance or surrounding materials. For example, the substance may be released (actively or passively) to the surgical site. The covering may participate in, control, or otherwise adjust, the release of the substance.Type: GrantFiled: May 6, 2016Date of Patent: July 24, 2018Assignee: Warsaw Orthopedic, Inc.Inventors: Guobao Wei, Keyvan Behnam, Nanette Forsyth, John Winterbottom, James Beisser, Todd Boyce, Mohamed Attawia, Cristy J.

Patent number: 9415136Abstract: An osteoinductive demineralized bone matrix, corresponding osteoimplants, and methods for making the osteoinductive demineralized bone matrix are disclosed. The osteoinductive demineralized bone matrix may be prepared by providing demineralized bone and altering the collagenous structure of the bone. The osteoinductive demineralized bone matrix may also be prepared by providing demineralized bone and compacting the bone, for example via mechanical compaction, grinding into a particulate, or treatment with a chemical. Additives such as growth factors or bioactive agents may be added to the osteoinductive demineralized bone matrix. The osteoinductive demineralized bone matrix may form an osteogenic osteoimplant. The osteoimplant, when implanted in a mammalian body, may induce at the locus of the implant the full developmental cascade of endochondral bone formation including vascularization, mineralization, and bone marrow differentiation.Type: GrantFiled: May 23, 2014Date of Patent: August 16, 2016Assignee: Warsaw Orthopedic, Inc.Inventors: Keyvan Behnam, Nanette Forsyth, James Russell, John Winterbottom, Todd Boyce

Publication number: 20060100498Abstract: A procedure for determining a plan for cutting a bone sample for use as an implant provides scanning the bone with a CT scanning system to provide slice images of the bone. The scanning system then determines the cortical or cancellous bone dimensions and density of the bone. Determining such dimensions and density permits accurate planning and preparation of an implant graft that is correlated to the predetermined plan without waste of bone through cutting test specimens to determine the bone parameters. Other images techniques that provide slice images are also disclosed.Type: ApplicationFiled: July 17, 2003Publication date: May 11, 2006Inventors: Todd Boyce, Stephen Mercadante

Publication number: 20060015184Abstract: An implant system for fusing vertebrae includes a variety of shapes that may be stacked to accommodate different intervertebral spacings and curvatures. The implants comprise polymer-bone composites that have osteogenic properties. By selection of an appropriate set of shapes, the surgeon can tailor the overall shape of the implant before or during surgery, in order to best match the shape of the intervertebral cavity for a particular patient.Type: ApplicationFiled: January 31, 2005Publication date: January 19, 2006Inventors: John Winterbottom, Ryan Belaney, David Knaack, Todd Boyce, Lawrence Shimp, Samuel Lee, David Kaes, Marc Burel
