Abstract: In an embodiment, a method of producing a radiopaque stent graft is provided. The method may include functionalizing a surface of a coating layer of a stent graft to produce a functionalized surface; disposing a tie layer over the functionalized exterior surface of the stent graft; disposing an adherent layer over the tie layer; etching a slot into the adherent layer; functionalizing the slot; and positioning a radiopaque marker in the slot to produce a filled slot and thereby produce the radiopaque stent graft.

Abstract: A balloon catheter, and method of making the same, which includes an elongated shaft, and an expandable member affixed to the distal portion of the elongated shaft such that a section of the elongated shaft extends through at least a portion of the expandable member. The elongated shaft includes a radiopaque portion that includes a radiopaque material disposed in a non-metallic coating material. In some embodiments, the radiopaque portion is positioned adjacent the expandable member such that the position of at least a portion of the expandable member (or a stent disposed thereon) can be identified or determined within the vasculature in which it is deployed using an appropriate imaging technique, such as fluoroscopy. Additionally, in some embodiments, the radiopaque portion can define one or more raised areas on the elongated shaft adjacent the expandable member. In such embodiments, the raised area or areas in the radiopaque portion can function as mounting bodies for mounting a stent.
