A delivery system is provided that includes a device having a body extending along a longitudinal axis between proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extends through the wall and includes a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a fluid within the proximal chamber out of the first port and the distal plunger moves a fluid within the distal chamber out of the second port to simultaneously actuate a bone filler dispenser. Systems and methods are also provided.

In a liquid material discharge apparatus, attachment/detachment of a liquid contact unit (2) and a main body unit (15) is more safely and easily performed. The apparatus includes the liquid contact unit (2) provided with a housing (6) including a nozzle (3) and a discharge member (5), and with a storage container (4) fluidly connected to the housing with the aid of a mounting member, and a main body unit provided with a holder (19) to which the housing is detachably attached, and with a drive unit (16) for actuating the discharge member that is detachably coupled to the drive unit, the apparatus further includes a movable member (12) being movable in an up-down direction along the housing while the movable member remains attached to the housing, and the discharge member and the drive unit are attachable with movement of the movable member in the up-down direction.

A compressible cartridge includes a first flexible bag, a second flexible bag, and a rigid face plate. The first and second flexible bags include a multilayer film having at least three layers formed from different materials. The first and second flexible bags have a front end and a sealed back end opposite the front end. The first flexible bag defines a first volume to receive a first flowable material. The second flexible bag defines a second volume to receive a second flowable material that is different from the first flowable material. The rigid face plate has a first collar, a second collar, and a nosepiece. The first collar is bonded to the front end of the first flexible bag, and the second collar is bonded to the front end of the second flexible bag. The nosepiece defines 1) a first opening that is in fluid communication with the first volume of the first flexible bag, 2) a second opening that is in fluid communication with the second volume of the second flexible bag, and 3) a discharge opening.

A common head for use in combination with a cartridge assembly, the cartridge assembly being retained within the material containment unit of a dispensing device and arranged to discharge reactive components from larger and smaller cartridges in response to actuation of the dispensing device. The common head includes inlet openings and a rigid walled tube having a partition positioned therein to define larger and smaller pathways to enable passage of the reactive components from the cartridges into and though the common head in a predetermined volumetric ratio and prevent backflow of the components which can lead to unintended curing prior to dispensing. A flexible liner arranged for positioning within one or both pathways of the rigid walled tube is also provided to prevent such backflow and unintended curing prior to dispensing.

A cartridge usable in a viscous-material dispenser includes a cylinder, a plunger in the cylinder, and a plurality of ribs extending radially from an outer surface of the plunger to an inner surface of the cylinder. The ribs are circumferentially separated by a plurality of clearances, and the ribs and the clearances extend in an axial direction. Each of the plurality of clearances is defined by two adjacent ribs. The ribs and clearances are configured to allow the venting of gas through the clearances during a beginning of a cartridge filling operation and to impede the movement of the viscous material through the clearances during a remainder of the cartridge filling operation such that, at an end of the cartridge filling operation, the ribs and bodies of the viscous material in the clearances form an airtight seal between the plunger and the cylinder.

A condiment dispensing device is provided that, when activated by a user, may expel a condiment from a condiment cartridge secured within the condiment dispensing device. The condiment dispensing device includes a recess at its bottom portion in which a dampener member may be secured. When the dampener member is secured in the recess, the bottom portion of the dispensing device is flat, which results in the device being orientation within a holder in a consistent and predictable fashion. Because the dampener member may be made of a rubber or soft plastic, when the condiment dispensing device is placed in the holder, substantially less impact and noise are created than if the dispensing device were construed entirely made of metal.
