Event or Problem Description
On (b)(6) 2025, during an endovascular procedure involving the gore® tag® conformable thoracic stent graft with active control system, the device was advanced to the intended deployment site.The physician initiated the first stage of deployment by turning the primary deployment handle 90° counter-clockwise and pulling it to deploy the device to its intermediate diameter.However, the device remained fully constrained, and no deployment occurred.Although the primary deployment line detached along with the handle, the stent graft did not expand to its intermediate diameter.The physician subsequently withdrew the device from the patient.A second gore® tag® conformable thoracic stent graft with active control system was then used to complete the procedure successfully without further incident.It was noted that the backup hatch had been opened, but no primary deployment line was present.The patient tolerated the procedure well.The initial device was retained and will be returned to gore for evaluation.

Additional Manufacturer Narrative
The device evaluation showed the following: ¿ the fully deployed gore® tag® conformable thoracic stent graft with active control system (cmds) device was returned for evaluation.The line that remained connected to the primary deployment knob was identified to be returned at full length, with no indication of a tensile break.The observations of the device evaluation are consistent with the report of failure to initiate primary deployment.¿ there is potential for the report of failed primary deployment to be attributed to the primary and secondary deployment lines being switched and attached to the incorrect deployment knobs, but the root cause of the failed primary deployment could not be confirmed with the available information.¿ based on this investigation, there is potential for the failure mode to be attributable to the manufacturing process.The evaluated device was manufactured prior to the implementation of additional controls in which the sdl and sdl connector colors were changed to blue.The worst-case severity of harm that is reasonably foreseeable for this scenario is minor; therefore, no capa request is required.Events will continue to be monitored by gore.
