The unique device identifier (udi) is unknown because the part and lot numbers were not provided.The product was not returned to abbott vascular for analysis.A review of the electronic lot history record (elhr), corrective action tracking system for the web (catsweb) database review and similar incident query was not performed since the lot number was not reported and the device was not returned for analysis.In this case, the device was prepped prior to use and inflated once prior to the balloon rupture without any leaks or ruptures noted.The investigation determined the reported balloon rupture and entrapment of the device appear to be related to operational circumstances of the procedure.Based on the reported information, during the second inflation, the balloon ruptured at 16 atmospheres.It is likely that during the second inflation the balloon became damaged against the previously implanted stent resulting in the reported balloon rupture.The ruptured balloon did not properly refold and became tangled with the stent.Additionally, the treatment appears to be related to the operational context of the procedure as the patient was taken to surgery to remove the device.There is no indication of a product quality issue with respect to manufacture, design or labeling.
