Abstract

A method and system for assessing lesion formation in tissue is provided. The system includes an electronic control unit (ECU) configured to acquire magnitudes for a component of a complex impedance between an electrode and tissue, and the power applied to the tissue during lesion formation. The ECU is configured to calculate a value responsive to the complex impedance component and the power. The value is indicative of a predicted lesion depth, a likelihood the lesion has reached a predetermined depth, or a predicted tissue temperature. The method includes acquiring magnitudes for a component of a complex impedance between an electrode and tissue and the power applied during lesion formation. The method includes calculating a value responsive to the complex impedance component and the power, the value being indicative of a predicted lesion depth, a likelihood the lesion has reached a predetermined depth, and/or a predicted tissue temperature.

U.S. Classification

600586, 606 42

Abstract

A system that automatically detects a myocardial barotrauma (i.e., tissue pop) event so that proper post-procedure care can be given includes an electronic control unit (ECU), a computer-readable memory coupled with the ECU, and detection logic stored in the memory configured to be executed by the ECU. The detection logic is configured to receive a signal generated by an electro-acoustic transducer related to acoustic activity within the patient, monitor the signal for a pre-determined indication of a barotrauma event, and output a notification when the pre-determined indication is detected. The transducer can be integrated with an extra-body patch that includes one or more electrodes for use with a medical device navigation system.

International Classification

A61B 34/10, A61B 34/00, A61B 18/12, A61B 18/12

Abstract

A method for determining a predicted lesion size formed in a tissue by receiving or calculating a measure of contact force between the electrode and the tissue, determining a tissue characterization, and calculating the predicted lesion size using both the measure of contact force and the tissue characterization. A system comprising an electronic control unit configured to receive or determine a measure of contact force between the electrode and the tissue, characterize the tissue based on both the measure of impedance and the measure of contact force, and cause the tissue characterization to be either (a) presented to a user, or (b) applied to calculate a metric and cause the metric to be presented to the user.
