Device evaluated by mfr: the device was returned for analysis.Returned product consisted of the rotablator rotalink burr catheter, however, the rotablator rotalink advancer device was not returned for analysis.The handshake connections, sheath, and coil were microscopically and visually inspected.There were numerous kinks throughout the sheath.The sheath was split/torn 17cm distal of the strain relief.There was blood in the sheath due split/torn sheath.The split/torn shaft is consistent to damage caused by the hemostasis valve being over tightened.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.The investigation conclusion is handling damage as the complaint was caused by handling of the device or portion of the device without direct patient contact.(b)(4).
