Abstract
A medical device includes at least one ionic electroactive polymer actuator, the actuator including at least one polymer electrolyte member defining at least a surface and a plurality of electrodes disposed about the surface of the at least one polymer electrolyte member, an elongate, flexible portion defining a proximal end and a distal end secured adjacent to the ionic electroactive polymer actuator and the elongate, flexible portion further comprising a core and a sleeve surrounding the core and a plurality of electrically-conductive wires, each having a proximal end and a distal end coupled to at least one of the plurality of electrodes, wherein the at least one polymer electrolyte member deforms asymmetrically in response to the application of an electrical potential supplied through at least one of the plurality of electrically-conductive wires to at least one of the plurality of electrodes.
