The product investigation was completed.Device evaluation details: the device was returned to biosense webster (bwi) for evaluation.A visual inspection, the temperature and impedance test, cool flow pump and pressure gage test, and magnetic sensor functionality test of the returned device were performed following bwi procedures.Visual analysis revealed a hole in the pebax and foreign reddish material was observed inside it.The device was connected to the carto 3 system and it was recognized and visualized correctly.No issues or errors were observed.The temperature and impedance test was performed and the device was found working correctly.No temperature or impedance issues were observed.Also a cool flow pump and pressure gage test was performed, and the device was irrigating correctly.No irrigation issues were observed.A manufacturing record evaluation was performed for the finished device lot number 30903191m, and no internal actions related to the reported complaint condition were identified.The reddish material inside the pebax could be related to the temperature and ablation issue reported by the customer; therefore, all issues reported were confirmed.The root cause of the pebax damage could be related to the manipulation of the device during the procedure; however, this cannot be conclusively determined.It should be noted that product failure is multifactorial.The instructions for use contain the following recommendations: the force sensor of the catheter is disconnected.If the problem persists, replace the catheter cable or the catheter.As part of biosense webster's quality process, all devices are manufactured, inspected, and released to approved specifications.If additional information is received regarding this event, a supplemental 3500a report will be submitted to the fda.Manufacturer's reference number: (b)(4).
