Abstract

Radiopaque marker elements for attachment to ends of a radially expandable surgical stent are disclosed. Each radiopaque marker element is homogeneously formed from a radiopaque material and attached through an attachment means to ends of the stent. The radiopaque marker elements enhance the visibility of the stent when the stent is viewed with a medical imaging device, such as a fluoroscope. The marker elements extend beyond ends of the stent. The marker elements are attached to the stent before radial expansion and are configured to radially expand along with the stent during surgical implantation thereof within a body lumen, such as an artery. The radiopaque marker elements can either be attached to an unmodified radially expandable surgical stent or to a prepped stent which includes receivers at ends of the stent particularly configured to attach to the radiopaque marker elements. The radiopaque marker elements include tabs which match a contour of the receivers so that secure attachment of the radiopaque marker elements to the receivers at the ends of the stent is provided.
