Device evaluated by manufacturer: returned product consisted of the rotalink burr catheter for the complaint device; however, the advancer for the complaint was not returned.Following analysis, the handshake connection, sheath, coil, and burr were microscopically and visually inspected.There was blood in the sheath.The annulus of the burr was flared, damaged, and not rounded.The damage to the annulus is consistent with damage caused by the rotating burr coming into contact with the guidewire during use, leading to the damaged annulus.An attempt to remove the rotawire was unsuccessful.The burr and wire were soaked for 5 minutes in hot water and the devices were still unable to be separated.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.The investigation conclusion is operational context as the product meets the design & manufacture specification but due to anatomical/procedural factors encountered during the procedure, performance was limited.(b)(4).
