By combining synthetic and biological materials, researchers hope to create a safer and more effective artificial heart for patients awaiting transplants.
The heart, developed by Carmat, is made up of two chambers divided by a membrane. Hydraulic fluid is moved in and out of the chambers by a motorized pump, which causes the membrane to move and blood to flow through either side. The side of the membrane facing the blood is made from tissue from a cow’s heart, making the device more biocompatible and perhaps lessening the patient’s reliance on anti-coagulation medications.
The heart also uses valves made from cow heart tissue and sensors made by man to detect increased pressure within the device, which allows the internal control system to adjust the blood flow rate as needed.
