As reported, the super torque catheter cath f5.2+ pig 145 degree 110cm 6sh was used and blood was oozing from what appears to be a small hole at the proximal end by the hub of the catheter shaft.There were no reported patient injuries.The catheter was removed from the packaging and flushed per usual practice.The procedure was completed successfully without adverse event.The device was stored in the cath lab hanging in the sterile pouch.The device was stored and handled per the instructions for use (ifu).There was no difficulty experienced in prepping the device.There were no anomalies noted to the device when it was taken out of the packaging.There were no difficulties removing the product from the packaging.The patient is currently doing well and was unaffected.A non-sterile cath f5.2+ pig 145 degree 110cm 6sh diagnostic catheter was received for analysis coiled inside a plastic bag.Per visual analysis, the external surface on the shaft of the unit presented a puncture hole at the proximal area of the catheter.No other anomalies were observed on the returned device.The unit was inspected under the vision system and the puncture hole was confirmed on the unit.The unit was sent for sem analysis to identify the cause of the observed puncture hole on the shaft.Sem analysis of the puncture hole result showed that the inner surface of the catheter presented neither damages nor anomalies.The outer surface of the catheter presented evidence of abrasion marks around the puncture hole.Also, a circular mark was observed around the puncture hole, as if a sharp object punctured the catheter from the outside to the inside of the catheter.The early mentioned damages observed on puncture holes are commonly caused during the interaction of the body/shaft with a sharp object or mechanical damage.It is assumed that the suggested sharp object punctured the catheter from the outside to the inside of the catheter due to the circular mark and abrasion mark observed on the outer surface.It is very likely that the same factors that caused the circular and abrasion marks on the outer surface could have probably led to the puncture hole condition found on the received body of the catheter.No other anomalies were found during the sem analysis.A product history record (phr) review of lot 17857390 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The complaint reported by the customer as ¿catheter (body/shaft)- puncture/cut - in-patient¿ was confirmed due to the puncture hole condition on the shaft of the unit as received.However, the exact cause of the puncture hole observed on the unit could not be conclusively determined during the analysis.The damages observed on the puncture holes are commonly caused during the interaction of the catheter body/shaft with a sharp object or mechanical damage.It is assumed that the suggested sharp object punctured the catheter from the outside to the inside of the catheter due to the circular mark and abrasion mark observed on the outer surface.It is very likely that the same factors that caused the circular and abrasion marks on the outer surface could have probably led to the puncture hole condition found on the received body of the catheter.According to the ifu, which is not intended as a mitigation of risk, ¿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: 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.Procedures requiring percutaneous catheter introduction should not be attempted by physicians unfamiliar with the possible complications.Complications may occur at any time during or after the procedure.¿ neither the phr review, nor the product analysis or the sem analysis results suggest that the failure could be related to the manufacturing process.Therefore, no corrective and preventive actions will be taken at this time.
