System and method for delivering and deploying an occluding device within a vessel
First Claim
1. A system for deploying an occluding device, the system comprising:
- an elongate member;
a self-expanding device within a lumen of the elongate member;
an assembly including an innermost delivery wire extending through a lumen of the device, the delivery wire having a device retaining member for receiving a first end of the device and a proximally positioned retaining member for engaging a second end of the device when the device is positioned against said proximally positioned retaining member;
wherein at least a portion of the delivery wire is radially constrained by the elongate member and the device as the device and the at least a portion of the delivery wire remain within the elongate member;
wherein the delivery wire is configured to move in a non-rectilinear manner as the device retaining member and the proximally positioned retaining member move longitudinally relative to each other and as the device expands radially and is deployed into, and engages a wall of, a vessel;
wherein the device is configured to foreshorten longitudinally as the device self-expands into a vessel lumen; and
wherein the assembly is configured to foreshorten longitudinally, while releasing the device, at a slower rate than the device foreshortens.

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. The elongated flexible member may be a integral portion formed thereof that form a coil portion.

9. A system for supporting and deploying an occluding device, the system comprising:
-
an elongate member; a self-expanding device within a lumen of the elongate member; an assembly for carrying the device;
the assembly including an innermost delivery wire extending through a lumen of the device, the delivery wire having a device retaining member for receiving a first end of the device, a proximally positioned retaining member for engaging a second end of the device when the device is positioned against said proximally positioned retaining member;wherein at least a portion of the delivery wire is radially constrained by the elongate member and the device as the device and the at least a portion of the delivery wire remain within the elongate member; wherein at least a portion of the delivery wire is configured to form a pattern of peaks when the first end of the device and the second end of the device translate in relation to each other along a length of the assembly as the device is deployed; wherein the first end of the device and the second end of the device are configured to translate relative to each other along a length of the assembly at a first rate; and wherein the device retaining member and the proximally positioned retaining member are configured to translate relative to each other along the length of the assembly at a second rate, slower than the first rate. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
