The device was not returned for analysis.A review of the production records and the corrective and preventive actions (capa) database was performed and revealed no indication of a product quality issue.Additionally, a query of the complaint handling database for the reported lot revealed no indication of a lot specific issue.The investigation determined the reported difficulties appear to be related to the operational context of the procedure.It was reported that the balloon dilation catheter interacted with the patient¿s heavily calcified, mildly tortuous, and 90% stenosed lesion, resulting in difficulty during advancement.Additionally, it was reported that the balloon ruptured during inflation.It is possible that interaction between the balloon and the patient¿s heavily calcified lesion compromised the balloons integrity, contributing to the reported material rupture.There is no indication of a product quality issue with respect to manufacture, design, or labeling of the device.
