Abstract
A sterile device immersed in a sterile buffer and a method for providing same. The sterile device may be a medical device such as a biosensor having a biomolecule as a sensing element such as, for example, a glucose oxidase enzyme. The buffer may be a bicarbonate solution. Both the device and the buffer may be packaged and stored over long term while maintaining sterilization. The sterilization method may comprise a combination of gaseous, liquid and light sterilization.
Claims8
A method of making a sterile, implantable medical device for in vivo implantation comprising:
- arranging an electronic circuit on a substrate;
- sterilizing the electronic circuit and the substrate with a first sterilization technique to provide a sterile electronic circuit and a sterile substrate;
- arranging a reservoir on the sterile substrate;
- arranging a biological molecule in the reservoir, the biological molecule for use as an agent in generating a signal to be used by the sterile electronic circuit;
- then
- sterilizing the biological molecule with a second sterilization technique, which is a different type of sterilization technique from the first sterilization technique, to provide a sterile biological molecule.
