    摘要： A system and method for retrieving an implantable device includes a delivery catheter, a recapture section, and a sheath. The delivery catheter has a proximal end and a distal end. The recapture section is axially extendable from the distal end of the delivery catheter. The sheath has a proximal end and a distal end and a lumen sized to receive the delivery catheter. A portion of the lumen of the sheath is actuatable from an enlarged inside diameter to a reduced inside diameter to apply an inwardly directed force to the recapture section. The delivery catheter can be actuated with respect to the sheath to extend or retract the recapture section with respect to the delivery catheter.

    摘要： The present disclosure provides a transformer comprising, a transformer core and a tank portion arranged to contain a cooling fluid for absorbing thermal energy from the transformer core. The transformer also comprises a radiator portion which is in fluidal communication with the tank portion and for radiation of at least a portion of the thermal energy absorbed by the cooling fluid. A first temperature sensor is arranged to provide an output that is dependent on a local temperature at the radiator portion. A second temperature sensor is arranged to provide an output that is dependent on a local temperature at another portion of the transformer. The transformer is arranged so that the outputs of the first and second temperature sensors relative to each other are indicative of a level of the cooling fluid or are indicative of a thermal property different from that expected given a power being transformed by the transformer.

    摘要： An aluminum silicon die cast alloy having a very low iron content and relatively high strontium content that prevents soldering to dies into die casting process. The alloys of the present invention also have a modified eutectic silicon and modified iron morphology, when iron is present, resulting in low microporosity and high impact properties. The alloy comprises 6-22% by weight silicon, 0.05 to 0.20% by weight strontium and the balance aluminum. Preferably, the alloy of the present invention contains in weight percent: 6-20% silicon, 0.05-0.10% strontium, 0.40% maximum iron and most preferably 0.20% maximum iron, 4.5% maximum copper, 0.50% maximum manganese, 0.60% maximum magnesium, 3.0% maximum zinc, balance aluminum. On cooling from the solution temperature, the strontium serves to modify the eutectic silicon structure as well as create an iron phase morphology change if iron is present, facilitating feeding through the aluminum interdendritic matrix. This, in turn, creates a finished die cast product with extremely low levels of microporosity defects. The strontium content also appears to create a non-wetting monolayer of strontium atoms on the surface of a molten casting, preventing die soldering, even at very low iron contents. The alloy may be used to cast any type of object and is particularly suited for casting outboard marine propellers, driveshaft housings, gear case housings, Gimbel rings and engine blocks.
