It was reported that the procedure was to treat a mildly calcified vessel in the iliac artery.The 7.0x120mm absolute pro self expanding stent system (sess) was advanced without resistance and the stent was successfully deployed.However, during catheter removal, the handle detached from the catheter.There was no resistance during withdrawal and force was not applied, the separated shaft was simply pulled out to retrieve it.An angiographic check was performed to verify the position of the stent in the vessel.There were no adverse patient effects and there was no clinically significant delay in the procedure.No additional information was provided.

The device was returned for analysis.The reported material separation was able to be 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 other incidents from this lot.As there was no damage noted to the device during the inspection prior to use, it is possible that during use and/or during removal inadvertent mishandling resulted in the noted smashed outer member, the noted i-beam bend/separation and ultimately resulted in the reported/noted material separation (hypotube separated from the guide wire port/luer); however this cannot be confirmed.The investigation determined a conclusive cause for the reported/noted material separation cannot be determined.The noted multiple kinks (jacket, inner member, distal sheath, stabilizer) likely occurred due to handling or during packing for return analysis.There is no indication of a product quality issue with respect to manufacture, design or labeling.
