After further review of additional information received the following sections have been updated accordingly: d2, g1, g3, g6, h1, h2, h3 and h6.As reported, a piece of an 8f brite tip 23cm str sheath broke off during removal and remained in the patient.The device was flushed prior to use.The vessel dilator was snapped into place at the hub.There were no difficulties encountered during the insertion process.There were no damages noted to the device prior to using it.The patient was stable and discharged.The vessel at the insertion site was not noted as a difficult site according to the physician operation (op) note.The distal portion, black end that is radiopaque broke off into the patient.There was no attempt to remove the piece that broke off.A non- sterile ¿si brite tip 8f 23cm str" catheter sheath introducer (csi) was received for analysis.The only returned component was the brite tip sheath introducer.During visual inspection, a torn and separated condition was noted on the distal tip.Inner diameter (id) and outer diameter (od) measurements were taken near the damages and were found within specification.Sem analysis was not performed because the damages associated with the torn and separated area is visible with the magnification obtained with a vision system.Magnified images of the damaged edges presented evidence of elongations and plastic deformation with a path directed from the distal edge toward the proximal area.An axial section of the distal tip is separated.The missing section of brite tip was not returned for analysis.A product history record (phr) review of lot 18134729 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 ¿brite tip/distal tip ~ separated¿ was confirmed, a section of the brite tip/distal tip was separated.The elongations and plastic deformation found on the material are commonly associated with damages caused by exposure to a sharp object, which exceeds the material yield strength.Therefore, it is assumed that the distal tip was induced to a tensile force that exceeded the material yield strength prior to the separation.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, ¿do not use if package is open or damaged.If increased resistance is felt upon insertion of the csi, investigate the cause before continuing.If the cause of the resistance cannot be determined and corrected, discontinue the procedure and withdraw the csi.¿ based on the phr review and the available information, there is no indication that the event is related to the device design or manufacturing process.Therefore, no preventative or corrective actions will be taken at this time.
