Additional procedural details were obtained from the reporting physician on a teleconference that was held on november 27th, 2023.It was pointed out by the physician that it seems that the device got caught on an undetectable piece of calcium which prevented proper deflation and retrieval.The device was discarded after use and therefore not available for return and investigation, however it was mentioned by the physician that the device was intact and fully deflated when removed from the patient.The physician also mentioned during the call that the patient was pretreated with aggrastat, which could have resulted in an excess bleeding.Based on the results of the investigation, dhr review, and procedure details, there is no indication that the device, labeling or packaging failed to meet its specifications when released.Potential adverse events such as dissection and hemorrhage are included in the device labelling.Consequently, it was determined that the reported adverse event is anticipated complication.
