ABSTRACT:
A catheter comprises a first catheter shaft comprising a wall. The wall comprises at least one section of electroactive polymer having an actuated state and a non-actuated state and defines a first lumen. In the actuated state the first lumen haves a first diameter and in the non-actuated state the first lumen haves a second diameter, the first diameter being different than the second diameter.
