I don't know how "new" it is. I have seen plenty of the spring kind - I
assume there's nothing magical about the spring other than by coiling it
that they get more surface area/wire in there instead of a straight
wire. I've seen slo-blos as both "springs" (I think "coils" is more
appropriate), and as as thick elements. I've seen thick elements for at
least 20 years now - not sure when they first started coming out, but I'm
sure it's been longer than that.
