A system and method for deploying an occluding device that can be used to remodel an aneurysm within the vessel by, for example, neck reconstruction or balloon remodeling. The system comprises an introducer sheath and an assembly for carrying the occluding device. The assembly includes an elongated flexible member having an occluding device retaining member for receiving a first end of the occluding device, a proximally positioned retaining member for engaging a second end of the occluding device and a support surrounding a portion of the elongated flexible member over which the occluding device can be positioned.
1. A system for delivering a self-expanding device, said system comprising: a self-expanding device;an introducer sheath; andan assembly comprising: an elongate flexible member;a retaining member configured to receive an entire circumference of a first end of the self-expanding device into a proxima
1. A system for delivering a self-expanding device, said system comprising: a self-expanding device;an introducer sheath; andan assembly comprising: an elongate flexible member;a retaining member configured to receive an entire circumference of a first end of the self-expanding device into a proximalmost opening of, and concentrically within, an interior portion of the retaining member, the retaining member being sized for placement within the sheath;a proximally positioned member positioned proximally of a second end of the self-expanding device and configured to inhibit proximal movement of the self-expanding device along the flexible member when the self-expanding device is carried by said assembly and positioned against said proximally positioned member, the proximally positioned member comprising a first coil; anda second coil surrounding a portion of said elongate flexible member between the proximally positioned member and the retaining member such that the second coil underlies the self-expanding device when the assembly carries the self-expanding device. 2. The system of claim 1, wherein the proximally positioned member urges the self-expanding device toward a distal end of the flexible member when the self-expanding device is carried by said assembly and positioned against said proximally positioned member. 3. The system of claim 1, wherein the proximally positioned member further comprises a cap positioned distally of the first coil such that the cap is positioned between the first coil and the self-expanding device when the self expanding device is carried by the assembly. 4. The system of claim 3, wherein the first coil biases the cap distally against the self-expanding device when the self-expanding device and the cap are engaged. 5. The system of claim 1, wherein the second coil comprises an outwardly facing surface contacting an inner surface of the self-expanding device. 6. The system of claim 1, wherein the second coil is configured to maintain the self-expanding device in a ready-to-deploy state. 7. The system of claim 1, wherein the elongate flexible member is tapered in a region underlying the second coil. 8. The system of claim 1, wherein the second coil is sized such that the second coil engages the self-expanding device when the self-expanding device (i) is carried by the assembly, (ii) is positioned within the introducer sheath, and (iii) engages an internal surface of the introducer sheath. 9. The system of claim 1, wherein the second coil is secured to the elongate flexible member by at least one of soldering, welding, RF welding, glue, or other adhesive. 10. The system of claim 1, wherein the retaining member comprises a third coil. 11. The system of claim 1, wherein rotation of the retaining member results in disengagement of the first end from within the interior portion. 12. The system of claim 1, wherein said elongate flexible member comprises a flexible atraumatic tip positioned distally of the retaining member. 13. The system of claim 1, wherein said elongate flexible member comprises at least two sections having different diameters. 14. The system of claim 1, wherein said elongate flexible member comprises sections of differing flexions. 15. The system of claim 1, further comprising a catheter into which said assembly and the self-expanding device can be positioned. 16. The system of claim 1, wherein said retaining member and first coil remain substantially axially fixed with respect to each other during release of the self-expanding device from the retaining member. 17. A system for delivering a self-expanding device, said system comprising: a sheath;a self-expanding device positioned within the sheath;an elongate flexible member extending through the self-expanding device within the sheath;a retaining member comprising an interior portion surrounding the elongate flexible member, an entire circumference of a first end of the self-expanding device being positioned concentrically within the interior portion and extending proximally through a proximalmost opening of the interior portion;a proximally positioned member, comprising a first coil, positioned proximally of and contacting a second end of the self-expanding device, the proximally positioned member inhibiting proximal movement of the self-expanding device along the flexible member; anda second coil that (i) surrounds a portion of said elongate flexible member between the proximally positioned member and the retaining member and (ii) is positioned between the self-expanding device and the elongate flexible member. 18. The system of claim 17, wherein the proximally positioned member urges the self-expanding device toward a distal end of the flexible member. 19. The system of claim 17, wherein the proximally positioned member further comprises a cap positioned distally of the first coil and proximally of the second end of the self-expanding device. 20. The system of claim 17, wherein the second coil comprises an outwardly facing surface contacting an inner surface of the self-expanding device.
