Abstract: A system SY for determining a tissue type TY of a tissue region TR is provided in which the distal ends OFDE1..n of at least three optical fibers define a plurality of intersecting optical paths IOP1..k within the tissue region TR. A tissue signal Q1..k indicative of a tissue type TY for the respective optical path IOP1..k is generated from said spectral measurement data SMD corresponding to each of the plurality of intersecting optical paths IOP1..k. Each tissue signal Q1..k is compared with a reference threshold QRT for the tissue type, and with an average of the tissue signals QMA. At least a portion of the tissue region is identified as the tissue type TY if i) every tissue signal Q1..k in the tissue region TR indicates that its corresponding tissue is not the tissue type TY in the comparison with the reference threshold QRT and ii) at least one of the tissue signals Q1..k in the tissue region TR lies between the average QMA of the tissue signals Q1..k and the reference threshold QRT, and a difference Δ between the at least one tissue signal Q1..k and the average QMA of the tissue signals Q1..k exceeds a predetermined value ΔP.

Abstract: The present invention relates to a method for determining a state of tissue sealing during a tissue sealing process. According to the disclosed method, an optical probe beam is used to irradiate a tissue region. A signal indicative of optical scattering in the tissue region is generated from a portion of the optical probe beam that has passed through or been returned by the tissue region. The onset of tissue sealing is indicated by the successive occurrence in time of a turning point and a point of inflection in the optical scattering signal. An energy-based tissue sealing or tissue-cutting device for use in accordance with the method is also disclosed.
