A bung, stopper or cork is a truncated cylindrical or conical closure to seal a container, such as a bottle, tube or barrel. Unlike a lid, which encloses a container from the outside without displacing the inner volume, a bung is partially inserted inside the container to act as a seal.

Apparatus and methods for sealing a vascular puncture
Apparatus for sealing a puncture communicating with a blood vessel includes a porous carrier formed from lyophilized hydrogel or other material. The plug may include at least first and second hydrogel precursors and a pH adjusting agent carried by the porous carrier in an unreactive state prior to exposure to an aqueous physiological environment. Once exposed to bodily fluids, the carrier expands as the lyophilized material hydrates to enhance and facilitate rapid hemostasis of the puncture. When the plug is placed into the puncture, the natural wetting of the plug by bodily fluids (e.g., blood) causes the first and second precursors to react and cross-link into an adhesive or “sticky” hydrogel that aids in retaining the plug in place within the puncture.

Degradable Material Assisted Diversion
Degradable material assisted diversion (DMAD) methods for well treatment, DMAD treatment fluids, and removable plugs for DMAD in downhole operations. A slurry of solid degradable material is injected into the well, a plug of the degradable material is formed, a downhole operation is performed around the plug diverter, and the plug is then degraded for removal. Degradation triggers can be temperature or chemical reactants, with optional accelerators or retarders to provide the desired timing for plug removal. In multilayer formation DMAD fracturing, the plug isolates a completed fracture while additional layers are sequentially fractured and plugged, and then the plugs are removed for flowback from the fractured layers. In DMAD fluids, an aqueous slurry can have a solids phase including a degradable material and a fluid phase including a viscoelastic surfactant. The solids phase can be a mixture of fibers and a particulate material.

Needleless valve
A needless valve is described which avoids the suctioning problems of the prior needleless devices upon deactivation and which preferably provides a positive self-purging effect. The valve is self-purging at the end of an administration cycle, avoiding clogging of attached catheters or other devices, and ensures that substantially all of liquid received into the valve is delivered to the receiver. The valve is also extremely simple in design and easy to construct and assemble, since it consists of only three pieces. The valve has a base with a connector for fluid communication attachment to tubing or other device, a solid elongated fluid channeling rod, and an internal fluid flow conduit; a flexible hollow expandable and contractible plug fitting over and moveable along the rod; and a tubular housing fitting over the plug and attached to the base. When the valve is activated by insertion of a nozzle of a fluid source, the rod and plug wall cooperate so that as the plug retracts along the rod, it is stretched and its interior expanded. Upon deactivation, the plug contracts, the interior volume decreases, and the resiling plug wall forces residual fliud within the valve to be expelled through the outlet, purging the residual fluid from the valve. No negative pressure is formed, so no suctioning of blood or other fluid from a patient or receiver occurs.

Multi-chamber, sequential dose dispensing syringe
A valve assembly is disclosed which effectively partitions a syringe into proximal and distal chambers to provide a multi-chamber, sequentially dispensing syringe apparatus. The valve assembly may be effectively used with a variety of standard, currently available commercial syringes and pre-filled syringes. Incorporated in the valve assembly is a valved stopper having a valve (which may be a slit valve), an impact sensor which opens the valve upon impact between the valve assembly and internal distal end of the syringe and a gas separator which separates liquid from gas disposed in the proximal chamber to assure gas is not delivered therefrom. The valve assembly is displaced as a plunger of the syringe is displaced via communication through fluid in the proximal chamber of the syringe. The actuator has a latching feature which latches the valve to an open state after being opened by the impact sensor. The gas separator has a proximally disposed orifice which facilitates priming. The valve assembly may be made from two parts. One part, a valved stopper, may be molded from the same rubber based material used in syringe plunger stoppers. The second part, the valve actuator, may be injection molded as a single part. A synthetic resinous material which is compatible with manufacture of living hinges my be used for the second part. Multiple valve assemblies may be used in a single syringe barrel.
