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.
Claims9
A catheter device, comprising:
- one or more sensors operable to detect in real time a microbial presence in one or more regions proximate the catheter device;
- a body structure having an outer surface and an inner surface defining one or more fluid-flow passageways, the body structure having one or more surface regions that are controllably actuatable between at least a first wettability state and a second wettability state;
- and
- an actively controllable excitation component configured to deliver, in vivo, an energy stimulus to one or more regions proximate at least one of the outer surface or the inner surface of the body structure based on detecting information indicating a presence of an infectious agent proximate the catheter device.
