Abstract
A method and device to correctly orient an intracranial occlusion device, such as a stent having differential porosity, with respect to desired areas of greater or lesser blood flow (e.g., branch vessels and aneurysms, respectively), said device being particularly adapted for use in treating aneurysms in intracranial or other tortuous vasculature. An intravascular device comprising a delivery catheter having a hub and angular lumen capable of constraining a pusher wire within a packaging catheter to deploy said stent in an orientation wherein the area of least porosity abuts the aneurysm, and area of maximal porosity permits blood flow to a branch or other vessel. A method of using same.

1-70. (canceled)
An intravascular system configured for insertion into a blood vessel, the intravascular system comprising:
- a delivery catheter defining an inner lumen, the inner lumen having a first non-circular configuration;
- and
- a pusher configured for insertion into the inner lumen of the delivery catheter, the pusher having a second non-circular cross-sectional configuration configured to allow axial movement within the lumen of the delivery catheter and to inhibit rotation of the pusher within the lumen of the delivery catheter to thereby maintain a pre-determined angular orientation of the pusher within the delivery catheter.
An intravascular configured for insertion into a blood vessel, the intravascular device comprising:
- a delivery catheter defining an inner lumen;
- a pusher configured for axial movement through the inner lumen of the delivery catheter;
- and
- a stent secured to the pusher such that the stent is deployable within the blood vessel via axial movement of the pusher through the delivery catheter, the inner lumen of the delivery catheter and an outer wall of the pusher having cross-sectional configurations such that rotation of the pusher is limited within the inner lumen of the delivery catheter upon insertion of the pusher into the delivery catheter to thereby maintain a pre-determined angular orientation of a stent secured to the pusher to enable desired radial placement of the stent.
