Abstract

The invention concerns a method of providing a stent with a radiopaque marker comprising the steps of: i) providing in the stent a radiopaque marker carrier portion; ii) sleeving the carrier portion with radiopaque material, with an insulating surface between the carrier and the marker material, and iii) plastically deforming material within the sleeve of radiopaque material, to secure the sleeve on the carrier portion. The invention further concerns a stent with a radiopaque marker, the stent exhibiting a generally annular form with luminal and abluminal major surfaces, the marker also exhibiting opposed major luminal and abluminal surfaces characterized in that i) the marker envelops a carrier portion of the stent and is electrically insulated from it; ii) portions of the material of the marker which exhibit evidence of plastic deformation secure the marker on the carrier portion.
