An event took place while treating the last fraction (fx3) of a multi-catheter breast implant with 14 catheters.The dummy sequence took place without any errors or faults, and the video camera was zoomed in on the catheters.We visually confirmed that the dummy wire entered the correct catheter each time, which is the typical practice.After the dummy sequence ended, we zoomed out the camera, so we can see and monitor the patient.The treatment took place uneventfully until catheter no.9, when the patient reported by voice that something touched her.We immediately stopped the treatment and zoomed in.At that time the wire was outside of patient's body hanging over the neck by about 10cm.After entering the room, we inspected catheter no.9 and it was connected properly, as all the others.Was only after disconnecting the quick connect, that we discovered what happened: the plastic catheter kinked and the wire managed to push through, puncturing the catheter.
