Indwelling Fiber Optic Probe for Blood Glucose Measurements
First Claim
1. An indwelling fiber optic probe, comprising at least one optical fiber having a proximal end and a distal end, wherein illumination light from a near-infrared light source is coupled into the proximal end and directed to the distal end of the fiber and wherein the distal end is inserted into a patient tissue and wherein light from the tissue is collected by the distal end of the at least one optical fiber and returned to the proximal end of the fiber as collected light.

Abstract
An indwelling fiber optic probe can be used to make in vivo blood glucose measurements through a central venous catheter. The fiber optic probe can operate in the near-infrared spectral region. The optical measurement can be backscattering, transmission, or a combination of both, depending on the optical configuration.
