Event Description
|
It was reported that during a stent placement procedure for lower extremity arteriovenous stenosis via lower extremity arteries, when the stent was inserted over the guide wire and released, it was measured to be over one hundred and twenty millimeter in length, extending beyond the planned position.It was further reported that as the stent length was longer than the nominal length, healthy tissue was also covered by the stent in addition to the part where it was planned to be placed.There was no reported patient injury.

H10: the catalog number identified in section d4 has not been cleared in the us but is similar to the lifestar vascular stent that are cleared in the us.The pro code and 510 k number for the lifestar vascular stent are identified in d2 and g4.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 physical sample was not available for evaluation.Provided image demonstrates the deployed stent inside patient including a digital length measurement of 135mm from marker to marker which indicates stent elongation of the 120mm stent.A detailed strut analysis for elongation was not possible due to poor resolution.The vessel was not tortuous/ calcified, and the user pined the grip in place, and removed slack before deployment; the target site was seen between the markers before deployment, and the system was kept straight; the user did not experience difficulty during deployment.Based on the investigation of the provided information, the investigation is closed as confirmed for stent elongation.A definite root cause for the reported event could not be determined.Labeling review: in reviewing the relevant labeling for this product the potential issue was found addressed.The instructions for use closely describe holding and handling of the system during deployment; in particular the instructions for use state: 'prior to stent deployment, remove all slack from the catheter delivery system to avoid stent misplacement.', and 'deploy the stent using the ¿pin & pull-back¿ technique by slowly pulling back the distal t-luer adapter (f) towards the hand that is pinned in place', and 'the radiopaque markers on the stent must not move during stent deployment.' in regard to access and accessories the instructions for use state: 'the lifestar vascular stent system is only compatible with a 0.035-inch (0.89 mm) guidewire.', and 'the 6f delivery system requires a minimum 8f guiding catheter, or a minimum 6f introducer sheath.', and 'via the femoral route, insert a 0.035-inch (0.89 mm) guidewire under fluoroscopic guidance through the appropriate introducer sheath or guiding catheter and pass the lesion.' in regard to pta the instructions for use state: 'pre-dilatation of the stricture is recommended.' in regard to stent size selection the instructions for use state: 'allow approximately 5 ¿ 10 mm of the stent to extend beyond each end of the stricture.', and 'the lifestar vascular stent experiences length changes less than 10% during deployment if appropriate oversizing is used.H10: d4 (expiration date: 09/2025).H11: section a through f ¿ the information provided by bd represents all 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.H3 other text : device not returned.
