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 plurality of alternating notches and tubular shoulder portions formed in a side of the pusher catheter member, each of said notches receiving a plurality of the plurality of helical windings; and
a release wire removably threaded through the lumen of the pusher catheter member under said shoulder portions and over said plurality of the plurality of helical windings to retain the plurality of helical windings on said notched portion of said pusher catheter member, said release wire being capable of being withdrawn from said notched portion of said pusher catheter member when the intravascular flow modifier and reinforcement device is positioned at the site in the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 to release and deploy the intravascular flow modifier and reinforcement device at 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opposing notched portions, and retaining the stent and pusher catheter member in a delivery catheter, which can be withdrawn when stent reaches the site to be treated to release the stent.

20. 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 at least five alternating notches and tubular shoulder portions formed in a side of the pusher catheter member, each of said notches receiving more than one of the plurality of helical windings; a delivery catheter, and 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 can be withdrawn along with said release wire 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; and a release wire removably threaded through the lumen of the pusher catheter member under said shoulder portions and over each of said plurality of helical windings to retain said plurality of helical windings on said notched portion of said pusher catheter member, said release wire being capable of being 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 to release and deploy the intravascular flow modifier and reinforcement device at the site in the patient'"'"'s vasculature to be treated.
