Title: Innovations by David Richens
Introduction
David Richens is an accomplished inventor based in Nottingham, GB. He has made significant contributions to the field of medical devices, particularly in the development of innovative actuators and blood pumps. With a total of 2 patents, Richens has demonstrated his expertise and commitment to advancing technology in healthcare.
Latest Patents
Richens' latest patents include groundbreaking inventions such as electroactive actuators and a pulsatile blood pump. The electroactive actuators are designed for use in pumping fluids and applications requiring contractile actuation. These actuators utilize electroactive polymeric materials, particularly for vascular pulsation devices like variable aortic tension devices. The actuator features an inner tubular structure surrounded by an outer tubular structure made of dielectric elastomeric material, which contracts radially upon receiving an actuation voltage signal.
The pulsatile blood pump is another remarkable invention by Richens. This device is intended for implantation into patients and consists of a tubular body, a flexible membrane, and a port. The tubular body replaces a resected portion of a blood vessel, allowing blood to flow through a passageway. The flexible membrane creates a fluid chamber that separates from the blood passageway, enabling the pump to effectively move blood by adjusting the volumes of the fluid chamber and blood passageway.
