Abstract: An ablation catheter is provided for ablating internal tissue of a patient. The catheter includes a distal end that is adapted to be inserted into a body cavity relative to a desired location therein (e.g., within the heart). An ablation electrode is connected relative to the distal end of the catheter for providing ablation energy to patient tissue. A heat sink is provided that is in thermal contact with the ablation electrode. The heat sink, in addition to being in thermal contact with the ablation electrode, is electrically isolated from the ablation electrode. This allows the heat sink to conduct heat away from the ablation electrode without dissipating electrical energy from the electrode. In this regard, the heat sink may prevent build-up of excess heat within the electrode that may result in blood coagulation and/or tissue charring.

Abstract: An electrode head is disclosed that utilizes electrically conductive or dissipative fabric to exchange electrical energy with tissue. This electrode head may be used for any appropriate application, such as a catheter electrode, a return electrode, or the like. Any appropriate function may be provided by this electrode head, such as tissue ablation, tissue mapping, or providing an electrical ground.

Abstract: A method of generating a diagnosis map of at least a portion of the heart includes inserting an electrode within the portion of a heart, robotically moving the electrode therein, measuring electrophysiology information at a point on the surface of the heart, associating the measured electrophysiology information with position information for the point on the surface of the heart, repeating the measuring and associating steps for a plurality of points on the surface of the heart, thereby generating a plurality of surface diagnostic data points, and generating the diagnosis map therefrom. The electrode may be moved within the heart randomly, pseudo-randomly, or according to one or more predetermined patterns. A three-dimensional model of the portion of the heart may be provided and presented as a graphical representation, either with or without information indicative of the measured electrophysiology information superimposed thereon.
