Abstract: A combination suction and irrigation device for a medical procedure. The device includes an elongated body having a proximal end and a distal end and defines an open channel that extends from the proximal end to the distal end. The open channel is open at both the proximal end and the distal end. A suction port is in communication with the open channel and is connectable to a source of suction. An irrigation port is in communication with the open channel and is connectable to a source of irrigation fluid. A valve selectively opens and closes the open channel to flow relative to the suction port and to the open proximal end, and to flow relative to the irrigation port.

Abstract: Disclosed are kits for preparing a reactive graft material and injecting the graft material into a patient. Kits may include a first syringe containing a first powdered component and a second syringe containing a second powdered component that is reactive with the first powdered component when the first and second powdered components are dispersed in a diluent solution. The kits may further include a vial sealed by a septum and containing the diluent solution. A syringe connector may be included that has a connector at each end configured to make a fluidic connection to, respectively, the first syringe and the second syringe, and also comprises a passageway adapted to allow fluid to pass between the syringes when the syringes are both fluidically connected to the syringe connector.

Abstract: The invention provides a particulate composition adapted for forming a bone graft substitute cement upon mixing with an aqueous solution, comprising i) a calcium sulfate hemihydrate powder, wherein the calcium sulfate hemihydrate is present at a concentration of at least about 50 weight percent based on the total weight of the particulate composition; ii) a monocalcium phosphate monohydrate powder; iii) a non-porous ?-tricalcium phosphate powder; and iv) a porous ?-tricalcium phosphate powder. Bone graft substitute cements made therefrom, a bone graft substitute kit comprising the particulate composition, methods of making and using the particulate composition, and articles made from the bone graft substitute cement are also provided.

Abstract: Methods and articles of manufacture for treating patients with degenerative bone are provided. The methods are useful to improve bone quality in a localized area of a degenerative bone (e.g., osteopenic or osteoporotic bone), such as by improving BMD to be substantially similar to BMD in an average, healthy individual at the age of peak BMD. The methods can comprise forming a void in a localized area of the degenerative bone and filling the void with a bone regenerative material that causes generation of new, healthy, natural bone material. The articles of manufacture can comprise kits formed of various materials useful in the inventive methods for improving bone quality.
