Event Description
|
It was reported that a patient underwent an atrial fibrillation (afib) procedure with a qdot micro¿ catheter for which biosense webster¿s product analysis lab (pal) identified a hole on the pebax leaving internal parts exposed.During the procedure, when they were ablating, they were receiving temperature spike readings on the smartablate generator.To troubleshoot, the catheter was removed from the patient's body and they discovered char all over the catheter.Upon replacement of the catheter, they received error 105: magnetic sensor error.The catheter was replaced a second time and the issue seemed to be resolved.They were able to successfully ablate; however, upon finishing ablation and removing the catheter they noticed char all over this catheter as well.All three catheters used were from the same lot.There was no patient consequence reported.The biosense webster, inc.Product analysis lab received the device for evaluation and per the evaluation completion on (b)(6) 2023, there was a hole on the pebax leaving internal parts exposed observed.This event was originally considered non-reportable, however, bwi became aware of a hole on the pebax leaving internal parts exposed on (b)(6) 2023 and have assessed this returned condition as reportable.
