A method and apparatus for automated display of documentation is disclosed. A problem concerning gas-evolution reactions is solved by eliminating chloride ions, sodium ions, and moisture contaminants. There is also provided a vacuum for removing the portions of the tampon applicator that are punched out. In one embodiment, the material that encapsulates the mechanical structures is, for example, silicon, silicon carbide, silicon-germanium, germanium, or gallium-arsenide. The invention further relates to a treatment programme for treating heart failure, which involves the co-use or co-administration of perhexiline with one or more other compounds that are advantageous in treating heart failure or the symptoms thereof.
