Abstract
A radiotherapy stent device has a flexible, collapsible mesh body that can be expanded in a blood vessel of a patient to deliver radiation to the tissue surrounding the site of stent implantation. One or more hollow sleeves are secured on the body. The sleeves are loaded with radioactive material immediately prior to positioning of the stent in the vascular structure. As a result, the shelf life of the stent is substantially increased, and dosage of the radiation can be more precisely controlled.
