Abstract

The present invention relates to an elongate, flexible, medical device comprising: an elongate, flexible inner member; a support member extending around the inner member; a plurality of electrically-conductive wires, each being braided with the support member; an outer member; and at least one ionic electroactive polymer actuator, the actuator comprising: at least one polymer electrolyte layer secured adjacent to the distal end of the inner member; and a plurality of electrodes circumferentially distributed about the exterior surface of the at least one polymer electrolyte layer, wherein at least one of the plurality of electrically-conductive wires, adjacent to the distal end thereof, is electrically connected to one of the electrodes, and the at least one polymer electrolyte layer is configured to deform asymmetrically in response to the application of an electrical signal through at least one of the plurality of electrically-conductive wires to at least one of the plurality of electrodes.
