Use of first (previous) device during this procedure is described and investigated in 3008439199-2020-00021.Dr.(b)(6) decided a second device was appropriate at this time.The 2nd device was run up and over without incident and down to the lesion.Again, after a minute or so, the clutch began to slip o rotarex.Dr.(b)(6) decided it would be appropriate to put a 4mm balloon down so he began removing the device.As he was removing, he noticed that the tip of rotarex was not moving with the catheter.He examined the catheter under flouro and we couldn't see if it was broken so he continued with trying to remove the device slowly.As he removed rotarex, he was not feeling any resistance and it was determined the helix was no longer attached.He was able to snare the helix in an attempt to pull it out through the sheath.Dr.(b)(6) was able to get the tip pulled back up to the right cfa before the patient complained of discomfort in his right groin area.At that time dr.(b)(6) decided to do a cut down of the right cfa to remove the helix.When dr.(b)(6) got to the helix he said it still felt stuck and was not coming out easily.At that time it was determined there was a perforation at the bifurcation and he opened the patient up.Dr.(b)(6) was able to retrieve the device after cutting it in half.Patient is in stable condition as of this morning.
