Manufacturer Narrative

No device was received for analysis at the time of submission of the initial 3500a.Since the product was not returned for analysis, no product failure analysis can be conducted and no determination of possible contributing factors could be made.The device history record (dhr) for the lot number 17763237m has been reviewed and it was verified that the device was manufactured in accordance with documented specifications and procedures.Biosense webster manufacturer's reference number (b)(4) has two complaints that are related to the same incident.Manufacturer's ref.No: (b)(4).

Event Description

It was reported that a patient underwent an atrial flutter left (l-afl) procedure with a webster¿ electrophysiology catheter.It was reported that the catheter was not deflecting properly due to a defective puller wire.It was also reported that some of the insulation of the catheter was exposed.The catheter was replaced and the deflection issue remained.The catheter was replaced again and the issue resolved.No patient consequence was reported.The response received confirmed that the physician reported that he rubbed with his gloved finger an electrode ring on both catheters and felt sharp edges.The issue was observed prior to insertion into the body upon removal from sterile package.It was also confirmed that the insulation exposed was observed proximal to the distal pair of electrodes.The catheter was not pre-shaped.The deflection issue was assessed as not reportable.Since the catheter is unable to deflect or relax completely, the user will not be able to use the device and will have to replace it.The potential risk that it could cause or contribute to a death or serious deterioration in state of health was remote.The sharp ring edges and insulation exposed issues were both assessed as reportable malfunctions on both the webster¿ electrophysiology catheter¿s.
