The GORE® ACTIVE CONTROL System provides controlled, two-stage deployment, with primary deployment to an intermediate diameter and a secondary deployment to full diameter. This design allows for continuous blood flow throughout the deployment with multiple opportunities to visualize and refine graft placement. It is also designed to allow for angulation of the proximal end of the device for improved seal and apposition. It gives physicians added precision in placement and angulation so they can take full advantage of the exceptional conformability of the Gore device and confidently provide a minimally-invasive solution to more patients.
