Medical Knitting

Hi all!! I am looking for some medical knitting. I found the following.

Knitted DNA
Knitted digestive system
Uterus
Breasts
Stump Sock
Stoma cover (a stoma is a device in the neck to assist ones breathing)

I know there are chemo caps as well, I have found lots of patterns for those.

I am looking for unique or useful things such as what is listed. If you know of any patterns, please do share or if you have any suggestions maybe i can come up with a pattern (wow CC look at me getting brave, you're rubbing off, lol)
