We have received the complaint device for evaluation.However, we were unable to replicate the reported incident.When we attempted to deflate the balloon of the distal perfusion catheter after inflating it with saline to a recommended volume of 3.4 ml, we were able to properly deflate the balloon.We attempted to recreate the defect multiple times by inflating the balloon with different volumes of saline.However, we were unable to replicate the reported defect as the balloon deflated properly each time.Hence, we could not determine the cause of the failure as the device worked properly during our evaluation process.Our review of the lot history records for this lot did not find any discrepancies either in the manufacturing or packaging process that could be related to this incident.Further, we have not received any other complaints of a similar nature for devices from this lot.This issue was detected during pre-use check.So, the patient was not exposed to this catheter.Procedure was completed using another distal perfusion catheter.

During pre-use check, after surgeon inflated the balloon of the distal perfusion catheter with saline, he experienced difficulty deflating the balloon.It either deflated only partially or took longer time to deflate completely.This malfunction was detected during pre-use check.So, the patient was not exposed to this catheter.
