The device was not returned for analysis.A review of the lot history record revealed no manufacturing nonconformities that would have contributed to this complaint.Additionally, a review of the complaint history identified no other incidents.The investigation determined the reported difficulties appear to be related to circumstances of the procedure, as it is likely the balloon-expandable stent (bes) interacted with the 6f (french) sheath during retraction of the device causing the reported difficult to remove.Further interaction with the sheath caused the device to become stuck, ultimately stretching the stent, contributing the reported material deformation (flared stent struts).There is no indication of a product quality issue with respect to manufacture, design, or labeling.

It was reported that the procedure was to treat a mildly calcified, 50% stenosed lesion in the left external iliac artery.An 8x59mm omni elite balloon-expandable stent (bes) was advanced through a 6f (french) sheath, and advanced to the target lesion.Once at the lesion to be treated, it was noticed that the stent was too long for the lesion.An attempt was made to withdrawal the bes from the sheath; however, it became stuck and stretched with flared struts.The bes and the sheath had to be removed as a single unit.Guide wire (gw) access was maintained.There was no adverse patient effect and no clinically significant delay in the procedure.A new sheath and 7x39mm omnilink bes were used to successfully complete the procedure.No additional information was provided.
