The device was not returned for analysis.Production record and corrective and preventative actions (capa) reviews were performed and revealed no indication of a product quality issue.Additionally, a query of the complaint handling database for the reported lot revealed there is no indication of a lot specific issue.Based on the information provided, a definitive cause for the reported difficulties could not be determined.In this case, it is possible that interaction between the device and the patient's heavily calcified, moderately tortuous anatomy and 90% stenosed lesion contributed to the difficulty in advancing the device, resulting in the reported balloon material rupture and subsequent stent activation failure.However, because the device was not returned for analysis, this cannot be confirmed.There was no damage noted to the device during the inspection prior to use which suggests a product quality issue with respect to manufacture, design or labeling did not contribute to the reported difficulties.
