Patent ID: 8273101

Claim:
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.
