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.
Claims28
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;
- 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;
- and
- at least one optical router operably coupled to at least one of the one or more energy emitters, the optical router configured to guide an energy stimulus based on one or more selection rules.

2 more elements
A catheter device, comprising:
- a body structure having an outer surface and an inner surface defining one or more fluid-flow passageways, the body structure including one or more selectively actuatable energy waveguides extending over a portion of a surface of the body structure, the one or more selectively actuatable energy waveguides configured to direct an emitted energy stimulus from one or more energy emitters to one or more regions proximate the surface of the body structure;
- at least one optical router operably coupled to at least one of the one or more selectively actuatable energy waveguides, the optical router configured to guide an energy stimulus based on one or more selection rules;
- one or more sensors configured to detect a spectral property associated with the presence of a microbial colonization in the one or more regions proximate the surface of the body structure;
- and
- one or more switches associated with one or more selectively actuatable energy waveguides, the one or more switches configured to establish or interrupt a connection between the selectively actuatable energy waveguides and respective one or more energy emitters.
