Abstract: The invention relates to electrodes used in ablation catheter devices, where the electrodes contain two or more thermal sensors at different positions within the electrode that are capable of detecting temperature differences along the external surface of the electrode. In preferred embodiments, the thermal sensors are separated by one or more thermal insulating members and the thermal sensors are positioned near the external surface of the electrode at about the same distance from the end of the electrode, so that temperature measurements can indicate the position of the electrode with respect to the tissue desired to be ablated.

Abstract: A system for displaying characteristics of target tissue during an ablation procedure is provided that includes an electronic control unit (ECU) configured to receive data regarding electrical properties of the target tissue for a time period. The ECU is also configured to determine a value responsive to the data and indicative of at least one of a predicted depth of a lesion in the target tissue, a predicted temperature of the target tissue, and a likelihood of steam pop of the target tissue for the time period. The system further includes a display device operatively connected to the ECU. The display device is configured to receive the value and display a visual representation indicative of at least one of a predicted depth of a lesion in the target tissue, a predicted temperature of the target tissue, and a likelihood of steam pop of the target tissue for the time period.

Abstract: A method for projecting a 3D surface geometry onto a planar projection comprises: obtaining a 3D geometry of a chamber surface using an algorithm that generates angles and distances between points on the chamber surface that represent mapping information; applying a cutting curve to at least two points on the chamber surface; and at least partially unfolding at least a portion of the chamber surface along the cutting curve to form a planar projection that optimally preserves the angles and distances between points on the chamber surface.

Abstract: A system for controlling delivery of ablation energy by an ablation catheter to tissue in a body is provided. The system includes an electronic control unit configured to determine, responsive to a measurement signal from the ablation catheter, a value for a characteristic associated with the delivery of ablation energy to the tissue. In one embodiment, the characteristic is the degree of contact between the ablation catheter and the tissue. The unit is further configured to generate a control signal, responsive to the determined value of the characteristic, to control an amount of energy delivered from an ablation delivery element on the ablation catheter to the tissue. The amount of energy varies in response to the determined value of the characteristic when the determined value of the characteristic meets a predetermined condition relative to a threshold value for the characteristic.
