"Condition of a medical device that is free from viable
microorganism".
In order to reach that state, medical devices must be cleaned and TERMINALLY
STERILIZED (term for medical devices which have been sterilized after being completely sealed or enclosed
in at least the primary (barrier) package...)
It is important to understand that there is NO universally applicable method to
TERMINALLY STERILIZE a packaged medical device:
different sterilization methods / principles / cycle designs are
available, but each of them has RESTRICTIONS, can so not be applied to all devices / packages
modern medical equipment is no longer "simple stainless steel"
but can be formed of a variety of different materials and designs (MIS-instruments; optics; high
density equipment like drilling machines...) : depending from the device, a suitable sterilization method /
packaging must de selected
different packaging materials / systems are available, offering different
levels of protection - but also different sterilization compatibility...
Validation required...
As a specific application (specific device in a specific packaging, exposed to a
specific sterilization cycle in the individual hospital) may be unique in a specific hospital, regulations require
that the HOSPITAL USER needs to validate sterilization compatibility of this combination.
