(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.The steerable guide catheter was received.Investigation is not yet complete.A follow up report will be submitted with all additional relevant information.

This report is filed due to a suspected cable break.It was reported that during preparation of the steerable guide catheter, as the plus/minus (+/-) knob was turned by 3/4ths of a turn in the minus direction, resistance was noted and a noise was heard.The plus/minus cable was suspected to have broken.There was no patient involvement and the device was set aside for return.There was no additional information provided regarding the device issue.

(b)(4).Evaluation summary: all available information was investigated and the reported cable break resulting in mechanical issues was confirmed; however, the reported noise could not be tested.A review of the lot history record revealed no manufacturing nonconformities.Additionally, a review of the complaint history identified no other incidents reported from this lot.The investigation was unable to determine a conclusive cause for the steerable guide catheter (sgc) cable break resulting in the inability to straighten the guide and noise.It is possible that there were procedural interactions (e.G.Excessive knob turning and unintended curves on the device) which resulted in over-tensioning of the cables such that the cable broke; however, this cannot be definitively confirmed.There is no indication of a product quality issue with respect to manufacture, design, or labeling.
