Device lot number corrected from 19150629 to 0017471298.Batch expiration date corrected from 31-mar-2018 to 31-oct-2016.Batch manufactured date corrected from 25-apr-2016 to 25-nov-2014.Device evaluated by mfr: the device was returned for analysis.Microscopic and visual inspection were performed on the sheath, coil , burr, annulus and handshake connections.The sheath was separated 29cm ¿ 35cm from the distal of the sheath.The separated ends appeared to be jagged and damaged, which indicates that the separation was due to tensile overload.Functional test was performed by connecting the rotablator rotalink plus device to a rotablator control console system.There was water leaking from the separation in the sheath and the device was not able to get any speed.The advancer was dismantled and the turbine was found to be corroded and the ultem was found to be melted.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The most probable root cause is operational context as device performance was limited due to anatomical/procedural factors.(b)(4).
