Abstract: Catheters are described that have improved flow characteristics that may be particularly helpful when delivering embolic agents within a blood vessel. One catheter includes a fluid flow modifier that is configured to create laminar fluid flow out of a distal end of the catheter to help reduce turbulence and achieve predictable fluid movement. Another catheter includes scavenging ports that are configured to suction in embolic agents that have refluxed proximally back from a distal end of the catheter.

Abstract: A vascular occlusion device for occluding blood flow in vasculatures having higher blood pressure or increased rates of blood flow. The vascular occlusive device may include a support frame for withstanding the higher blood pressure or increased flow rates. The support frame may include a central portion, a distal support arm extending in a distal direction from the ring portion, and a proximal support arm extending in a proximal direction from the ring portion. In one embodiment, the distal support arm may include one or more distal hinges and the proximal support arm may include one or more proximal hinges. In another embodiment, the distal and proximal support arms may each include a helical coil.

Abstract: In some examples, a catheter includes an elongated body comprising proximal and distal portions. The distal portion of the elongated body comprises an inner liner that includes a proximal liner section and a distal liner section that include different materials, and an outer jacket positioned over the inner liner. The distal liner section has a first hardness and the proximal liner section has a second hardness, where the first hardness is less than the second hardness.

Abstract: A wireless precision avionics kit is provided for retrofitting aircraft to facilitate communication between the cockpit and modern military stores without hardware or software modifications to the aircraft. The store includes an electrical interface that requires data and possibly power from the aircraft and provides for communication via a message set. The kit may be used with any aircraft that provides a rack or pylon for mounting the store and the capability to release the store. The kit may be used with aircraft having no existing capability to communicate with smart stores, with aircraft having an incompatible interface for modern stores or even with aircraft that have a compatible hardware interface for which the software is outdated.

Abstract: A pill container has a casing with a closed end, an open end, and a chamber. The chamber can hold the pills and communicate with the open end. A cap having an inside surface can releasably attach to the open end and close the casing. A pin is centrally secured at the inside surface of the cap. This pin is positioned to extend into the chamber of the casing when the cap is attached to the casing. A plunger is slidably mounted in the chamber of the casing. A spring mounted in the casing can urge the plunger toward the open end of the casing to hold the pills in position, so that agitation would not tend to powder the pills.
