According to the complaint description, the white silicone sleeve detached from the guiding catheter when being pulled out and remained inside the cannula, requiring the cannula to be changed.The examination of the affected product could not be carried out as the product was not received due to contamination.However, the provided photo showed the silicone sleeve separated from the guiding catheter.Tracing lot 1100031252 (manufactured on 14.12.2023) showed no recurrence of this issue within the lot, suggesting that this may be an isolated incident.No batch-related issue could be identified.Based on the review of production documents and records of the incoming goods inspection of the affected parts, including tensile tests of the bonding between the silicone sleeve and guiding catheter, no particularities or deviations were found.This issue is currently being addressed within the initiated capa-000444 (corrective and preventive action).The investigation has not yet been completed, but it cannot be ruled out that a possible cause is associated with the bonding process.The bonding process is validated and controlled with in-process control measures.Batches that do not fulfill the acceptance criteria, including tensile tests, are discarded.However, it cannot be ruled out that in very rare individual cases the bonding or preparation steps before bonding were not carried out correctly.Nevertheless, it is difficult to definitively conclude what caused the problem in this case, as the affected product cannot be examined.

1) what went wrong with the device: after the tracheal cannula was placed without complications using the tracoe vario set, the guide catheter and wire were removed according to standard procedure.In the process, the conical "rubber stopper" apparently detached from the guide catheter and remained stuck in the tracheal cannula, making ventilation impossible.It was then no longer possible to thread the wire.The cannula had to be removed and a new tracoe vario cannula was inserted without wire guidance, which was successful.This resulted in an emergency situation.2) description of health effects: no harm to the patient.Reported.The patient survived.
