Abstract
A peristaltic pump for conveying a fluid comprises a flexible tube having an outer surface and a lumen for carrying the fluid such as a therapeutic agent. The tube has a length defined by opposed ends of the tube, the outer surface of the body carrying a plurality of longitudinally spaced-apart electroactive polymer actuators. The plurality of actuators are adapted to be responsive to electrical signals for energizing the actuators sequentially along the length of the tube to move a lumen pinch-off along the length of the tube to thereby convey the fluid from one end of the tube to the other end by means of a peristaltic pumping action. The peristaltic pump may be incorporated into a medical lead, such as an endocardial pacing lead, carrying at least one electrode.
