Patent ID: 8808271

Claim:
A medical or veterinary system comprising: a first module operable to remain in a digestive or respiratory tract of a subject for more than a day and to dispense a first therapeutic material responsive to a first device state and a second therapeutic material responsive to a second device state, the first module including at least: circuitry for obtaining at least one of optical or electrical measurement data; circuitry for transmitting the at least one of optical or electrical measurement data including at least an electrically conductive coil configured as an antenna; update implementation circuitry; circuitry for obtaining concentration-indicative measurement data; one or more releasable modules small enough to pass through a pylorus of at least one of the digestive or respiratory tract per vias naturales, at least one of the releasable modules including one or more of a sensor or a medication; one or more reservoirs containing at least an artificial marker and one or more of a hormone, an anti-inflammatory agent, or an antihyperglycemic medication; and one or more material flow paths extending from at least one of the one or more reservoirs; a second module comprising at least a first material flow conduit segment extending from the first module at least into a throat of the digestive or respiratory tract, a second material flow conduit segment extending from the first module at least into an esophagus of the digestive or respiratory tract, a third material flow conduit segment extending from the first module at least out of a gastric compartment of the digestive or respiratory tract, and a fourth material flow conduit segment extending from the first module at least into an intestine of the digestive or respiratory tract; and a remote module operable for receiving status-indicative data from the first module.
