MAUDE Adverse Event Report: ENDOLOGIX (TRIVASCULAR) OVATION IX; AORTIC MAIN BODY

Model Number	TV-AB2380-J
Medical Device Problem Codes	Fluid/Blood Leak (1250); Material Integrity Problem (2978)
Health Effect - Clinical Codes	Low Blood Pressure/ Hypotension (1914); Failure of Implant (1924)
Date of Event	06/07/2019
Type of Reportable Event	Serious Injury
Additional Manufacturer Narrative
The lot history records related to the subject device referenced in this complaint record were reviewed for potential contributing factors for the failure mode(s) described in this event.A review of the device quality records showed that the device(s) demonstrated compliance to established procedures and specifications at the time of manufacture.
Event or Problem Description
An ovation ix abdominal stent graft system was implanted to treat an abdominal aortic aneurysm.Post polymer fill of the aortic body stent graft, the patient experienced hypotension and was successfully treated for an anaphylactic reaction per the device ifu.A decision was made to implant a palmaz stent at the level of the sealing rings.The aneurysm was excluded.The patient will continue to be monitored.
Additional Manufacturer Narrative
Clinical assessment was completed based on the received medical records.The reported polymer leak is unconfirmed.However, there was evidence to reasonably suggest a type ii endoleak (lumbar ¿ non-device related) and an intraoperative right renal snorkel placement (due to markers being placed at renal artery instead of below) had occurred that was not included in the event as reported.Device, user, procedure or anatomy relatedness of this event could not be determined.Procedure related harms for this complaint could not be determined.The final patient status was not reported.As identified in fs-0012, the root cause for most polymer leaks is a material weakness adjacent to the polymer fill channel which may become compromised during pressurization with liquid polymer.Since this device remains implanted, endologix is unable to conduct product evaluation to conclusively ascertain root cause.However, based on the investigation associated with this fsn, this is the most likely cause associated with this event.On 06aug2018, endologix issued a field safety notice (fs-0009) regarding the risk of polymer leak events with the ovation ix aortic body stent graft.On 06may2020, endologix issued a follow-up safety update (fs-0012) reaffirming treatment recommendations for patients who experience a polymer leak during implantation and providing updated information on the current rate of polymer leaks, the rate of clinical harms and root cause.The manufacturing lot evaluation confirmed all devices met specifications prior to release.The device was not returned as the device remains implanted therefore no evaluation was completed.No additional investigation of this reported event is planned however if additional information pertinent to the incident is obtained, a follow-up report will be submitted.Endologix will continue to monitor this complaint and similar complaints in the event further investigation is needed.
