Same case as:2134265-2014-07849.It was reported that the burr was stuck on rotawire.A 99% stenosed target lesion was located in the moderately tortuous and severely calcified mid left anterior descending artery.A 1.25mm rotalink¿ plus and a 330cm rotawire¿ and wireclip¿ torquer were used for treatment.During platforming, rotational speed was checked using dynaglide mode and was noticed to be working properly as it went up to 200,000 rpm outside the body.However, abnormal sound was heard and the device stalled.The rotablator system was then removed from the body.It was then noted that the rotawire got stuck with the burr.Separating the rotawire from the burr was unsuccessful.The procedure was completed with a 1.5mm rota burr and 330cm rotawire.There were no complications reported and the patient's status was good.

Device evaluated by mfr: the complaint unit was returned connected to the catheter.A visual examination of the complaint unit was carried out and no issues were noted.The advancer knob was locked upon return in a backward position; it was loosened and advanced in order to inspect the handshake connection.The handshake connection was inspected and no damage was noted.A handshake connection test was attempted to examine the integrity of the connection.No issues were noted.The drive shaft, coil and sheath were inspected and there was no damage noted.A guidewire was returned running through the device.The guidewire was removed with no resistance encountered.A wet test was performed and the device was unable to reach optimum speed of 176k rpm at 40 psi.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The root cause is not confirmed as there was no evidence of the alleged issue or any anomalies which could have contributed to the reported difficulty.(b)(4).

It was further reported that after the devices were removed from the patient, the rotawire was observed to be separated.Another unspecified size rotawire was attempted to be inserted into the same burr; however, the burr was blocked.It was believed that the wire separated as the wire came in contact with the burr.
