  • Patent number: 6159192
    Abstract: The present invention provides a method of connecting a reconstitution device to a drug container having a top and a closure. The method includes the steps of:providing a reconstitution device having first and second ends, the second end having a receiving chamber dimensioned to receive the top of the container for fixedly attaching the device to the container, the device having a central channel housing a piercing member, the device further having first and second sleeve members capable of sliding axially with respect to one another from an inactivated position where the piercing member is outside the receiving chamber to an activated position where a portion of the piercing member is positioned inside the receiving chamber; andinserting the top of the container into the receiving chamber of the device and fixedly attaching the container therein when the device is in the inactivated position.

  • Patent number: 6113583
    Abstract: A connector device is disclosed for establishing fluid communication between a diluent container having sidewalls and a drug vial. The connector has a piercing member having a first end and a second end and a central fluid pathway. The piercing member is mounted to the liquid container and has fluid accessing portions hermetically sealed from an outside environment. A vial receiving chamber is associated with the piercing member and is dimensioned to connect to the vial. The vial may be selectively attached to the device without piercing the closure of the vial and without breaching the hermetic seal of the fluid accessing portions of the piercing member. Means are provided for connecting the vial receiving chamber to the liquid container.

  • Patent number: 6090092
    Abstract: The present invention provides a connector device for establishing fluid communication between a first container and a second container. The device has a first sleeve member having a first end and a second end, the first sleeve member having at the first end a first attaching member adapted to attach to the first container; and a second sleeve member having a first end and a second end, the second sleeve member being associated with the first sleeve member and movable axially with respect thereto from an inactivated position to an activated position. A second attaching member is provided on the second end of the second sleeve and adapted to fixedly attach the second sleeve member to the second container. First and second piercing members are also provided projecting from one of the first and second sleeve members for providing a fluid flow path from the first container to the second container.

  • Patent number: 6019750
    Abstract: The present invention provides a septum for sealing an end of a medical connector. The connector has an end to attach to a closure of a container, the closure of the container having a target site, the connector further having a piercing member therein for piercing the target site of the closure. The septum comprises a disk having opposing first and second surfaces, a sheath extending axially from the first surface of the disk, and an annular ridge extending from the second surface of the disk, the annular ridge having a flared distal end, the distal end being dimensioned to form a fluid tight seal with the target area of the closure.

  • Patent number: 5989237
    Abstract: The present invention provides a connector device for establishing fluid communication between a first container and a second container. The device has a first sleeve member having a first end and a second end and a sidewall defining a chamber, the first sleeve member having at the first end a first attaching member adapted to attach to the first container. The device further has a second sleeve member having a first end and a second end, the second sleeve member being associated with the first sleeve member and is movable axially with respect thereto from an inactivated position to an activated position. A second attaching member is positioned on the second end of the second sleeve and adapted to attach the second sleeve member to the second container. A piercing member positioned in the chamber and projecting from one of the first and second sleeve members is provided for establishing a fluid flow path from the first container to the second container. The piercing member is hermetically sealed.
