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.A conclusive cause for the reported patient-device incompatibility (failure to seal) could not be determined; however, the subsequent medication required appears to be related to the operational context of the procedure.Patient-device incompatibility (failure to seal the perforation) may be attributed to several factors including, but not limited to, patient anatomical morphology, product size selection, deployment technique, interference from previously deployed devices, or growth of perforation during deployment.In this case, it is possible that growth of the perforation during deployment may have contributed to the reported patient-device incompatibility (failure to seal); however, based on the information provided, this cannot be confirmed.There is no indication of a product quality issue with respect to manufacture, design, or labeling.
