1. A monitoring device comprising:
- a needle assembly having a needle body, said needle body having an open back end and a pointed tip end and having a sidewall defining a long-narrow lumen extending between said open back end and said pointed tip end, said sidewall further defining at least three side ports;
a fiber optic bundle disposed in said lumen and in communication with said ports;
a radiation delivering fiber optic element disposed in said lumen and in communication with at least one of said ports;
a radiation source in communication with said radiation delivering fiber optic member for irradiating an area adjacent said at least one of said ports;
at least one return fiber optic element in communication with the remaining side ports;
a light detector in communication with said return fiber optic elements for receiving radiation from an irradiated area.

Abstract
A needle with fiber optic capability for spectrophotometric analysis includes a needle assembly including a needle body having an open tip and side radiation ports. A fiber optic element is disposed in the needle assembly for carrying electromagnetic radiation to the open tip area for transmission to a target area. Fiber optic bundles in communication with the radiation ports are disposed in the needle body for transmitting backscattered radiation to a light detector or sensor for spectrophotometric analysis. The needle assembly may include barbs for anchoring the device in place.

22. A method of detecting or monitoring a physiological condition or biological phenomena with spectrophotometry comprising:
-
securing a needle body having a fiber optic bundle disposed therein in an area to be spectrophotometrically analyzed; irradiating at least one fiber optic member of said bundle with electromagnetic radiation for delivery to said area through a plurality of ports in said needle body; receiving backscattered radiation through additional ports in said needle body and transporting said radiation to a light detector; and communicating a signal from said light detector to a sensor configured to decipher a value from said signal. - View Dependent Claims (23)
