"Sensitive Bladder"

Bit of a euphemism that! Anyway, a couple of months ago there was an appeal on GN for women to trial an incontinence product, but I can't think of its name. I had read about it before ,and apparently it is given to French women. I received an email asking me to supply some more info, but I couldn't access the link. Did anyone else volunteer , and does anyone know what the thing is called please?
