Patent ID: 7972371

Claim:
A magnetic resonance compatible stent for use in intravascular therapy, the stent comprising: a plurality of electrically conductive elements arranged in a generally tubular structure, the conductive elements comprising generally diagonally arranged struts with respect to a central axis of the stent to define a diamond-shaped mesh of the conductive elements, the conductive elements comprising: a plurality of zig-zag loops disposed about a central axis of the stent; and a plurality of linking members for joining the loops such that the loops and linking members form a generally tubular diamond-shaped conductive mesh cylinder around the central axis of the stent; and a plurality of non-conductive connector nodes disposed among the conductive elements for directing currents induced by RF signals in an examination region of a magnetic resonance apparatus to flow in the conductive elements such that the currents flowing in adjacent conductive elements cancel each other and a net current flowing in the stent is substantially minimized; wherein the loops and linking members are connected within the non-conductive connector nodes such that the current flowing through adjacent loops substantially cancel each other.
