  • Patent number: 11432939
    Abstract: Various spinal implants and methods for stabilizing the spine are provided. In one exemplary embodiment, a spinal implant is provided having an expandable container with an interior volume that is selectively expandable between a compressed condition and an expanded condition. The expandable container is coupled to a superior endplate member having a bone-contacting surface and an engagement surface effective to mate with a superior surface of the expandable container, and an inferior endplate member having a bone-contacting surface and an engagement surface effective to mate with an inferior surface of the expandable container. In addition, at least one inlet port is formed in the expandable container and is effective to communicate a fluid to at least one cavity disposed within the interior volume of the expandable container.

  • Patent number: 9482351
    Abstract: The present invention relates to a process for the sterile transfer of fluids, be they liquids or gases. It uses a presterilized device comprised of a body having a bore formed through at least a portion of its interior. Contained within the bore is a movable plunger. The body has a first and a second end. The first end contains a face designed to be attached to the upstream component. The second end is connected to a downstream component such as a filter, pipeline, sample bag and the like. The plunger has corresponding first and second ends. The first end of the plunger when it the closed position is in alignment with the face of the body which combined form a steamable surface and a sterile barrier against the environment to the rest of the interior of the body, the plunger and downstream components. The device is attached to an upstream component and the face and the first end of the plunger are steam sterilized in place.

  • Patent number: 7137974
    Abstract: A sterile to sterile connection device comprising a connector and one or more coupling devices. The connector has body portion which has two openings sealed from the environment so as to form a sterile environment within the connector. At least one of the openings being sealed from the environment by a sterile barrier plug. The connector also has a port capable movement within the body of the connector to at least an open and a closed position. The coupling device is formed of a body having two openings and a stem having a bore through at least a portion of the stem. The stem is contained within the body and capable of moving at least linearly through the body between a first and second stem position. One of the openings of the stem is sealed from the environment by a sterile barrier plug and the other is sealed to a presterilized component. The coupling device opening containing the sterile barrier plug is attached to either the inlet or outlet of the connector.
