Event Description

On (b)(6) 2024, the patient underwent endovascular procedure using gore® excluder® aaa endoprostheses to treat an abdominal aortic aneurysm.The gore® dryseal flex introducer sheath (dsf1833/ 27266549) was used for access.Reportedly, the procedure was progressing as planned.After the full deployment of (b)(6), when the physician pulled the catheter out of the sheath, the olive tip was missing.Reportedly, the olive plus approx.3cm of the clear inner lumen was in distal end of the sheath near the valve.The olive tip was successfully removed with no harm to the patient.According to the physician, a tightness in the sheath at the valve caused the olive separation.Also, the physician felt a little difficulty at the valve on insertion but not excessive.The case was completed with patient stable condition.

Event Description

The physician felt a little difficulty at the valve on insertion but not excessive.It didn¿t appear that any unusual force was used on withdrawal.

Manufacturer Narrative

B5: description summary was updated.H.6.Code c19: a review of the manufacturing records for the device verified that the lot met all pre-release specifications.B6: imaging evaluation.C20: this code was used to cover that imaging was unable to provide an evaluation in relationship to this event.E2402 was used to cover that the procedure was completed with no harm to the patient.F26 was used to explain that the olive tip was successfully removed with no harm to the patient.B01: the device remains implanted, however, the delivery catheter was provided for the engineering analysis.C24: the delivery catheter was provided to gore for engineering evaluation.The device evaluation showed the following: visual inspection of the returned components confirmed that the leading end of the catheter with the attached leading olive had separated from the rest of the delivery catheter and was not returned for evaluation.The returned portion of the delivery catheter appeared to be intact with no signs of fracture or breakage.The mid olive and shrink tube appeared to be intact with no signs of fracture or breakage.Additionally, the blue polyimide was not visible through the mid olive.Based on the findings of this evaluation, the physician¿s observation that ¿when the physician pulled the catheter out of the sheath, the olive tip was missing¿ could be confirmed.Based on the findings of this evaluation, the physician¿s observation that ¿a tightness in the sheath at the valve caused the olive separation¿ could not be confirmed with the available information.The likely cause for the separation of the leading end of the catheter from the delivery catheter could not be determined with the available information.This type of occurrence will continue to be monitored.According to the gore® excluder® aaa endoprosthesis instructions for use (ifu) warning: do not continue advancing any portion of the delivery system if resistance is felt during advancement of the guidewire, sheath, or catheter.Stop and assess the cause of resistance.Vessel or catheter damage or premature deployment have occurred and may result in potential patient harms.Do not continue to withdraw the delivery catheter if resistance is felt during removal through the introducer sheath.Forcibly withdrawing the delivery catheter through the introducer sheath when resistance is encountered has resulted in adverse events including catheter breakage or separation resulting in potential patient harms.If catheter separation occurs, use best medical judgment to determine the appropriate course of action for the patient.Effective removal of the catheter component has been reported through both surgical (e.G.Cut down) and endovascular techniques (e.G.Snaring, sheath removal).
