An ablation device comprising an ablation applicator adapted for ablating material from an object upon delivery of an ablation medium to the ablation applicator in an ablation mode, an ablation medium supply line adapted for supplying the ablation medium to the ablation applicator in the ablation mode, an ablation medium drain line adapted for draining the ablation medium received from the ablation applicator in the ablation mode, and a closure mechanism adapted for selectively enclosing a predefined volume in a fluidic path upon operating the ablation device in a no-flow mode or upon detecting a leak in the fluidic path, the fluidic path including the ablation applicator and being defined between the ablation medium supply line and the ablation medium drain line.
