AVP device for TIPS occlusion in a patient with life-incapacitating hepatic encephalopathy. The 14-mm-diameter AVP is positioned through a guiding catheter in the central portion of the 10-mm-diameter e-PTFE stent-graft (a). By retraction of the guide wire, the unconstrained AVP sets in the intended place (b). At this point, the AVP can still be retracted into the guiding catheter if in an unsatisfactory position. The AVP is fully deployed by unscrewing the guide wire from the AVP device proper (c)
