1. A catheter device, comprising:
- a body structure defining one or more fluid-flow passageways;
one or more acoustically actuatable electromagnetic energy waveguides configured to direct an emitted energy stimulus to one or more regions proximate at least one of an outer surface or an inner surface of the body structure; and
one or more energy emitters operatively coupled to the one or more acoustically actuatable electromagnetic energy waveguides,wherein the one or more acoustically actuatable electromagnetic energy waveguides are configured to exhibit a change to a refractive index in the presence of an acoustic stimulus.
