Abstract: A catheter pump is disclosed herein. The catheter pump can include a catheter assembly that comprises a drive shaft and an impeller coupled to a distal end of the drive shaft. A driven assembly can be coupled to a proximal end of the drive shaft within a driven assembly housing. The catheter pump can also include a drive system that comprises a motor and a drive magnet coupled to an output shaft of the motor. The drive system can include a drive assembly housing having at least one magnet therein. Further, a securement device can be configured to prevent disengagement of the driven assembly housing from the drive assembly housing during operation of the pump.

Abstract: Flares include grain assemblies comprising a combustible grain and a reactive foil positioned at least proximate to the grain and configured to ignite combustion of the grain upon ignition of the reactive foil. The reactive foil may include alternating layers of reactive materials. Methods of fabricating flares include at least partially covering an exterior surface of a combustible grain with a reactive foil to form a grain assembly, and inserting the grain assembly at least partially into a casing. The reactive foil may include alternating layers of reactive materials that are configured to react with one another in an exothermic chemical reaction upon ignition. Furthermore, methods of igniting a flare grain include initiating an exothermic chemical reaction between alternating layers of reactive materials in a reactive foil located proximate to the flare grain.

Abstract: In this method for making a sintered reactive material, fuel particles are blended with a polymer matrix comprising at least one fluoropolymer in an inert organic media to disperse the fuel particles in the polymer matrix and form a reactive material. The reactive material is dried and pressed to obtain a shaped preform, which is sintered in an inert atmosphere to form the sintered reactive material. By sintering in an inert atmosphere, the sintered reactive material may include reactive metals and/or metalloids in a nonoxidized state. The resulting sintered reactive material preferably has a tensile strength in excess of 1800 psi and an elongation at break in excess of 30%.
