Abstract:
1. A lumenally-active device, comprising: a structural element configured to fit entirely within a body lumen, wherein the body lumen is at least a portion of a nostril, nasal cavity, respiratory tract, or oral cavity of an organism, the structural element including: a lumen wall engaging portion and a fluid contacting portion configured to contact fluid within the body lumen; a sensor on the structural element, the sensor configured to fit entirely within the body lumen and capable of detecting a presence of a material of interest that is at least one of dissolved or suspended in the fluid; response initiation circuitry on the structural element, the response initiation circuitry configured to fit entirely within the body lumen and operatively connected to the sensor and configured to generate a response initiation signal upon detection of the presence of a material of interest in the fluid by the sensor; and an active portion on the structural element, the active portion configured to fit entirely within the body lumen and operatively connected to the response initiation circuitry and capable of producing a response upon receipt of the response initiation signal, the response including releasing energy to modify or destroy the material of interest within the fluid.
