First Claim
1. A method of fabricating a medical stent, comprising:
- (a) cutting a first cylinder of electrically conductive material so as to create a first pattern of conductive mesh strands having a plurality of nodes;
(b) cutting a second cylinder of electrically conductive material so as to create a first pattern of conductive mesh strands having a plurality of nodes;
(c) positioning the first cylinder into a volume of the second cylinder and positioning the first cylinder with respect to the second cylinder such the nodes of the first cylinder are close to the nodes of the second cylinder without the nodes of the first cylinder touching the nodes of the second cylinder; and
(d) applying a non-conductive binding material to adjacent nodes of the two cylinders.

Abstract
A medical device includes a pattern of electrically conductive material. The pattern of electrically conductive material has an anti-antenna geometrical shape such that the anti-antenna geometrical shape substantially prevents the medical device from creating an imaging artifact and/or substantially allows imaging of a volume within the medical device. The pattern may be formed by multiple “figure-8” shaped electrical conductors, multiple “figure-8” emulating electrical conductors, multiple sine-wave-like shaped electrical conductors, multiple zig-zag patterned electrical conductors, by multiple electrical conductors, each having sequential conductive loops, and/or a single conductor weaved into a loop mesh. The electrically conductive material may be titanium, tantalum, nitinol, stainless steel, and/or NbZr.
