(b)(4).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 cable break appears to be related to user technique, as the user rotated the knob more than 270 degrees during device preparation, likely causing the cable to be over-tensioned, resulting in the break.The reported noise and subsequent inability to straighten the sgc are likely secondary effects/symptoms of the cable break.There is no indication of a product quality issue with respect to manufacture, design or labeling.
