A catheter device for the delivery of one or more therapeutic agents comprising: a proximal end portion coupled to a controller configured to provide electrical signals; and a distal end portion comprising one or more electroactive polymer actuators configured for vibrational motion in response to the electrical signals; wherein the catheter device is configured to carry the electrical signals from the controller to the one or more electroactive polymer actuators; and wherein the catheter device is further configured to release one or more therapeutic agents from the distal end portion of the catheter device. The present disclosure also relates to a catheter device comprising a sleeve positioned over the electroactive polymer actuators. The present disclosure further relates to methods and procedures using devices and systems comprising electroactive polymer actuators.
