I have used these, or ones like these for GAR on the Chattahoochee.
it is basically frayed nylon rope tied onto short a steel leader. No hook, the teeth get caught in the rope.
I have a mouth spreader that I use to hold the mouth open and remove the rope from the teeth with my forceps. the lure usually last for one fishing trip or about 3 – 4 fish.

Hope this helps, share some pics.
