Event Description

The following was reported to gore: on (b)(6) 2022, a thrombectomy was performed prior to device placement.Treatment was performed due to an aneurysm in the subclavian artery.A 7fr x 45cm terumo sheath was used to advance a 7x29 gore® viabahn® vbx balloon expandable endoprosthesis (vbx device).The vbx device was implanted with good results.The patient did not experience any adverse consequences during this treatment.Later the same day, the patient was brought back into the operating room because the 7x29 vbx device had occluded.Intervention was performed with an 8x29 vbx device that extended from the first device and into the aorta.Completion angiography showed the vbx device was open with good flow at conclusion of procedure.Post-operatively on (b)(6) 2022, the patient experienced a right side, posterior circulation stroke.The patient has multiple areas of stroke, echo negative.The physician reported the patient cannot move his left arm and exhibited confusion.The patient's mental status has somewhat improved, although still experiencing some slurred speech/dysarthria as of on (b)(6) 2022.The physician stated that not initially extending the vbx device into the aorta may have possibly caused the occlusion.Other possible explanation was a small calcification or dissection that was not appreciated on angiography.Imaging showed the vbx device remains fully expanded and no collapse was noted.There were no structural deformities seen in the vbx device.

Manufacturer Narrative

Cbas® heparin surface incorporates cbas-heparin manufactured from heparin sodium api, which is covalently bound to the device surface and is essentially non-eluting.Patient weight, age/dob, relevant medical history and medications were requested, but not made available.Results pending completion of engineering evaluation.Ifu for gore® viabahn® vbx balloon expandable endoprosthesis hazards and adverse events state: procedure related: as with all procedures that utilize techniques for introducing a catheter into a vessel, complications may be expected.These complications include, but are not limited to: access site infection; entry site bleeding and/or hematoma; vessel thrombosis, occlusion, pseudoaneurysm, and trauma to the vessel wall (including rupture or dissection); distal embolization; arteriovenous fistula formation; transient or permanent contrast induced renal failure; renal toxicity; sepsis; shock; radiation injury; myocardial infarction; fever; pain; malposition; malapposition; inflammation; and/or death.A possible complication which may occur in conjunction with the use of systemic heparin: hit type ii.Device related: complications and adverse events can occur when using any endovascular device.These complications include, but are not limited to: hematoma; stenosis, thrombosis or occlusion; distal embolism; side branch occlusion; vessel wall trauma and/or rupture; false aneurysm; infection; inflammation; fever and/or pain in the absence of infection; deployment failure; migration; and device failure.

Manufacturer Narrative

Device remains implanted; therefore, direct product analysis was not possible.The reported complaint information does not reasonably suggest a potential malfunction has occurred.Additional information obtained from physician indicates the reported failure mode, related to device occlusion, may have been caused by not initially extending the vbx device into the aorta.Other possible explanation was a small calcification or dissection that was not appreciated on angiography.The vbx stent was fully expanded and did not collapse.There were no structural deformities noted in the vbx device.D9: device remains implanted; was not returned.Direct product analysis could not be conducted.

Manufacturer Narrative

Gore® viabahn® vbx balloon expandable endoprosthesis (vbx device), catalog number bxa072902a, device lot/serial number (b)(6); udi number (b)(4).This 7 x 29 vbx device was initially implanted in the patient.A second vbx device (8mm x 29mm) was used to extend the initially implanted device.The vbx devices are same device type and the both were implanted in the same target treatment area.For lot/serial number 24817419, a review of manufacturing records verified that the lot involved in this complaint met all pre-release specifications.The implanting physician stated that not initially extending the vbx device into the aorta may have possibly caused the occlusion.Other possible explanation was a small calcification or dissection that was not appreciated on angiography.The vbx device was fully expanded and was not collapsed.There were no structural deformities noted.
