Abstract:
Ablation and visualization systems and methods to access quality of contact between a catheter and tissue are provided. In some embodiments, a method for monitoring tissue ablation of the present disclosure comprises advancing a distal tip of an ablation catheter to a tissue in need of ablation; illuminating the tissue with UV light to excite NADH in the tissue, wherein the tissue is illuminated in a radial direction, an axial direction, or both; determining from a level of NADH fluorescence in the illuminated tissue when the distal tip of the catheter is in contact with the tissue; and delivering ablation energy to the tissue to form a lesion in the tissue.

Claim (Index 14):
A system for monitoring tissue ablation comprising:\n a catheter comprising:\n a catheter body; and \n a distal tip positioned at a distal end of the catheter body; \n an ablation system in communication with the distal tip to deliver ablation energy to the distal tip; a visualization system comprising a light source, a light measuring instrument, and one or more optical fibers in communication with the light source and the light measuring instrument and extending through the catheter body to the distal tip, wherein the one or more optical fibers are configured to pass light to a tissue and collect light returned from the tissue; a processor in communication with the light measuring instrument, the processor being programmed to:\n receive data relating to the light returned from the tissue illuminated with the light from the light source; and \n determine a tissue composition of the tissue based on a spectral signature over a wavelength range of the light returned from the tissue by identifying at least one of a collagen peak indicative of an amount of collagen in the tissue and an NADH fluorescence peak indicative of an amount of myocardium in the tissue to determine a relative amount of collagen and myocardium in the tissue.
