hi, i signed in today as i saw your comments on , catheters and iv's for aquapheresis, I'm in new zealand and we don't do this procedure, I bought a aquadex flexflow from usa, doctors here won't use it so I HAVE MY GRANDSON wanting to do the procedure, he doesn't want me passing without us trying. fluid retention is what I have, and have no other way to relieve it. we are learning as much as we can as we have no experience other then a possibility.
