  • Osteoinductive bone material
    Patent number: 8454988
    Abstract: Osteogenic bone implant compositions that approximate the chemical composition of natural bone are provided. The organic component of these implant compositions is osteoinductive despite the presence of the inorganic component and, further, is present in an amount sufficient to maximize the regenerative capabilities of the implant without compromising its formability and mechanical strength. The composition may be an osteoinductive powder, including demineralized bone matrix (DBM) particles, a calcium phosphate powder, and, optionally, a biocompatible cohesiveness agent. The powder may be combined with a physiologically-acceptable fluid to produce a formable, osteoinductive paste that self-hardens to form a poorly crystalline apatitic (PCA) calcium phosphate having significant compressive strength. The bone implant materials retain their cohesiveness when introduced at an implant site and are remodeled into bone in vivo.
    Type: Grant
    Filed: January 23, 2008
    Date of Patent: June 4, 2013
    Assignee: Etex Corporation
    Inventors: Aron D. Rosenberg, Laurent D. Gilles de Pelichy, Daniel Egan, Aliassghar N. Tofighi, Youngmi M. Lee
  • Delayed-setting calcium phosphate pastes
    Patent number: 8216359
    Abstract: The invention features delayed-setting calcium phosphate pastes which are useful for the preparation of delivery vehicles for biologically active agents, useful for the treatment of orthopedic conditions and can be stored for long periods without prematurely setting.
