Claims7

- exposing the stent delivery assembly to radiation from a radiation source, wherein a radiation barrier located behind a selected section of the stent delivery assembly selectively modifies the radiation from the radiation source that is delivered to the selected section of the stent delivery assembly;
- wherein the radiation barrier modifies the radiation by backscattering of radiation at the selected section;
- wherein the selected section receives a delivered dose that satisfies a required sterility assurance level (SAL).
