Event Description

It was reported that during a stent placement procedure in the right common iliac artery via the left common femoral contralateral access, the stent allegedly jumped back.It was further reported that the stent allegedly started to deploy on its own over the bifurcation before the operator unlocked the stent deployment system.Furthermore, it was also reported that the red unlock button was not released, but the stent deployment system was dislodged from the catheter and got stuck inside the patient.Reportedly, the broken catheter segment was tried to be snared out but was unsuccessful and a covered stent was used to push the broken segment against the vessel wall and was deployed inside the prematurely deployed stent.The current status of the patient is unknown.

Manufacturer Narrative

H10: additional information was received, and the file was reassessed for reportability and determined to be reportable as serious injury.H10: manufacturing review: the lot history records of this lot were reviewed with special attention to the manufacturing and inspection of this product and the product was found to have met the specification prior to shipment.Based on the information available it is not reasonably suggested that a manufacturing process may have caused or contributed to the reported issue.Investigation summary: the sample was returned for evaluation.The returned delivery system was found in used condition without stent, and with broken and detached inner catheter.The investigation leads to confirmed result for break, and detachment of the inner catheter.Provided images demonstrate that two stents with similar length have been placed overlapping so that only a small section of the stented segment was not overlapping at both ends, and that a piece of catheter was pinned to the vessel wall with a stent.Neither image nor sample can confirm premature deployment, system jumping upon insertion/ positioning, or malposition of the stent.The vessel was a little tortuous over the bifurcation, but not calcified.The user did not experience resistance during advancement, the guidewire was running smoothly inside the system, and the system was correctly held at the stability sheath during deployment.Based on the investigation of the provided information, the investigation is closed as confirmed for break and detachment of the inner catheter.A definite root cause for the reported event could not be determined.The reported indication represents an off label use.Labeling review: in reviewing the relevant labeling for this product, the potential issue was found addressed.The instruction for use state: 'if resistance is met during stent system introduction, the stent system should be withdrawn and another stent system should be used', and 'visually inspect the distal end of the stent system to ensure that the stent is contained within the sheath.Do not use if the stent is partially deployed'.Regarding access/ accessories the instruction for use state: 'gain ipsilateral or contralateral femoral access utilizing an appropriate introducer sheath ¿ 5f (1.67 mm) or larger introducer sheath.Insert a guidewire of appropriate length (table 2) and 0.014 inch (0.36 mm) - 0.035 inch (0.89 mm) diameter', and 'pre-dilatation of the lesion with a balloon dilatation catheter is recommended'.The instruction for use further state: 'prior to use flush the guidewire lumen of the stent system with heparinized normal saline until saline exits the tip of the system'.The lifestent 5f vascular stent system is intended to improve luminal diameter in the native superficial femoral artery (sfa) and popliteal artery.H10: d4 (expiration date: 03/2026).H11: section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.
