Abstract
A device for delivering and deploying a graft stent complex comprises a flexible guide sheath, the outer diameter of the guide sheath being constant throughout its length and the inner diameter of the guide sheath increasing from the proximal end to the distal end. A hemostatic valve having at least two ports is attached to the proximal end of the guide sheath, one port adapted to permit passage of a catheter into the guide sheath and the other port adapted to permit passage of a fluid into the guide sheath. A lead balloon catheter extends through the first port into the guide sheath, and includes an inflatable lead balloon at its distal end. A portion of the lead balloon extends from the distal end of the guide sheath to provide a tapered leading surface and also to seal the distal end of the guide sheath. Deployment means are provided within the guide sheath, with the stent being mounted on the deployment means. The deployment means includes an elongated shaft having a guide wire lumen disposed in colinear relationship with the guide wire lumen of the lead balloon catheter. Fluid may be applied under pressure to the second port of the hemostatic valve to vary the flexibility of the guide sheath.
