(b)(4).The device was not returned for evaluation.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other incidents and/or complaints from this lot.Based on the information provided, the reported difficulties appear to be related to case circumstances.It is likely that the balloon rupture was the result of interaction with the heavily calcified lesion resulting in partial deployment of the stent.The additional therapy/non-surgical treatment was also due to circumstances of the procedure as an unspecified balloon catheter was used to post-dilate the stent to achieve wall apposition.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
