1. A catheter device, comprising:
- a body structure having an outer surface and an inner surface defining one or more fluid-flow passageways;
a plurality of selectively actuatable energy waveguides configured to direct an emitted energy stimulus to one or more regions proximate at least one of the outer surface and the inner surface of the body structure; and
one or more energy emitters configured to emit an energy stimulus, the one or more energy emitters operatively coupled to the plurality of selectively actuatable energy waveguides.

180. A system, comprising:
-
a body structure having an outer surface and an inner surface defining one or more fluid-flow passageways; a plurality of independently addressable energy emitting components disposed along a longitudinal axis of the catheter device, the plurality of independently addressable energy emitting components configured to direct an emitted energy stimulus to one or more regions proximate at least one of the outer surface and the inner surface of the body structure; and circuitry configured to determine a microorganism colonization event in one or more regions proximate at least one of the outer surface and the inner surface of the body structure. - View Dependent Claims (182, 191, 205)
