As reported, the side of a 5f tempo berenstein (ber) 0.038in x 100cm diagnostic catheter ripped and twisted while in the patient's body.After insertion into the left femoral artery, the catheter ripped approximately midway from the tip.The catheter was safely removed from the patient.There was no reported patient injury.Four pictures related to the reported failure were submitted for review.Picture #1 shows the inner label of the product, and the following information can be read: lot# 18199504, catalogue# 451-513h0 and use by date 2026-03-31.Pictures #2,3 & 4 show the catheter coiled and a section is twisted.Bloody residue could be noticed.No other anomalies of the product were noted during the photo analysis.The reported ¿catheter (body/shaft)-puncture /cut¿ was not confirmed, however a twisted condition was observed.The root cause of the failure reported by the customer could not be conclusively determined as part of the picture evaluation however, excessive torquing is a likely cause.Users are trained to inspect for signs of damage prior to and during use.Any product with damage is not to be used.Information for safety is provided in the products labeling with the intent to make the user aware of the risks.According to the instructions for use (ifu), although not intended as a mitigation of risk, ¿to prevent kinking of 5f (1.65 mm) and smaller angiographic catheters, and specifically the 4f (1.35 mm) infiniti® pigtail catheters: 1.Straighten the pigtail catheter tip only with a diagnostic guidewire or, if applicable, with a tip straightener.Do not straighten by hand.2.Use a guidewire when introducing the catheter through the catheter sheath introducer (csi) and into the left ventricle.¿ based on the information available and the phr review, there is no indication that the event is related to the device design or manufacturing process.Therefore, no preventive or corrective actions will be taken at this time.
