Publication number: 20100145350Abstract: A bone filler delivery device includes a syringe assembly. The syringe assembly has a barrel with a first opening for dispensing bone filler and a second opening adapted to receive a plunger. A plunger is adapted to mate with the barrel to define a bone filler dispensing chamber therein. The plunger can move through the barrel in an axial direction. A seal is coupled to the plunger and is adapted to seal against the barrel. The seal includes an annular body and an annular first lip that extends from the body in a first direction and is adapted to flex toward the barrel when the plunger is moved through the barrel toward the first opening.Type: ApplicationFiled: February 12, 2010Publication date: June 10, 2010Applicant: Advanced Biomaterial Systems, Inc.Inventor: Roy B. Bogert

Publication number: 20090264891Abstract: A bone filler mixing and delivery device includes a mixing section adapted to mix components to form bone filler. A syringe barrel is coupled to the mixing section and has an opening through which the bone filler can be dispensed. A controllable portal can be manipulated to open a flow path between the mixing section and the syringe barrel. A plunger assembly is adapted to extend telescopically in an axial direction through the syringe barrel to dispense the bone filler through the opening.Type: ApplicationFiled: June 26, 2009Publication date: October 22, 2009Applicant: ADVANCED BIOMATERIAL SYSTEMS, INC.Inventors: Roy B. Bogert, James W. Nelson

Patent number: 7441943Abstract: Apparatus and methods for mixing and dispensing components. The methods and apparatus of the invention are particularly advantageous to manually mix the components of radiopaque bone cement and inject the resulting radiopaque bone cement into skeletal structures. The manually actuated apparatus of the invention comprises: (1) a sealed mixing chamber for mixing components; (2) a dispensing chamber isolated from the sealed mixing chamber; (3) a controllable portal to open a flow path between the sealed mixing chamber and the dispensing chamber so that the dispensing chamber can receive the mixed components after they are mixed; and (4) a drive mechanism associated with the dispensing chamber to force the mixed contents from the dispensing chamber.Type: GrantFiled: February 14, 2006Date of Patent: October 28, 2008Assignee: Advanced Biomaterial Systems, Inc.Inventors: Donald Barker, Roy B. Bogert, John P. Carr, James W. Nelson, Linda M. Trebing, Kenneth R Gleason, Damian Bianchi
