Introduction
Medical devices designated “STERILE” are prepared using appropriate and validated methods. Whenever
possible, sterile medical devices are terminally-sterilized using a properly validated and controlled
sterilization process (see EN 556-1, EN ISO 11135, EN ISO 11137-1, EN ISO 14160, EN ISO 14937,
EN ISO 17665, EN ISO 20857 and EN ISO 25424). When a medical device is intended to be sterile but
cannot be terminally sterilized, aseptic processing is the method of manufacture (see EN ISO 13408-1).
Aseptic processing necessitates that either:
a) the entire product is sterilized and then introduced into a sterilized package; or
b) components of the product are sterilized, then further processed/assembled, and the final product
packed into a sterilized package.
Processing/assembly and packaging are carried out in a manner that minimizes the opportunity for items
to become re-contaminated by carrying out these operations in a controlled environment in which
microbial and particulate levels are maintained at or below defined limits and human intervention is
minimized.
