It is possible..I found this on Nerdist.com website.

This guy is called FloWarrior and has worked out a Sith Saber Throw system. He was at Edmonton Comic Con.
He is on Facebook if you can access it. He may be able to give advice.
I have also seen suggestions of using fishing line attached to a spring loaded cable retraction reel. Mount the retractable cable reel on your back (or back of your belt) and run the line down your arm and attach to your saber. You would need to experiment with line strength and spring settings but may be a way to go.
EDIT: I just managed to get on FB and found out this is the guy from the Behind the Scenes video (sorry) and the Levisticks are also known as Flow Wands.
