Abstract
An elongate, flexible, medical device having distal and proximal ends, including an inner member having a proximal and distal end, a support member extending around the inner member between the proximal and distal end, a plurality of electrically-conductive wires, each braided with the support member having a proximal and distal end, an outer member surrounding the inner member, the support member, and the plurality of electrically-conductive wires and an actuator including a polymer electrolyte layer secured adjacent to the distal end of the elongate, flexible inner member and defining an exterior surface, electrodes distributed about the exterior of the polymer electrolyte layer. The distal end of one of the electrically-conductive wires is electrically connected to one of the electrodes. The polymer electrolyte layer is configured to deform asymmetrically in response to the application of an electrical signal through the plurality of electrically-conductive wires to the plurality of electrodes.
