What's the weapon Nadia Fierro/Baldwin uses in Counterpart S01E08 to kill the guy in his flat?

In episode 8 of the first series of Counterpart, Nadia Fierro uses a kind of automatic strangling device, she puts it over the head of her victim, he struggles and dies. Is this original to the series or is it known from somewhere else? It is similar to the "bolito" from The Counselor, but not the same, as Counterpart's version doesn't seem to be electric.
