Abstract
Systems and methods for facilitating assessment of a nature of contact between an electrode assembly of an ablation catheter and viable body tissue are disclosed herein. In some embodiments, a method comprises obtaining a first detected voltage between a first electrode and a second electrode, wherein the first and second electrodes are positioned along an electrode assembly of the ablation catheter, and wherein the first electrode is distal to the second electrode, obtaining a second detected voltage between the second electrode and a third electrode, the third electrode positioned proximal to the second electrode.
