1. A system for delivering a self-expanding device in a vessel, the system comprising:
- a delivery assembly comprising an elongate member and a retaining member, the retaining member positioned at a distal portion of the delivery assembly, the elongate member extending through a lumen of the retaining member, the lumen receiving an end of the self-expanding device such that the device end is radially disposed between the elongate member and the retaining member; and
a catheter configured to radially expand or radially collapse at least a portion of the self-expanding device by applying a pressure against an internal portion of the self-expanding device;
wherein the retaining member is rotatable relative to the self-expanding device, and wherein rotation of the retaining member moves the device end proximally relative to the retaining member, such that the device end is released from within the lumen.

Abstract
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.

10. A system for delivering a self-expanding device in a vessel, the system comprising:
-
a delivery assembly comprising an elongate member and a retaining member, the retaining member positioned at a distal portion of the delivery assembly, the elongate member extending through a lumen of the retaining member, the lumen receiving a distal portion of the self-expanding device, the device being concentrically constrained within the retaining member lumen and configured to radially expand against an internal surface of the retaining member; and a catheter configured to radially expand or radially collapse at least a portion of the self-expanding device by applying a pressure against an internal portion of the self-expanding device; wherein the retaining member is rotatable relative to the self-expanding device, and wherein rotation of the retaining member moves the device end proximally relative to the retaining member, such that the device end is released from within the lumen. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
