It was reported the procedure was to treat a de novo lesion with mild tortuosity, mild calcification and 90% stenosis in the internal carotid artery.The acculink was unpacked and prepped as recommended in the instructions for use and no damage to the device was noted.The acculink was advanced without issue to the target lesion.During deployment, the lock was totally unlocked; however, after the first centimeter of deployment of the stent, the distal part of the handle broke into pieces with normal hand force.There was no further movement possible to release the acculink; therefore, the handle had to be broken into more pieces to deliver and deploy the acculink stent at the lesion.There was no further complication in the procedure.There was no adverse patient effect and no clinically significant delay in the procedure.No additional information was provided.
