In 2274, two gnomes armed with bolas beamed aboard the USS Enterprise, appearing to ride atop bats. One bola smashed the transparent aluminum shield between the pad and the console. A security guard remarked that the bola must be made of neutronium. (TOS comic: "There's No Space Like Gnomes'!")
In 2373, Colonel-Mayor Asta-ha invented a two-shot automatic bola pistol. It resembled a crossbow but with two launchers. Each fired one half of a small metal ball, each connected by a cable two meters long. When fired, the balls spread out and rotated, allowing the cable to stretch, spin and wrap around the target. It was one of several low-tech weapons Benjamin Sisko, Miles O'Brien and others developed to try to repel a Cardassian attack on the planet home of the Natives in the Stirnis star system.
