Manufacturer Narrative

The referenced device was not returned to the manufacturer for evaluation.In addition, insufficient information was provided by the user facility.The exact cause of the reported event cannot be determined at this time.However, the manufacturer will continue to investigate the event and if additional information becomes available or if the device is returned at a later date, this report will be supplemented accordingly.As a preventive measure, the instruction manual provides warning that states, "visually inspect the instrument.Warped electrodes, defective insulation and broken, cracked, or irregular cutting loops represent a danger for both the patient and the surgeon and must not be used.Never try to bend irregular cutting loops into shape!" also, the instruction manual states, if any damage to the insulation at the electrode¿s distal end becomes visible during use, replace the electrode with an undamaged electrode.Otherwise there is a risk of injury for the patient and/or user.".

Event Description

The manufacturer was informed that during a therapeutic procedure, the middle piece of the cautery loop at the distal end of the electrode broke off and fell inside the patient's urinary bladder.The surgeon retrieved the device fragment by flushing/suction out with sterile water.There was no medical treatment required and there was no patient injury reported.

Manufacturer Narrative

To date, no device was returned for evaluation of the reported event.The original equipment manufacturer (oste) conducted a review of the device history records (dhr) as the manufacturing and quality control review was performed for the affected lot without showing any non-conformities or deviations regarding the described issue.

Manufacturer Narrative

The device was returned to the service center for evaluation of the reported ¿loop broke off¿.A visual inspection was performed on the device and damage to the distal end loop was confirmed as the distal end loop wire was broken off and missing.The two purple colored insulation tubing at the distal end was observed and noted some burn marks and the two posts were uneven and misaligned.The insertion portion was checked and noted the device was bent.There was no damage to the stabilization tube.A functional test could not be performed due to the condition of the loop wire.Based on the physical evaluation results and similar complaints related to hf electrodes, the potential cause for the damaged loop wire can be attributed to excessive stress from force applied to the device, operator's technique and/or the loop wire may have contacted with a metallic object during the hf output which can lead to damage of the loop wire.
