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 review of the complaint history identified no other similar complaints from this lot.Based on the information received, the investigation determined that the reported balloon rupture and unexpected medial intervention appear to be related to operational context.There was no leak noted to the balloon during preparation, which suggests a product quality issue did not contribute to the reported difficulties.In this case, it is likely that the balloon interacted with the heavily calcified anatomy resulting in the reported balloon rupture during inflation.The reported patient effect of a perforation is listed in the percutaneous transluminal angioplasty (pta) catheter, armada 35 / armada 35 ll, global, instruction for use (ifu) as a known patient effect.A conclusive cause for the reported patient effect of a perforation and the relationship to the device, if any, cannot be determined.There is no indication of a product quality issue with respect to design, manufacture or labeling of the device.
