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 method for delivering a stent to a location within a vessel, said method comprising: introducing a delivery assembly into a catheter, the delivery assembly comprising (i) an elongate flexible member; and (ii) a retaining member, at a distal portion of the elongate member, having an inner lumen
1. A method for delivering a stent to a location within a vessel, said method comprising: introducing a delivery assembly into a catheter, the delivery assembly comprising (i) an elongate flexible member; and (ii) a retaining member, at a distal portion of the elongate member, having an inner lumen that extends around a circumference of the elongate member, the lumen receiving a first end of the stent to secure a portion of the stent in the retaining member;positioning the stent and a distal end of the catheter proximate an aneurysm within the vessel such that at least a portion of the stent is outside of the distal end of the catheter;rotating said retaining member relative to the stent, whereby the first end moves proximally relative to the retaining member and is disengaged from within the lumen while deploying said stent at the aneurysm. 2. The method according to claim 1, further comprising the step of removing the delivery assembly from within the catheter. 3. The method according to claim 1, further comprising the step of removing the catheter from within the vessel. 4. The method according to claim 1, further comprising the step of confirming the position of said stent prior to deploying said stent. 5. The method according to claim 1, wherein the stent is self-expanding. 6. The method according to claim 1, wherein the retaining member comprises a protective coil. 7. The method according to claim 1, further comprising limiting proximal movement of a second end of the stent along a length of the elongate member. 8. The method according to claim 1, wherein the first end of the stent is biased radially outwardly against the retaining member. 9. The method according to claim 1, wherein the delivery assembly further comprises a proximal member configured to limit proximal movement of a second end of the stent along a length of the flexible member, the method further comprising maintaining the retaining member and the proximal member substantially fixed axially with respect to each other while the stent is released from the lumen. 10. A method for positioning a self-expanding device at a treatment site in a vessel, the method comprising: introducing a catheter and a delivery assembly into the vessel, the delivery assembly comprising an elongate flexible member including a retaining member receiving a first end of the self-expanding device, the self-expanding device being concentrically within the retaining member and biased against a surface positioned about a lumen of the retaining member; andpositioning the catheter and the delivery assembly such that the retaining member and at least a portion of the self-expanding device are outside a distal end of the catheter and such that a second end of the self-expanding device is expanded toward a wall of the vessel;rotating the retaining member so as to release the first end of the self-expanding device from the retaining member by moving the first end proximally relative to the retaining member. 11. The method according to claim 10, wherein the treatment site comprises an aneurysm. 12. The method according to claim 10, wherein the retaining member comprises a protective coil, and the self-expanding device is received within an interior of the protective coil. 13. The method according to claim 10, further comprising removing the delivery assembly proximally through the catheter and leaving the self-expanding device in the vessel. 14. A method for delivering a self-expanding device in a body lumen, the method comprising: providing a delivery assembly positioned at least partially within an introducer sheath, the delivery assembly comprising an elongate flexible member and a retaining member at a distal portion of the delivery assembly, the elongate flexible member extending through the retaining member, the retaining member having a lumen therein extending around the elongate flexible member, the retaining member receiving a first end of the self-expanding device within the lumen, the self-expanding device being biased radially outward against the retaining member;advancing at least a portion of the delivery assembly through the introducer sheath and into a catheter;positioning the delivery assembly and the catheter at least partially within the body lumen such that the retaining member is outside a distal end of the catheter and at least a portion of the self-expanding device extends distal of the distal end of the catheter and such that a second end of the self-expanding device is expanded toward a wall of the body lumen;rotating the retaining member, whereby the first end moves proximally relative to the retaining member so as to release the first end from within the retaining member. 15. The method according to claim 14, wherein the assembly further comprises a second retaining member receiving a second end of the self-expanding device, the method further comprising releasing the second end of the self-expanding device from the second retaining member. 16. The method according to claim 14, wherein the retaining member comprises a protective coil, the self-expanding device received within an interior of the protective coil. 17. The method according to claim 14, further comprising inserting a distal end of the introducer sheath into a proximal end of the catheter, and removing the introducer sheath from the catheter after advancing the delivery assembly through the introducer sheath into the catheter. 18. The method according to claim 14, further comprising removing the delivery assembly proximally through the catheter and leaving the self-expanding device in the body lumen.
