The product investigation was completed.Device evaluation details: the device was returned to biosense webster (bwi) for evaluation.Visual inspection and temperature and impedance test of the returned device were performed following bwi procedures.Visual analysis revealed that electrode 2 was lifted with sharp edges and internal components exposed.The damage observed could be related to the manipulation of the device during the procedure; however, this cannot be conclusively determined.No other damage was observed.The temperature and impedance test was performed and the device was found working correctly.No temperature or impedance issues were observed.The damage observed could be related to the manipulation of the device during the procedure; however, this cannot be conclusively determined.A manufacturing record evaluation was performed for the finished device [(b)(6)] number, and no internal actions related to the reported complaint condition were identified.The temperature issue reported by the customer could not be replicated during the product investigation; other issues or circumstances may have occurred during the usage of the device that compromised its performance.The instructions for use contain the following recommendations: if the radiofrequency (rf) generator does not display temperature, verify that the appropriate cable is plugged into the rf generator.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).

It was reported that a patient underwent a right-sided atrial tachycardia (at-right) cardiac ablation procedure with a thermocool® smart touch¿ bi-directional navigation catheter and post procedure the bwi product analysis lab identified that electrode 2 was lifted with sharp edges and internal components exposed.During the procedure, the medical team noticed that the temperature showing error on ablation.The error indicated that the temperature was low.When the medical team tried to switch off the pump and rf (radiofrequency) generator, the issue persisted.The temperature issue continued after a cable change too.The catheter was changed and the procedure continued.
