During incoming inspection, the distributor rejected this device, 138105, for an insufficient heatseal.There was no contact with the patient as this was found during incoming inspection.Due to the potential severity of a breach in sterility, this complaint meets the criteria for a reportable event.This will be reported as a malfunction with potential for injury upon reoccurrence.
