Latest Patents

Among his latest patents, Ronald A. Ness has developed a ventricular assist device with minimal blood contacting surfaces. This device includes a pair of valved conduits and a pumping portion that connects to the circulatory system of a host patient. The design minimizes the number of material-surface transitions that blood must cross, thereby reducing the risk of complications. The valved conduits feature porcine xenograft valves, which are supported by a stenting structure located outside the blood-contacting flow path. Additionally, the inner wall member of the conduits is designed to be impervious to blood while allowing for a stable biological interface to form. This innovative design also includes sinuses that enhance valve action by creating vigorous vortices in the blood flow, effectively preventing clot formation.

Another notable patent by Ness is the ventricular assist conduit with externally supported tissue valves. Similar to his previous invention, this device aims to minimize blood-surface interactions and improve overall device performance. The incorporation of porcine xenograft valves and a flexible inner wall member further exemplifies his commitment to advancing medical technology.
