Physician was attempting to use an everflex entrust pta balloon along with non medtronic 6fr sheath and 0.035 guide wire during procedure to treat a severely calcified lesion in the right distal sfa with 70% stenosis.Vessel is none tortuous.The vessel diameter and lesion length are 5mm and 3-4cm respectively.The device was prepped per ifu with no issues identified.It was reported that the stent was deployed in an unintended lesion site.The stent partially deployed (1cm of the tip of the stent was released) before reaching the target lesion and without pulling the lock pin, physician did not intend to release the stent there.The lesion was not pre dilated.The device did not pass through a previously deployed stent.Resistance was encountered when advancing the device with no excessive force used.After the partial deployment of the stent proximal to the target lesion, physician deployed the stent completely at that point (distal part of sfa).Physician decided to use a non medtronic stent (6x80), to cover both the everflex stent and the target lesion.It was not easy to push the catheter forward due to the cross over intervention.The iliac and all parts of sfa were severely calcified.There was no patient injury reported.
