It was reported that the procedure was to treat a lesion in the left common iliac artery with heavy calcification.Pre-dilatation was performed using an armada 35 balloon without issues.The 9.0x39mm omnilink elite stent delivery system (sds) was deployed, however, the balloon got stuck in the 6french (f) sheath even after the balloon was deflated several times.The entire sheath with the wire and sds had to be removed.Due to longer manual compression and a compression bandage had to be applied, the patient had to lie down for 8 hours instead of 4-6 hours.Although there was a delay in the procedure, there was no adverse patient effect; hence no patient harm.No additional information was provided.

A visual and functional inspection was performed on the returned device.The reported difficult to remove was confirmed.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no similar incidents from this lot.The investigation was unable to determine a conclusive cause for the reported difficult to remove; however, factors that can contribute to difficult to remove include, but are not limited to, guiding catheter lumen obstructions, kinks, bends, procedural technique, insufficient support, or interactions with accessory devices.Based on the information provided and the condition of the returned device, a conclusive cause for the reported difficult to remove could not be determined; however, the observed deformation due to compressive stress (kinked shaft) and stretched shaft likely occurred while attempting to remove the device from the introducer sheath.There is no indication of a product quality issue with respect to manufacture, design, or labeling.
