It was reported that the device became entrapped on the guidewire, a loss of rotation occurred and the patient experienced an embolism.Vascular access was gained via the right common femoreal artery to treat the left leg using a non-bsc 7fr braided sheath.The aortic bifurcation had a sharp angle, requiring the braided sheath to provide support to gain access to the contralateral side.A jetstream xc atherectomy catheter and a jetstream console were selected for use in an atherectomy procedure in the heavily calcified distal popliteal artery, just past the knee joint.A non-bsc filter was in place and the jetstream catheter was advanced over a 315cm non-bsc guidewire.Two runs were performed with blades down then with blades up for another run.The catheter was moving up and down the wire initially without issue.The rex function was used every 30 seconds.At no point was the distal tip of the catheter sitting on the wire during operation or while the tip was rotating for longer than a few seconds, as confirmed by the wire loop in the wire guard increasing and decreasing during the operation.As the case progressed, the catheter became more and more difficult to move along the wire.A second proximal lesion in the superficial femoral artery (sfa) was treated with 1 to 2 passed on blades down; however the catheter became impossible to move along the wire.In addition, despite pressing the forward button on the jetstream, the motor on the jetstream console would no longer rotate.There was a small wirrr sound for about a second, but then the jetstream was silent.This occurred at about 10 minutes of jetstream usage time, as indicated on the jetstream console.As a result, the entire system had to be pulled out of the leg and through the sheath as one unit.The patient subsequently had tibial emboli that was treated successfully but resulted in longer procedure time.
