Physician was attempting to use a silverhawk directional atherectomy along with non-medtronic 6fr sheath and non-medtronic.014 guide wire to treat a vessel.The vessel was not pre dilated.Ifu was followed during preparation, procedure and post procedure.The guide wire was hydrated at preparation.The guide wire did not have difficulty accessing ports and the device was not advanced over a bifurcation.It was reported that during advancement, minimal resistance was felt.The guide wire lumen was torn from the distal tip which caused guide wire lock-up on catheter.Upon loading the atherectomy catheter on the guide wire, the device hung up on the wire not allowing device to advance across the guide wire.The guide wire was pulled from lumen with resistance.There was no damage to the guidewire tip.Another silverhawk ss+ was used to complete the procedure.There was no patient injury reported.
