Device evaluation details: the product was returned to biosense webster for evaluation and the evaluation has been completed.Visual inspection and functional testing were conducted on the returned device.The visual analysis of the returned sample revealed that the thermocool® smart touch¿ electrophysiology catheter was received with a reddish material inside the pebax.A microscopic inspection revealed that the pebax has a hole on it.During the deflection test, it was noted that the catheter failed, as such, the catheter was dissected and it was found that the t-bar slid down from its place.Based on this finding, the customer complaint was confirmed.The evaluation determined that the blood inside the pebax area found could not be related to the reported issue.The root cause of the damage on pebax cannot be related to the manufacturing process since there is evidence that the device was manufactured in accordance with documented specification and procedures, it could be related to the handling of the device during the procedure, however, this cannot be conclusively determined.A manufacturing record evaluation was performed, and no internal actions were identified.As part of the biosense webster quality process, all devices are manufactured, inspected, and released to approved specifications.A deflection issue was observed during evaluation and the reported event was confirmed.The product instructions for use (ifu) contain the following recommendations: always pull the thumb knob back to straighten the catheter tip before insertion or withdrawal of the catheter.If additional information is received regarding this event, a supplemental 3500a report will be submitted to the fda.Initial reporter phone: (b)(6).Manufacturer's ref.# pc-(b)(4).

A patient underwent an atrial fibrillation (afib) ablation procedure with a thermocool® smart touch¿ electrophysiology catheter for which biosense webster¿s product analysis lab identified reddish material inside the pebax area and a hole in the pebax as well.It was initially reported that during the procedure, the catheter was unable to deflect or relax completely.A second catheter was used to complete the operation.There was no patient consequence.The customer¿s reported deflection issue was assessed as not mdr reportable since the most likely consequence is an intraprocedural delay and the potential risk that it could cause or contribute to a serious injury or death is remote.On 3/3/2021, the bwi product analysis lab received the complaint device for evaluation.On 3/10/2021, the complaint catheter was inspected and found with a reddish material inside the pebax and the pebax has a hole on it¿s surface.This finding of hole in the pebax has been assessed as an mdr reportable malfunction since the integrity of the device has been compromised.This event was originally considered non-reportable, however, bwi became aware of a reportable malfunction through product analysis on 3/10/2021 and reassessed it as mdr reportable.
