Can someone explain this briefly?

It looks to me like they basically have a ferrous material with low melting point. They drag chunks of it around using a magnet or magnetic field, then melt it with alternating magnetic field (AMF) heating.

The imprisoned Lego man was melted to get him through the bars, but he wasn't reconstructed afterward (which I'd hoped for given the "manipulation" portion of the abstract).

Is AMF heating compatible with body tissue? The bumpy edges and imprecise paths of the chunks they tease back out of the organ seem to me like that could cause damage to tissue?

Excited about the prospect and glad people are researching, but this didn't live up to my admittedly-futuristic anticipation.
