Health- After living in E”Y for several years and having a relationship with someone in R’ Elyashiv Shlita’s inner circle, I -as well as Avi K and many others- have learned that you cannot believe with certainty anything that is said in his name. I have heard the same halacha question asked of him and once it was muttar and once assur (no special circumstances to speak of).
The famous joke that is said is someone asked R’ Elyashiv if twist ties can be used on Shabbos, and he said yes.
Someone else went into R’ Elyashiv and asked if twist ties can be used on Shabbos, and he said no.
?!?!?!
The answer is that the first guy motioned with his hand a single drey (twist) which is muttar, and the second guy dreyed twice which is assur.
Or for exmaple this story reported on YWN a couple of weeks ago:
