Event Description

It was reported that a patient underwent an atrial fibrillation (afib) procedure with a lasso® nav eco variable catheter.Immediately after insertion, became inoperability at the timing when decreased the ring diameter immediately.The issue was resolved by replacing the lasso® nav eco variable catheter.Patient was unaffected.The procedure was completed without patient's consequence.Additional information was received.There was some resistance.There was no ring, electrode or other physical damage observed at the distal end of the catheter.

Manufacturer Narrative

Manufacturer Narrative

It was reported that a patient underwent an atrial fibrillation (afib) procedure with a lasso® nav eco variable catheter.Immediately after insertion, became inoperability at the timing when decreased the ring diameter immediately.The issue was resolved by replacing the lasso® nav eco variable catheter.Patient was unaffected.The procedure was completed without patient's consequence.Additional information was received.There was some resistance.There was no ring, electrode or other physical damage observed at the distal end of the catheter.The investigation was completed on 08-may-2024.The device was returned to biosense webster (bwi) for evaluation.Visual inspection and deflection test of the returned device were performed following bwi procedures.Visual analysis revealed no damage or anomalies on the device.A contraction test was performed, and it was observed that the mechanism was not contracting correctly.For this type of issue, a manufacturing meeting was performed and it was concluded that the puller wire of the contraction mechanism was broken.Since the process has control points to check the deflection and contraction, this complaint is not related to the manufacturing process.A manufacturing record evaluation was performed for the finished device batch number, and no internal actions were identified.The contraction issue reported by the customer was confirmed since a broken contraction puller was found during the meeting.The potential cause of the puller wire broken could be related to the excessive force during the usage of the device.The instructions for use (ifu) contain the following recommendations: always pull the thumb knob of the catheter back before insertion or withdrawal to assure that the catheter tip assumes its straight position.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).
