Abstract
Methods and systems for reduced temperature radiation sterilization of stents are disclosed.
Claims13
A system for sterilizing a stent-catheter assembly, the stent-catheter assembly including a stent, comprising:
- a cooling source;
- a barrier configured for scattering radiation to thereby produce a more uniform dose distribution;
- and
- a radiation source;
- wherein the system is arranged so that at least the stent is located adjacent the cooling source and the barrier is disposed between the stent and the radiation source.

A system for sterilizing a stent comprising:
- a container for holding a stent-catheter assembly including a polymer stent, wherein the container is capable of being sealed along an edge thereof, the container including
- on a first side thereof, a barrier configured to scatter radiation, and
- on a second side thereof, a cavity;
- wherein the system is configured for sterilizing the stent-catheter assembly at a sterilization temperature maintained by a cooling member received in the cavity, and
- wherein when the stent is exposed to radiation the barrier is disposed between a radiation source and the stent so as to increase the uniformity of dose received by the stent.
