Catheter Insert with Optical Fiber for Raman Signal Measurement

Abstract

In one embodiment, an apparatus includes a catheter insert that includes a catheter connector and a sheath having a substantially cylindrical shape. The catheter insert is configured to be coupled to a catheter that includes a mating connector and a catheter tube, where at least a portion of the sheath is configured to be inserted into the catheter tube, and the catheter connector is configured to be connected to the mating connector. The apparatus also includes an optical fiber that includes an end face, where at least a portion of the optical fiber is contained within the sheath. The optical fiber is configured to transmit a pump-Stokes beam of light along the optical fiber to the end face, where the pump-Stokes beam is emitted from the end face and directed to a sample.
