This episode takes another look at biotribology, focusing on the heart. In the interview we talk with Dr. Said Jahanmir, President and CEO of MiTiHeart Corporation. Dr. Jahanmir has specialized in this area of research, which focuses on patients with congestive heart failure (CHF). CHF refers to a situation where a patient's heart cannot pump enough blood to meet the body's needs, and it affects 4.5 million people annually. This population sometimes requires medical intervention, and a blood pump is one source of that assistance.
Tribology is a necessary requirement when designing, creating, and implanting devices that assist the heart. If these issues are not considered, the pump could have adverse effects on the blood, tissues and the heart.
One type of blood pump, called an LVAD or left ventricular assist device, is in development at MiTiHeart. Dr. Jahanmir addresses the design, testing and impact that this LVAD will have. In the picture, you can see the relative size and shape of the LVAD.
