Abstract: A bidirectional intravascular blood pump system is disclosed for deployment in the descending aorta to improve perfusion in both upper and lower extremities. In some embodiments, the system includes a flexible stent housing containing an inflatable pump chamber and selectively inflatable proximal and distal check valves. In some embodiments, a controller sequences inflation and deflation of the pump components in coordination with the cardiac cycle. In some embodiments, the system capable of dynamically providing flow in opposite directions within the descending aorta to optimize systemic and cerebral perfusion. In some embodiments, the system can direct blood flow in either direction through the aorta by an inflation sequence of the check valves and pump chamber. In some embodiments, one or more bypasses in a check element, stent, and/or formed from selective inflation, enable pressurization of the aortic arch when timed with the closing of the aortic valve.

Abstract: Some embodiments of the disclosure are directed to a novel system for pumping liquid such as blood without damaging cells. In some embodiments, the system includes one or more inflatable elements such as balloons which force liquid from a heart assist pump. In some embodiments, one or more pumping elements are configured to directionally inflate. In some embodiments, the heart assist pump includes a reduced cross-section between two pumping elements. In some embodiments, the reduced cross-section is configured to enable the heart assist pump to be seated in the heart using the aortic valve. In some embodiments, the reduced cross-section gives the heart assist pump and hourglass shape, which allows a greater volume of fluid to be pumped through the aortic valve. In some embodiments, a controller independently controls fluid pumping elements on either side of the reduced cross-section.

Abstract: Some embodiments of the disclosure are directed to a novel system for pumping liquid such as blood without damaging cells. In some embodiments, the system includes one or more inflatable elements such as balloons which force liquid from an implanted pump. In some embodiments, one or more elements are configured to directionally inflate. In some embodiments, the directional inflation enables pumping in a bidirectional manner. In some embodiments, the system includes a plurality of elements that inflate sequentially to pump liquid in one direction or another. In some embodiments, the one or more elements are coupled to a tube or stent.

Abstract: A disposable dental instrument of the compressed air drive type is disclosed for use in performing dental procedures on a workpiece. The disposable dental instrument is constructed from two mating shells and a core. Each shell incorporates a mating surface and said shells are joined using various bonding methods to ensure a waterproof, high quality dental instrument. An elongated body has conduits penetrating a base at one end of the body. The conduits allow entry of a light beam, a pressurized water stream, and a compressed air stream into the body. The base includes attachment threads for securing the body to a source of the light beam, pressurized water stream, and compressed air stream. Pluralities of passageways are in communication with the conduits for conducting the light beam, the water stream, and the air stream through the body. A head at the opposite end of the body rotatably mounts a turbine shaft on bearing surfaces which inhibit vibration and noise.

Abstract: In some embodiments, a portable fluid dispenser is provided having a tank, a pump coupled to the tank for pumping fluid therefrom, and a battery connected to the tank for powering the pump. The battery can be part of a removable battery pack received within an external receptacle of the tank. Some embodiments of the dispenser are adapted to be worn (such as in the form of a backpack), while others are adapted to be carried by a user. Also, in some embodiments a conduit extends through the tank in order to enable fluid to pass from the pump to another location with respect to the tank.

Abstract: Apparatus for holding any one of a plurality of differently configured pumps to facilitate use of such pumps, for example, in dispensing beverages. The apparatus includes a housing and a plurality of different sets of elements located on the housing. Each different set of elements is adapted to at least assist in holding one of a plurality of differently configured pumps to the housing. The apparatus can be linked together to very effectively and conveniently provide for the management and maintenance of a relatively large number of pumps, being used in dispensing a correspondingly relatively large number of beverages.

Abstract: A mounting block for use with a beverage dispenser system having a pump and a pump accessory. The mounting block includes a frame and a manifold. The manifold includes a number of ports and a line connecting the ports, such that the pump and the pump accessory can plug into the ports for fluid flow therebetween via the line.
