Abstract
An intravascular delivery system includes a threaded coil. The threaded coil includes one or more wires coiled to form a spiral coil with at least one thread extending along a length of the threaded coil. The threaded coil is plastically deformable for delivery of the threaded coil to a target location in the body and is rotatable to longitudinally position an intravascular device at the target location.

10. An intravascular device delivery system, the system comprising:
-
an elongated member having a proximal end, a distal end, and a longitudinal axis therebetween; a threaded coil positioned near the distal end of the elongated member, the threaded coil including; at least one elastically deformable wire spiraled about a longitudinal axis, the at least one elastically deformable wire defining a lumen therethrough and having at least one thread on a radially outer surface; and a drive cable positioned in the elongated member and extending from the proximal end to the threaded coil, the drive cable being rotationally fixed relative to the threaded coil. - View Dependent Claims (11, 12, 13)
