Additional Manufacturer Narrative
It was reported that a patient underwent a cardiac ablation procedure with an octaray mapping catheter, and an irrigation issue was observed.Device investigation details: the device was returned to johnson & johnson medtech (j&j medtech) for evaluation.Following j&j medtech procedures, a visual inspection and irrigation test of the returned device were performed.Visual inspection revealed no damage or anomalies on the device.An irrigation test was performed, and the catheter failed the test due to the irrigation tube being occluded in the tip area.Per the failure observed, a manufacturing investigation was performed.The issue was associated with material received from a supplier, specifically related to the subassembly that includes the irrigation tube.Manufacturing instructions establish the fixation points, as well as the requirement to ensure that the irrigation tube and wires remain free within the dual lumen¿s crescent area.Since the component is not free, it causes interference or entrapment of the irrigation tube and/or wires within the subassembly, which leads to the failure observed by the customer.A manufacturing record evaluation was performed for the finished device number lot, and no internal actions related to the complaint were found during the review.The irrigation issue reported by the customer was confirmed.The root cause is the manufacturing process, particularly the supplier for tip components.The instructions for use (ifu) contain the following information: flush the catheter with heparinized normal saline prior to insertion into the body and ensure that saline flows through the distal end of the irrigation lumen.As part of johnson & johnson medtech'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: pc-(b)(4).
