Abstract
Systems, devices, methods, and compositions are described for providing an actively-controllable disinfecting implantable device configured to, for example, treat or prevent an infection in a biological subject.
Claims38
A medical device, comprising:
- a catheter device including a body structure defining one or more catheters, the body structure having an outer surface and an inner surface defining one or more fluid-flow passageways, at least a portion of the body structure including one or more self-cleaning surface regions;
- one or more selectively actuatable energy waveguides configured to direct an emitted energy stimulus to one or more regions proximate at least one of the outer surface or the inner surface of the body structure;
- one or more energy emitters configured to emit an energy stimulus, the one or more energy emitters operatively coupled to the one or more selectively actuatable energy waveguides;
- and wherein an average integrated flux of the one or more selectively actuatable enemy waveguides is less than about 80 milli-joules per square centimeter.
