Trans Medics has developed a technology to keep a donor's heart alive by pumping blood through it and feeding it nutrients so a transplant surgery no
longer has to be a race against the clock. Pretty amazing.
The video I'm going to link (it's not youtube so I couldn't get it on here) is indeed graphic so if you have a weak stomach you many want to
pass.
There's no telling how many lives this could possibly save in the future.
