It was reported that the jetstream catheter and the wire became stuck resulting in an embolism.A 2.1mm jetstream xc atherectomy catheter and abbott barewire 315cm were selected for treatment of instent restenosis/thrombosis, total treatment was approximately 200mm (3 month old, blocked stent).The customer was instructed to go slowly advancing the jetstream catheter, treating 3cm sections at a time then using rex mode to go distal to proximal.After only one run (approximately 3.17 minutes) through with the blades down through long stent with mixed morphology, the physician was unable to remove the jetstream catheter as it was stuck with the wire.The entire system with filter and wire needed to be removed together resulting in some distal thrombo-embolization and the early cessation of the atherectomy part of the procedure.The physician used the jetstream aspiration as intervention for the embolization; however, they were not able remove all of the embolism.It was noted that there appeared to be more saline going in than what was in the waste back (volume-wise), although they did not observe a loss of aspiration and bubbles were flowing back at all times.When the device and wire were removed, the physician pulled on the wire end to try and see if it could be detached and at that point the wire unraveled.There was a big kink made in the catheter during removal of the device, but there didn't appear to be any prior to the device getting stuck on the wire.The procedure was completed using an alternate method, and the patient was expected to make a full recovery.

Device eval by manufacturer: this 2.1mm jetstream xc atherectomy catheter was returned and analyzed.Visual examination revealed severe damage on the catheter shaft.Only a small piece of the abbott barewire was returned stuck in the device tip.The wire was sticking out of the tip approximately 5 cm and had been separated.The outer sheath had been stretched and pulled away from the device approximately 1.5 cm from the tip.There was a severe kink located 22 cm from the tip.The device was set up per the instructions for use (ifu) and the device primed; however, no rotation was seen due to the severe damage on the device.Inspection of the remainder of the device, apart from the observed damage revealed no other damage or irregularities.This event was confirmed for guidewire entrapment (and subsequent damage) related to the use of a non-compatible guidewire with the jetstream system.
