ELAD ARTIFICIAL LIVER
ELAD artificial liver to keep patient
alive temporarily by Vital Therapies Inc.
ELAD, or Extracorporeal Liver Assist
Device resides outside the body.
Mimicking a normal liver, it cleanses
the blood of toxins and waste, and
produces albumin and clotting factors.
It's not all artificial, though, with the
secret sauce inside being
"immortalized human liver cells,"
interlaced with tiny tubes through
which the patient's blood flows.
HEPALIFE: A BIOARTIFICIAL LIVER
Boston company HepaLife is working
on a "bioartificial" liver using a
proprietary line of liver stem cells.
Once the patient's blood is separated
into plasma and blood cells, a external
bioreactor unit with those stem cells
inside can reduce levels of toxic
ammonia by 75% in less than a day.
