Hi, looking around Yt I've found Dave's video about a nice box that translates current to mV similar to a regular shunt.
Video link:
The question is does anyone know the name of the device at 17:40?

Do you mean the uCurrent?
Details in the EEVBlog store, but currently out of stock.

It is a device that Dave Jones designed and sells. He calls it "microcurrent". It is a shunt plus an amplifier to increase the small voltage developed across the shunt.

Dave published an article describing it, so you could actually build your own if so inclined.
http://eevblog.com/files/uCurrentArticle.pdf
There is a few videos and forum posts about improvements (the uCurrent "Gold", potential issues, and custom mods) since that article was originally published.
The EEVblog 121GW DMM also includes a similar amplifier for "low burden" current measurement.

If you want something pre-made and don't mind paying a bit for it, there is the CurrentRanger:
