Abstract: A delivery system and method for a self-expandable implantable device are provided. The system includes an inner tube, an outer tube and an intermediate tube, wherein the outer tube is designed to be pulled proximally with respect to the intermediate and inner tubes, thereby releasing the implantable device. The system further includes a deployment sleeve with ridges for containment of the diverter, and an elliptical tip for insertion into a blood vessel. The system includes an ellipsoidal tip, which in one embodiment is mechanically connected to the inner tube. The implantable device comprises a diverter stent or graft.
