Manufacturer Narrative

Device investigation details: a picture was received for evaluation following biosense webster's procedures.According to pictures provided by the customer, a blood residue was observed on the tip of the catheter; however, no damages or anomalies were observed on the device.In the photo the anchor windows can be observed, and it looks like a hole; however, this component is part of the design of the device and no anomaly or damage on the device.The photo does not provided sufficient information related to the impedance issue reported by the customer and therefore no results can be obtained from it.A manufacturing record evaluation was performed, and no internal actions related to the reported complaint condition were identified.The customer complaint was not confirmed based on the picture received.The device has not been returned for analysis and a root cause is unable to be assigned based on the current evidence.If the device is received in the future, the product investigation will be performed and updated accordingly, and any action will be taken if necessary.E1.Initial reporter phone: (b)(6).If additional information is received regarding this event, a supplemental 3500a report will be submitted to the fda.Manufacturer's ref.(b)(4).

Event Description

It was reported that a patient underwent a cardiac ablation procedure with an ez steer¿ bi-directional electrophysiology catheter and a rupture in the catheter coating.The catheter caused an increase in impedance in radiofrequency (rf).When removing the catheter, it was observed that there was a rupture in the catheter coating.After the exchange, it worked normally.
