1. An implantable medical device, comprising:
an elongate member made from a material comprising an alloy containing rhenium in combination with zirconium and/or hafnium;
wherein the elongate member forms a part of a braid having a cross-section with a width W and a thickness T when the braid is unconfined outside a tube, wherein a ratio of W/T is equal to or greater than 2, wherein the braid is configured to roll up so that the cross-section of the braid has a collapsed width W′ when the braid is inside the tube, and wherein the collapsed width W′ of the cross-section when the braid is inside the tube is less than the width W of the cross-section when the braid is outside the tube.
