Device evaluated by manufacturer: returned product consisted of a guidezilla guide extension catheter with a non-bsc stented balloon catheter (4.0mm x 34mm).There were numerous kinks throughout the hypotube of the non-bsc device, with stent damage and tip damage.There was blood inside and outside of the guidezilla distal shaft.The hypotube, collar, distal shaft and tip were microscopically and tactile inspected.Inspection revealed a partial separation at the collar and a kink in the distal shaft, located 35mm from the tip.The inner diameter (id) of the guidezilla was measured at the distal tip and was within specification.A.057¿ tooling qualified mandrel was inserted through the collar with no resistance.Functional testing was attempted by inserting the non-bsc device into the collar of the guidezilla device; however, due to the damaged stent, the device was not able to be inserted.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).
