No...coated catheters do NOT emit silver ions while the AgION catheter
DO.

You assume ALL infections of catheters are started from outside the
host. Not always.

This sentence is crap...Is "the antibiotic" your talking about silver
ions? Do they only work on the catheter then become useless?

Semantics huh.
Regardless of how you phrase it the new AgION catheters "lead to a
marked reduction in catheter-associated infections of the bloodstream."
Other silver coated cathters do NOT have this overall systemic effect
from what I've read. Whats the difference? Perhaps this...
"Over a period of one year, silver ions are released slowly from the
catheter's inner and outer surfaces" which leads to a "marked reduction
in catheter-associated infections of the bloodstream."

Not to say coated catheters are worthless, they just don't work as well
and again they are not the same...
CONCLUSIONS: The risk of infection declined by 21% among study wards
randomized to silver-coated catheters and by 32% among patients in whom
silver-coated catheters were used on the wards. Use of the more
expensive silver-coated catheter appeared to offer cost savings by
preventing excess hospital costs from nosocomial UTI associated with
catheter use. Arch Intern Med. 2000;160:3294-3298.
