The reported event of resistance when removing catheter was confirmed due to balloon issue.As received, blood was observed inside gate valve and inflation lumen.It is difficult to inflate the balloon and balloon was also not fully deflated due to blood restriction inside inflation lumen.An interlumen leakage was found between inflation and proximal infusion lumens at the backform.Air leakage was observed from gate valve when the leak test was performed from proximal infusion lumen.Other through lumens were patent without any leakage or occlusion.No visible damage was observed from catheter body, balloon, and returned syringe.Further evaluation regarding related quality issues is under investigation.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.
