Patent ID: 8078251

Claim:
A transvaginal sensor for measuring one or more blood analyte levels or one or more hemodynamic parameters in a tissue-under-test, comprising: a light emitter for delivery of light to a tissue-under-test, a photodetector for reception of light from the tissue-under-test, a sensor body, a needle attached to the sensor body designed to adhere the sensor body to the tissue-under-test, the needle housing one of the light emitter for subcutaneous delivery of light to the tissue-under-test or the photodetector for subcutaneous reception of light from the tissue-under-test, a deployable member housing the other of the light emitter to deliver light to the tissue-under-test or the photodetector to receive light from the tissue-under-test, the deployable member movably attached to the sensor body, the other of the photodetector or light emitter housed in the deployable member set at a distance from the one of the photodetector or light emitter housed in the needle that is greater than a distance from any point on the tissue-under-test contacting surface of the sensor body to the photodetector or light emitter housed in the needle when the sensor is in a deployed state, and a plurality of conductors for conducting signals to the light emitter and from the photodetector.
