Abstract
Abstract A system for treatment of tissue, such as heart tissue, includes a laser source and a catheter having an optical waveguide which is operatively connected to the laser source. The catheter also includes a position sensor for generating position signals relating to the distal end of the catheter and an electrode for generating signals relating to the viability of the tissue. The system also includes signal processing circuitry for processing the position signals in order to determine position coordinates of the distal end of the catheter as well as the signals relating to the viability of the tissue for determining a viability map of the tissue. The system further includes a display for displaying the viability map.
