Patent number: 7753963Abstract: Selectively demineralized bone-derived implants are provided. In one embodiment, a bone sheet for implantation includes a demineralized field surrounding mineralized regions. In another embodiment, a bone defect filler includes a demineralized cancellous bone section in a first geometry.

Patent number: 7641666Abstract: The present invention relates generally to a prosthetic spinal disc for replacing a damaged disc between two vertebrae of a spine. The present invention also relates to a method for implanting a prosthetic spinal disc via posterior or posterior lateral implantation. Other surgical approaches for implanting the prosthetic disc may also be used. The present invention also involves a method for implanting the prosthetic spinal disc while either avoiding or minimizing contact with the spinal cord and nerve rootlets, or reducing the time and extent that they need to be repositioned during implantation.Type: GrantFiled: July 30, 2004Date of Patent: January 5, 2010Assignee: Globus Medical, Inc.Inventors: David C.

Patent number: 7491237Abstract: An allogenic implant for use in intervertebral fusion is formed from one or more two pieces. The pieces are made from bone, and are joined together to form an implant having sufficient strength and stability to maintain a desired distance between first and second vertebrae in a spinal fusion procedure. The implant pieces may be formed of cortical bone and connected by dovetail joints, and at least one cortical bone pin may be provided to lock the pieces together and to add strength to the implant. Teeth are formed on the vertebra engaging surfaces of the implant prevent short-term slippage of the implant.Type: GrantFiled: March 28, 2005Date of Patent: February 17, 2009Assignee: Synthes USA, LLCInventors: Brandon L Randall, Roger D Goodwin, Dominique Messerli, Jacqueline Myer, Robert J Delurio, Michael L Boyer, II, Christopher M Angelucci

Patent number: 7473277Abstract: Skeletal reconstruction cages include a central body having first and second ends, a first end cap coupled to one end of the central body, and a second end cap coupled to the other end of the central body. At least two of the central body, first end cap, and second end cap are formed from bone. Each of the central body, first end cap, and second end cap may be provided in different sizes so that cages with varying overall heights, and related angulations, may be created.Type: GrantFiled: January 4, 2006Date of Patent: January 6, 2009Assignee: Synthes (U.S.A.)Inventors: Michael L.

Publication number: 20040210222Abstract: Implants for maintaining a distance between cut spinal bones are disclosed. The implants are made of metal, polymer or bone allograft having ends configured to conform to the cut bone ends. The implants have hollow regions for packing osteogenic material. The implant ends have surface projections to reduce slippage. Implants made of bone allograft also have spine contacting ends made of demineralized bone to speed fusion of spine and implant; they may also have bone flaps to fix the implant to the spine. Methods of using the implants are also disclosed.Type: ApplicationFiled: May 12, 2004Publication date: October 21, 2004Inventors: Christopher M. Angelucci, Michael L. Boyer, David C.
