Patent Images
1. A radiopaque marker comprising:
- a core wire have a proximal portion and a distal portion, the core wire formed from a shape memory material; and
a coil wrapped around the distal portion of the core wire and coupled to the core wire,wherein at least one of the core wire and the coil is formed from a radiopaque material,wherein the core wire includes a delivery configuration wherein the core wire is substantially elongated and a deployed configuration wherein the distal portion of the core wire forms a substantially helical, tubular shape.

Abstract
A radiopaque marker includes a core wire having a proximal portion and a distal portion, and a coil wrapped around the distal portion of the core wire. The core wire is formed from a shape memory material and the coil is formed from a radiopaque material. The radiopaque marker includes a delivery configuration wherein the radiopaque marker is substantially elongated and a deployed configuration wherein the distal portion of the raadiopaque marker forms a substantially helical tube.

6. A method for visualizing a vessel comprising the steps of:
-
advancing a radiopaque marker in a delivery configuration endoluminally into the vessel, wherein the delivery configuration is a substantially elongate wire with a proximal portion and a distal portion, wherein the distal portion is radiopaque; deploying the radiopaque marker such that the distal portion forms a helical tube abutting walls of the vessel; and taking an image of the vessel with the radiopaque marker deployed therein. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A method for creating an in situ fenestration in a stent graft comprising the steps of:
-
advancing a radiopaque marker in a delivery configuration endoluminally into the branch vessel, wherein the delivery configuration is a substantially elongate wire with a proximal portion and a distal portion, wherein the distal portion is radiopaque; deploying the radiopaque marker such that the distal portion forms a helical tube abutting walls of the branch vessel; advancing endoluminally a stent graft into a primary vessel from which the branch vessel branches and deploying the stent graft in the primary vessel; advancing a puncturing device endoluminally through a lumen of the primary stent graft and adjacent the branch vessel; and advancing the puncturing device through a wall of the primary stent graft in a direction aligned with the orientation of the branch vessel. - View Dependent Claims (17, 18, 19)
