  1. Katie Brown Bme 281 11/27/2012 Liver Dialysis: Molecular Adsorbents Recirculation System

  2. Problem Being Solved • Liver Failure is caused by: • Hepatitis B, Hepatitis C, Long term alcohol consumption, Cirrhosis, Hemochromatosis, Malnutrition, Acetaminophen (Tylenol) overdose, reactions to certain prescription and herbal medications, Ingestion of poisonous wild mushrooms • 2000 people die each year while waiting for a liver transplant

  3. History of Liver Transplants • 1728-John hunter, a Scottish surgeon, performed animal transplants and tooth transplants • 1890-Matheui Jaboulay discovers vascular anastomosis with everting sutures • 1901- Alexis Carrol implemented animal organ transplant using a triangulating vessel technique

  4. History (cont) • 1963-Tom Starzl performed the first liver transplantation • 1970’s-Starzl and other surgeons 100 executed transplantations with 30% success • 1996-Stanford split liver transplant • 2004- Germany has developed MARS – Molecular Absorbent Recirculating System

  5. Liver • Has many functions making it one of the most important organs in the body • processes digested food from the intestine controlling levels of fats, amino acids and glucose in the blood  • combating infections in the body  clearing the blood of particles and infections • manufacturing bile • stores iron, vitamins and other essential chemicals • makes enzymes and proteins

  6. Current State: Molecular Adsorbents Recirculation System, or MARS • The closest we are to a “artificial liver” • Cannot replace a liver, but is a bridge between liver failure and transplant • How it works • Transports a patient's blood to a filter • Mixed with a sticky protein called albumin. • Toxins in the blood attach to the albumin molecules, which then carry the poisons out of the blood

  7. Limitations • Is not permanent – do not replace liver • Only last for a short period of time • In hospital • May have complications-infections • Cost for a seven hour treatment € 300 for 600 ml human serum albumin solution (20%), € 1740 for a MARS treatment kit and € 125 disposables used by the dialysis machine have to be spent

  8. Future • More like a liver • Lower Cost • Longer lasting • Portable • “artificial liver”
