Complaint conclusion: during an unknown procedure, when advancing the guidewire into a 4f infiniti (110cm 6sh) pigtail catheter, the pigtail end broke off.There was no reported patient injury.Multiple attempts to gather additional information were unsuccessful.The device was not returned for analysis.A product history record (phr) review of lot 17581813 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The phr review does not suggest that the event reported by the customer could be related to the manufacturing process.The reported ¿ brite tip/distal tip ¿ catheters separated¿ could not be confirmed as the device was not returned for analysis and procedural films/device photographs were not received.It is difficult to draw a clinical conclusion between the device and the event based on the limited information available.However, procedural and handling factors may have contributed to the reported event.Per the instructions for use, which is not intended as a mitigation, ¿exposure to temperatures above 54c (130f) may damage the catheter.To prevent damage to the catheter tip during removal from the package, grasp the hub and withdraw the catheter.Exercise care when removing guidewires from multiple-curve catheters.To prevent kinking of 5f (1.65 mm) and smaller angiographic catheters, and specifically the 4f (1.35 mm) infiniti® pigtail catheters: straighten the pigtail catheter tip only with a diagnostic guidewire or, if applicable, with a tip straightener.Do not straighten by hand.Use a guidewire when introducing the catheter through the catheter sheath introducer (csi) and into the left ventricle.Treat all 4f (1.35 mm) catheters and smaller french sizes with ultimate care.The performance of these products may be impaired if not properly and cautiously handled during unpacking and preparation.¿ neither the phr review nor the available information suggest that the reported event could be related to the manufacturing process.Therefore, no corrective or preventive actions will be taken.
