Lumenally-active device

摘要

Embodiments of a lumenally-active system and method of use and control thereof are disclosed. According to various embodiments, a lumenally-active device is positioned in a body lumen of an organism, where the device may sense a parameter of a fluid in the body lumen and perform an action on the fluid. Control logic and/or circuitry may be located on the device, or the system may include a separate control module. Liquid or gaseous fluids may be treated by embodiments of the device. Actions may include, for example, modification of a body fluid by addition or removal of a material, or by modification of a property of a body fluid or a component thereof.

主权项

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.
