Although the proximal portion of circular catheter was snared, we could not retrieve the broken catheter, because the snare slipped up as soon as we tried to pull the assembly. (Figure 1A). The distal portion was held by another loop snare (Figure 1B). Fortunately, our attempt was successful this time (Figure 1C).
