It was reported that on (b)(6) 2013, the index procedure was to treat a heavily calcified lesion in the internal carotid artery.During deployment of the 9.0x40x136 xact, the stent jumped forward and was deployed partially in healthy tissue and partially in the target lesion.An unplanned 9.0x30x136 xact stent was deployed overlapping to treat the remainder of the target lesion.The procedure was completed without any adverse patient sequela or clinically significant delay in the procedure.On (b)(6) 2014, during regular angiographic check-up, it was noted that the overlapping portion of the two deployed stents had fractured struts.A non-abbott balloon dilatation catheter (bdc) was successfully advanced; however, the balloon ruptured during inflation.As the patient is non-symptomatic and the vessel is not blocked, the decision was made to abort further treatment and continue regular monitoring.The procedure was completed without any adverse patient sequela or clinically significant delay in the procedure.There was no additional information provided.
