Our product lab received one model 777f8 swan-ganz catheter with an attached monoject limited volume syringe.The balloon inflated clear and concentric, and remained inflated for 5 timed minutes without leakage.No visible damage or deterioration was found from the balloon latex and balloon bonding sites.The balloon deflated within 2 seconds without the syringe, which was within specification for the maximum deflation time from full capacity.The ifu states to passively deflate the balloon by removing the syringe from the gate valve.All through lumens were patent without leakage or any sign of occlusion.No visible damage was observed from the catheter body.The customer report of balloon would not deflate was not able to be confirmed on evaluation.An engineering evaluation has been initiated to assess for any manufacturing-related processes which could be correlated to the complaint.
