(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.The device was not returned for analysis.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot.Additionally, a review of the complaint history identified no similar incidents reported from this lot.The investigation determined the reported steerable guide catheter (sgc) cable break appears to be related to patient morphology/pathology and due to the very tortuous anatomy; the reported noise (device operates differently than expected) was likely a secondary effect of the cable break.There is no indication of a product quality issue with respect to manufacture, design or labeling.
