We have received the complaint device for investigation.When we inflated the balloon with saline, the balloon failed to inflate due to a pinhole in the balloon.The entire balloon was intact in the catheter without any signs of balloon fragmentation.Surgeon did not inspect the device prior to the procedure.Based on our investigation, it is possible that the balloon came in contact with calcified segment of the patient's vessel resulting in balloon rupture.We have sent a list of follow-up questions to the contact person at the hospital but we have not yet received a response.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.There was no harm to the patient as the result of this incident.Surgeon used another distal perfusion catheter to complete the procedure.
