Optoelectronic system and apparatus for connection to biological systems
| DWPI Title: Apparatus for detecting and/or treating tissue, has optical collector connected to proximal end of optical fiber, and power component arranged to receive external optical power from optical fiber through transparent bonding structure |
| Abstract: The present invention relates to a biological probe structure, as well as apparatuses, systems, and methods employing this structure. In particular embodiments, the structure includes a hermetically sealed unit configured to receive and transmit one or more optical signals. Furthermore, the structure can be implanted subcutaneously and interrogated externally. In this manner, a minimally invasive method can be employed to detect, treat, and/or assess the biological target. Additional methods and systems are also provided. |
| Use: Apparatus for detecting and/or treating a target region i.e. tissue of a subject i.e. human. Uses include but are not limited to neural tissue, neural fascicles, subcutaneous tissue, muscle, nerve, peripheral nerve, and central nerve. |
| Advantage: The apparatus provides an implantable, completely insulated system that does not expose any non-beneficial electrical connections to a tissue, either on external surfaces or encased within polymeric substrates of a system. The apparatus patterns a medial surface of an active structure with windows in an opaque material with an optional anti-reflection coating to minimize optical coupling loss between a connector and receivers. The apparatus transmits an optical signal through a window and not a surrounding opaque material, thus minimizing losses due to structural misalignment and mismatches in cross-sectional areas and a numerical aperture. |
| Novelty: The apparatus (100) has a hermetically sealed unit comprising a signal processor circuitry arranged on a substrate and coupled to emitters and detectors, and comprising a power component arranged on the substrate and receiving external optical power and providing internal electrical power for use by other elements arranged on the substrate. An optical collector (110) is connected to a proximal end of an optical fiber. The power component is arranged to receive the external optical power from the optical fiber through an optically transparent bonding structure. |
