New Artificial Heart Mixes Synthetic and Natural Materials
the MPR take:
Carmat, a biotechnology company, has announced the creation of a new artificial heart that is the first to mix synthetic and biological materials. The heart valves and membranes that come into contact with the patient’s blood are created from cow-heart tissues and the remainder is constructed from polyurethane. The biological materials are designed to prevent blood clotting that can occur when blood comes into contact with synthetic materials. This heart weighs approximately 2.2 pounds and is designed to last up to five years. This artificial heart can be used in patients who are waiting for or are not eligible for a human transplant; however, because it is larger than a normal human heart, it is not suitable for children and some women. So far two patients have received the heart transplant in a clinical trial, with two other patients expected to participate; the first test patient lived for 75 days.
Medical researchers are getting closer to creating whole, working human hearts. Organ transplantation—removing a piece of one person and sewing it into another—is one of the weirder things that humans have figured out how to do. The Carmat's first test patient received his heart this past ...
