INTRAVASCULAR FLOW MODIFIER AND REINFORCEMENT DEVICE AND DEPLOYMENT SYSTEM FOR SAME
First Claim
1. A system for deploying an intravascular flow modifier and reinforcement device for use in the intravascular treatment of a target site in a patient'"'"'s vasculature, the system comprising:
- an intravascular flow modifier and reinforcement device including a generally cylindrical frame formed of an elongate resilient wire configured as a series of a plurality of helical windings;
a substantially tubular pusher catheter member having an inner lumen, a proximal portion, a distal portion, a tubular main shaft, and a notched portion including a first plurality of alternating notches and tubular shoulder portions formed in one side of the shaft of the pusher catheter member, and a second plurality of notches on an opposing side of the shaft of the pusher catheter member, each of said notches receiving a plurality of the plurality of helical windings; and
a delivery catheter configured to removably retain said at least one helical winding on said notched portion of said pusher catheter member, wherein said substantially tubular pusher catheter member and the intravascular flow modifier and reinforcement device received on said notched portion of said pusher catheter member are disposed in the delivery catheter, and wherein said delivery catheter is configured to be withdrawn from said notched portion of said pusher catheter member when the intravascular flow modifier and reinforcement device is positioned at the site in the patient'"'"'s vasculature to be treated for delivery of the intravascular flow modifier and reinforcement device to the site in the patient'"'"'s vasculature to be treated.

Abstract
A stent includes a cylindrical frame consisting of a series of helical winds containing a pattern of alternating zigzag bends. The frame may be made of resilient wire or from a piece of laser cut hypo tubing by placing the stent over a notched portion of a pusher catheter member, and retained on the pusher catheter member by a release wire threaded through the pusher catheter member and over the stent. The stent may also be deployed by placing the stent over a pusher catheter member having opposing notched portions, and retaining the stent and pusher catheter member in a delivery catheter, which can be withdrawn when stent reaches the site to be treated to release the stent.
