    摘要: The invention is a next generation miniature heart assist device which has been developed in order to maintain the blood circulation in patients with severe heart failure, and is applied endovascularly to the large arteries such as the assending aorta and/or the pulmonary artery. This device is technically a kind of synchronous servo electric motor using "direct drive technology". As it consumes much less energy because of its small volume and extraordinary design, it provides longer battery life and high blood flow. Small volume and very low energy consumption due to the unusual design of the engine in order to provide a much longer battery life and a high blood flow. As the outer surface of the parts placed into the blood vessel will be completely covered with the endothelial cells and the intima layer of the arteries in time, there will be no foreign surface contacting directly with blood. As a result, no thromboembolic event or any negative effect on the cellular components of blood is expected. The invention is a new generation heart assist device applied endovascularly to great arteries with its success and high reliability.
