  • Patent number: 9549770
    Abstract: A device for storing and mixing bone cement components. The device includes a housing, a safety device, and a vacuum indicator. The housing defines a mixing chamber configured to store a first bone cement component therein. In a first safety position, the safety device prevents contact between the first bone cement component and a second bone cement component in the mixing chamber. In a second safety position, the safety device permits contact between the first and second bone cement components in the mixing chamber. The vacuum indicator restricts movement of the safety device from the first safety position to the second safety position when in a first vacuum indicator position. The vacuum indicator permits movement of the safety device from the first safety position to the second safety position when in a second vacuum indicator position.

  • Patent number: 9492947
    Abstract: A container for bone cement includes a first member defining a chamber, which contains a first ingredient. The chamber also includes a second member movably coupled to the first member. The second member includes a mixing device that is movably disposed within the first chamber, and the second member defines a second chamber containing a second ingredient. The container additional includes an opening device that selectively opens the second chamber and allows the second ingredient to enter from the second chamber into the first chamber. The mixing device is movable within the first chamber to promote mixing of the first ingredient and the second ingredient to prepare the bone cement. A corresponding method of preparing bone cement is also disclosed.

  • Patent number: 9060877
    Abstract: The present invention relates to an apparatus and method for near-simultaneous and integrated delivery of bone graft material during the placement of surgical cages or other medical implants in a patient's spine. The integrated fusion cage and graft delivery device according to various embodiments delivers and disperses biologic material through a fusion cage to a disc space and, without withdrawal from the surgical site, may selectably detach the fusion cage for deposit to the same disc space. The integrated fusion cage and graft delivery device is formed such that a hollow tube and plunger selectively and controllably place bone graft material and a fusion cage in or adjacent to the bone graft receiving area.
