In one embodiment, light is utilized to periodically illuminate tissues adjacent the cervix, the light being detected serving as an indicator of the onset of labor. The detection of a condition of premature labor is transmitted to a patient monitor through either conductors extending out of the body and into the monitor, or via electromagnetic transmissions (radio) sent from the pessary to a receiver associated with the patient monitor. Interpretation of the energy detected may occur either within the pessary or within the patient monitor. | |
