Additional information and correction: it was reported that a patient undergoing cardiovascular surgery had a swan ganz catheter placed via left internal jugular vein.The balloon tested normally pre-insertion.Upon insertion, the customer had difficulty advancing the catheter.After multiple attempts, the customer pulled the plunger of the inflation syringe and blood was aspirated.The catheter was removed from the patient with a balloon rupture being noted.The customer thought the rupture of the balloon was from when the catheter was removed.No patient complications were reported.One catheter with attached monoject 1.5 cc limited volume syringe and 3 three-way stop cocks was returned for evaluation.No introducer or packaging was returned.Customer report of ¿balloon rupture¿ was confirmed.As received a kink was observed at 11cm to 12cm from the catheter tip.Blood was confirmed in the attached monoject syringe as received in the decontamination lab.Balloon inflation lumen was occluded.Catheter body was kinked at 11 cm, 12 cm, and 86 cm proximal from the catheter tip.Balloon was found to be ruptured around the central area of the balloon latex and the central area of the balloon latex was missing.All through lumens were patent without any leakage or occlusion.No visible damage to the returned syringe was observed.Further examination confirmed balloon rupture and the inflation lumen was found fully occluded with blood.The occlusion was not able to be cleared.An examination of the catheter body was performed at 10x magnification and no punctures or tears to the catheter body with the exception of the 3 kinks were observed.The thermal filament cover was found to be loose indicating some stretch to the catheter body.The catheter passed freely through a 9f introflex introducer which is the required size per the ifu.Balloon inflation test was performed using returned syringe with 1.5 cc air.Visual examinations were performed under microscope at 20x magnification and with the unaided eyes.The customer report was confirmed.An investigation has been initiated to consider any potential manufacturing factors that may have contributed to this complaint and implement any necessary corrective actions.
