ABSTRACT:
A stent according to the systems and methods described herein may include a body formed from a non-radioactive structural material, a radiopaque material coating the body, and a beta-emitting radioisotope ion implanted into the radiopaque material. Optionally, an adhesion layer, such as titanium, vanadium, chromium, iron, cobalt, nickel, or some combination or alloy thereof, may be applied to the body to facilitate adhesion of the radiopaque material. The radiopaque material may include platinum, iridium, rhenium, gold, tantalum, or some combination or alloy thereof. The beta-emitting radioisotope may include sulfur-35 or phosphorous-32 and may be ion implanted into the radiopaque material.
