Abstract

A device for detection of changes in the tissue of various parenchymatous organs (1 ) comprising a spectroscope (2) with the spectroscopic probe (3), source (6) of near infrared radiation with connected light fiber (5) which contains on its other end the means (8) for directing light beam and than the means (7) for introducing the light fiber (5) and spectroscopic probe (3) into the examined organ (1). The device is applicable for effective and precise examination of the parenchyma.

Claims

AMENDED CLAIMS received by the International Bureau on 12 April 2010 (12.04.2010)
1. A device comprising spectroscope (2) with spectroscopic probe (3), the source (6) of near infrared radiation with connected optical fiber (5), the fiber (5) containing on its other ending the means (8) for directing the light beam and the means (7, 9) for introducing optical fiber (5) and spectroscopic probe (3) into an examined parenchymatous organ (1), for use in detection and monitoring of structural changes in a parenchyma tissue of a parenchymatous organ (1).
2. The device according to claim 1 wherein the optical fiber (5) ending equipped with the means (8) for directing light beam and the end of the spectroscopic probe are, after introducing optical fiber (5) and spectroscopic probe (3) into the examined organ (1), mutually positioned in a defined distance.
3. The device according claim 1 or 2 wherein the means (8) for light beam directing is a mirror.
4. The device according to any one of claims 1 to 3 wherein the means for introducing the light fiber (5) and spectroscopic probe (3) into the organ (1) is a hollow needle (7).
5. The device according to claim 4 wherein the hollow needle (7) comprises a side opening.
6. The device according to any one of claims 1 to 3 wherein the means for introducing light fiber (5) and spectroscopic probe (3) into the organ (1) is a flexible catheter (9).
7. A device comprising hyperspectral camera (11) with flexible endoscope (10), and the source (6) of near infrared radiation with connected optical fiber (5), wherein the fiber (5) passes through the working channel of the flexible endoscope (10), for use in detection and monitoring of structural changes in a parenchyma tissue of a parenchymatous organ (1).
8. A device comprising hyperspectral camera (11) with flexible endoscope (10), and the source (6) of near infrared radiation with connected optical fiber (5), wherein the fiber (5) is adapted for attaching externally to the surface of the body, for use in detection and monitoring of structural changes in a parenchyma tissue of a parenchymatous organ (1).
