    摘要： An improved shell-and-tube steam instantaneous heat exchange system of a closely coupled feedback design which overheats water in the heat exchanger portion of the system and then blends the water, as needed, with proportional amounts of cold water to achieve the correct outlet temperature for a wide range of flow rates. The system uses at least two primary heat exchangers to provide redundancy in the case of failure of a major component of the system. Steam flow through the heat exchangers is controlled by the use of steam traps, rather than using a thermostatically controlled valve to vary the supply of steam. To obtain precise temperature control during varying water volume use, water is directed from the blended outlet of a first water tempering valve into the hot inlet port of a second water tempering valve. The first valve is designed to blend cold and hot water to a predetermined temperature which is higher than the second water tempering valve, so as to bias the second tempering valve, thereby minimizing thermal hunting and providing tighter temperature control from the second tempering valve.

    摘要： An expandable intravascular medical device is provided. The medical device comprises an expandable tubular body that includes an integrated resilient support structure that forms a plurality of electrically conductive regions to which the lead(s) is coupled. The tubular body further includes at least one electrically insulative element disposed between the conductive regions. In one embodiment, the support structure is skeletal in nature, e.g., it can be formed of a mesh, braid, or coil. The conductive regions can be variously formed by the support structure. For example, the support structure may comprise electrically conductive sub-structures that form the conductive regions. In this case, the sub-structures may be mechanically linked together by the insulative element(s), or they can be directly linked together, and the insulative element(s) can take the form of insulative layer(s) disposed on one or more of the conductive sub-structures. As another example, the support structure can have a conductive core and insulative material disposed over portions of the conductive core. In this case, the exposed core portions form the conductive regions, and the unexposed core portions form the insulative element(s).
