As reported, while removing a 9f brite tip 35cm sheath introducer, it broke off in the patient.There was no reported patient injury.There was no lesion calcification.There was no vessel tortuosity.The vessel had moderate angulation.The device was not being used to treat chronic total occlusion (cto).The device was not resterilized.The shaft separated about 1cm from the hemostatic hub.No anomalies were noted when removed from the package.No anomalies were noted during prep.There was very minor resistance during the sheath removal when the device failed.There was not any resistance during the withdrawal of any devices through the sheath.There was a very minor amount of resistance prior to failure, it was within the expected amount of force to use when removing a sheath.The sheath may have been kinked or torqued prior to the separation, a figure eight hemostatic suture was placed prior to the removal of the sheath.The suture was tied, but not cinched down.The sheath was in place for 1.5 hours.An obturator was not used in the sheath after the procedure.The sheath was not used for any infusions.An attempt was made to cut down to the vessel and remove the device.It was unable to be identified within the vessel.A gooseneck snare was introduced via a 14f short sheath in the contralateral femoral vein.The sheath was snared in the mid portion and withdrawn through the venotomy.The site was then closed.

Complaint conclusion: as reported, while removing a 9f brite tip 35cm sheath introducer, it broke off in the patient.An attempt was made to cut down the vessel and remove the device; however, it was unable to be identified within the vessel.A gooseneck snare was introduced via a 14f short sheath in the contralateral femoral vein.The sheath was snared in the mid portion and withdrawn through the venotomy.The site was then closed.There was no reported patient injury.There was no lesion calcification.There was no vessel tortuosity.The vessel had moderate angulation.The device was not being used to treat chronic total occlusion (cto).The device was not resterilized.The shaft separated about 1cm from the hemostatic hub.No anomalies were noted when removed from the package.No anomalies were noted during prep.There was very minor resistance during the sheath removal when the device failed.There was not any resistance during the withdrawal of any devices through the sheath.There was a very minor amount of resistance prior to failure, it was within the expected amount of force to use when removing a sheath.The sheath may have been kinked or torqued prior to the separation, a figure eight hemostatic suture was placed prior to the removal of the sheath.The suture was tied, but not cinched down.The sheath was in place for 1.5 hours.An obturator was not used in the sheath after the procedure.The sheath was not used for any infusions.A non-sterile unit of product csi (si 9f brite tip 35cm) was received inside of a clear plastic bag.The product was removed from the plastic bag to do a first visual inspection without any optical magnifying device.A separation condition was observed on the csi cannula located at 33 cm from the distal end.The separated section was returned for analysis.Also, a kinked/bent condition was observed on the cannula at 20 cm from the distal end.No other damages or anomalies on the part was detected.The unit was placed under the microscope in order to obtain a magnified image of the separation area.Both ends of the separated sections presented evidence of elongations and frayed edges; also showing twisting conditions.These characteristics suggest that the device was induced to stretching/pulling or twisting events that exceed the material yield strength prior to the separation.No other issues were noted during microscopic analysis.Dimensional analysis was performed to verify the correct id and od of the cannula.Measurements were taken near the damaged areas and were verified to be within specification.A product history record (phr) review of lot 17821304 revealed no anomalies during the manufacturing and inspection processes that can be associated with the reported complaint.The reported ¿catheter sheath introducer - separated in patient¿ was confirmed through analysis of the returned device.However, the exact cause of the separation could not be determined during analysis.Based on the information available for review and product analysis, procedural/handling factors most likely contributed to the separation reported as evidenced by the evidence of elongations, frayed edges, and twisting condition.These characteristics suggest that the device was induced to stretching/pulling or twisting events that exceeded the material¿s yield strength prior to the separation.According to the instructions for use, which is not intended as a mitigation, ¿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.Thread the csi/dilator assembly over the guidewire, grasping the sheath close to the skin to prevent buckling.Using a rotating motion, advance the assembly through the tissue and into the vessel.¿ controls are in place to verify the device conditions; the produced csi are inspected 100% before leaving the facility.Neither the phr review nor the product analysis suggests that the reported failure could be related to the manufacturing process of the unit.Therefore, no corrective or preventive actions will be taken at this time.
