Hasn't happend to me, and hopefully won't. Deep breath, hold....it'll be okay...it'll be okay....
Can you try the vaccuum trick and string with a tiny ball of say cotton or something? Vaccuum the string through (prolly need to make a temporary nozzle modification) and then use the string to pull through oh I dunno pipe cleaners or something. Just a brainstorm... (although the diameter of the tube might prove tricky)
hope the wine is a-ok!
