Misplaced Renuva: how to remove immediately?

I had Renuva injected 24 hours ago, and it was immediately clear that it's in the wrong place. My surgeon tried to remove it, but none came out. Can this be removed by flushing it with saline? Any other methods? More background: I was trying to fill an indentation in my hip crease that appeared after liposuction. Instead of filling the indentation, it made it look worse—it created an even higher raised edge around the "rim" of the indentation.
