Assignee: EFFERENT LABS, INC.
Field: Measurement (Instruments)
Classification: CPC A  G | IPC A  G

Claim 15:
16. An implantable apparatus for reporting a physiological measurement from within a host organism, the apparatus comprising:
a) a sample chamber that is configured for implanting within the host organism, the sample chamber having a measurement port and live cells, wherein the live cells are treated to fluoresce in response to illumination having an excitation wavelength and an illumination intensity;
b) an optical sensor housing that is configured for implanting within the host organism and that has a window and an optical chamber that is partitioned by a beam splitter into an excitation sub-chamber and a detection sub-chamber, wherein the excitation sub-chamber and the detection sub-chamber are optically and spatially separated by the beam splitter, and wherein both sub-chambers are in optical communication with the window, and wherein the optical sensor housing is energizable to generate the illumination, wherein the optical sensor housing is further configured to measure an emitted light from a sample, the emitted light having a fluorescent wavelength that is different from the excitation wavelength,
wherein a ratio of excitation illumination photons to detected emitted light photons exceeds 100,000 to 1,
wherein the optical sensor housing is further configured to transmit a wireless signal indicative of the measured emitted light;
and
c) a coupling that couples the measurement port of the sample chamber in a fixed position relative to the window of the optical sensor housing.
