Our product evaluation lab received on model 831f75 swan-ganz catheter.The customer report of balloon ruptured was confirmed.As received, balloon was found ruptured.Balloon edges did not appeared to match at the rupture.Inflation lumen and distal lumen were occluded with blood.All other through lumens were patent without any leakage or occlusion.No other visible damage was observed from the catheter body or syringe.An engineering evaluation was performed to assess for any manufacturing related processes which could be correlated to the complaint.Based on the available information there is no evidence that supports or confirms the failure mode is associated to a manufacturing/ design defect.The ifu states to check balloon integrity by inflating it to the recommended volume.Check for major asymmetry and for leaks by submerging in sterile saline or water.Deflate balloon before insertion.The ifu also states that the duration of catheterization should be the minimum required by the patients clinical state since the risk of thromboembolic and infectious complications increases with time.The incidence of complications increases significantly with indwelling periods longer than 72 hours.A device history record review was completed and documented that device met all specifications upon distribution.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis and any excursions above the control limits are assessed and documented as a part of the monthly review.
