It was reported that a patient underwent a redo atrial fibrillation cardiac ablation procedure with a thermocool® smart touch¿ electrophysiology catheter and there was no irrigation through ablation catheter and broken flex.It occurred after the device was used on the patient.Ablation was already performed before the issue started.They tried to flush both with the pump and with a syringe directly on the catheter, however, it was impossible to get water through the catheter.When the catheter was replaced, the issue was resolved.There was no patient consequence.Device evaluation details: the device was returned to biosense webster (bwi) for evaluation.A visual and x-ray inspections, deflection and irrigation tests of the returned device were performed in accordance with bwi procedures.Visual analysis revealed no damage or anomalies on the device.The device failed the flow pump test as high-pressure values were observed.A deflection test was performed, and the device failed to meet the curve specifications.An x-ray inspection was performed, and the puller wire was observed loose at the handle area.A manufacturing investigation was initiated, and it was found that the puller wire was entangled with the other components of the device including the irrigation tube due to an omission of the process.An awareness session was performed for all the personnel involved.A manufacturing record evaluation was performed for the finished device number lot 31132338m and no internal action related to the complaint was found during the review.The irrigation and deflection issues reported by the customer were confirmed.The instructions for use contain the following recommendations: flush the catheter with heparinized saline prior to insertion into the body.Do not manually pre-shape the distal shaft of the catheter by applying external forces intended to bend or affect the intended shape or curve of the catheter.Always maintain a constant heparinized normal saline infusion to prevent coagulation within the lumen of the catheter.Do not use the catheter without irrigation flow.This product issue will be addressed through bwi's quality system.If additional information is received regarding this event, a supplemental 3500a report will be submitted to the fda.Manufacturer's reference number: (b)(4).
