Abstract: Medical apparatus includes one or more magnetic field generators, which are configured to generate magnetic fields within a body of a patient. An invasive probe includes an insertion tube having a distal end, which is configured for insertion into the body, and a plurality of flexible splines configured to be deployed from the distal end of the insertion tube. Each spline includes a flexible, multilayer circuit board and a conductive trace that is formed in at least one layer of the circuit board and is configured to define one or more coils, which are disposed along a length of the spline and output electrical signals in response to the magnetic fields. A processor is coupled to receive and process the electrical signals output by the coils in order to derive respective positions of the flexible splines in the body.

Abstract: A method for tissue assessment includes ablating tissue at a site within a body of a living subject using an invasive probe applied to the site. At a first stage in ablation of the tissue, first measurements are made of scattered light intensities from the site at a plurality of different wavelengths. At a second stage in the ablation of the tissue, subsequent to the first stage, second measurements are made of the scattered light intensities from the site at the plurality of different wavelengths. Progress of the ablation is assessed by computing different, respective measures of change in the scattered light intensities at the different wavelengths occurring between the first and second measurements, and comparing the respective measures.
