The catalog number identified has not been cleared in the us but is similar to the lifestream products that are cleared in the us.The pro code and 510 k number for the lifestream products are identified in common device name and pma/510k.Manufacturing review: a complaint history review was performed.This is the fourth complaint reported for this lot number.The device history records were reviewed and there was nothing found to indicate there was a manufacturing related cause for this event.Investigation summary: the device was returned.There was no stent present on the balloon.The balloon showed evidence of inflation.A longitudinal burst was confirmed along the length of the balloon from the distal cone to the proximal cone.The balloon exhibited stent crimp impressions which indicated that a stent had been present on the balloon during manufacture.Review of fluoroscopy and external imagery was unable to confirm the presence of a stent.The result of the investigation is confirmed for the reported stent missing issue.The root cause for the reported stent missing issue could not be determined based upon the available information received from the field communications, device evaluation and images review.Labeling review: the instructions for use for the lifestream product was reviewed and contains the following information relevant to the reported event: warnings: 1.Do not use if packaging/pouch is damaged.Precautions: 2.The device should only be used by physicians who are trained in endovascular procedures and are familiar with the complications, side effects and hazards of peripheral vascular interventions.3.Prior to device use, refer to the covered stent sizing table on the label and read the instructions for use.Directions for use: endovascular system preparation: 4.Carefully remove the selected device from the package.5.Inspect the covered stent for adherence to the balloon and centered placement in relation to the balloon marker bands.If the covered stent is not centered and/or does not firmly adhere to the balloon, do not use.Introduction of the endovascular system and placement of the covered stent: 13.Advance the endovascular system over the guidewire into the introducer sheath.14.Further advance the endovascular system to the target treatment site within the introducer sheath and position the covered stent across the lesion.Verify that the covered stent is still centered within the balloon marker bands.Slowly retract the introducer sheath / guiding catheter while maintaining the position of the covered stent.Ensure the introducer sheath is retracted far enough to not compromise the balloon expansion and covered stent release.15.Slowly inflate the endovascular system balloon to nominal pressure, expanding the covered stent.Confirm complete expansion via fluoroscopic visualization.A 15 ¿ 30 second inflation time is recommended.Important: do not exceed the rated burst pressure of the delivery system.16.After covered stent deployment, apply negative pressure to the balloon until it is fully deflated.Withdraw the delivery system while maintaining negative pressure with the guidewire remaining across the lesion.17.Confirm optimal covered stent wall apposition using standard angiographic techniques.If the covered stent has not achieved full wall apposition, a post dilation with an appropriately sized balloon should be performed.5-8 mm devices may be post-dilated with balloons up to 10 mm in diameter.9-12 mm devices may be post-dilated with balloons up to 12 mm in diameter.(expiration date: 05/2023).
