Filed:

Dec 30, 2005

Appl. No.:

11/322591

Inventors:

Eduardo Jimenez - Paramount CA, US

Assignee:

Biosense Webster, Inc. - Diamond Bar CA

International Classification:

A61B 18/14

US Classification:

606 34, 606 41

Abstract:

The present invention is directed to a system, a method and a catheter that provide improved ablation capabilities and improved energy efficiency by selectively energizing catheter electrodes on the basis of impedance measurements. In particular, the invention is directed to the selective energization of catheter radial electrodes that together with a tip electrode form a generally continuous tissue contact surface, wherein the selection is made on the basis of impedance measurement as an indication of the amount of tissue contact of each radial electrode.

International Classification:

A61B 18/14

US Classification:

606 42

Abstract:

An electrophysiologic catheter with an improved control handle is provided. The catheter includes a heat transfer assembly to better dissipate heat in the control handle. The heat transfer assembly includes a pump, a reservoir containing a coolant, a heat transfer member, and a coolant transport network transporting coolant between at least the reservoir and the heat transfer member. In one embodiment, the heat transfer member is located within the control handle as a heat exchanger on the circuit board to receive the coolant for transferring heat from the integrated circuits to the coolant. In another embodiment, the heat transfer member is located on the circuit board directly surrounding the integrated circuits to internally cool the integrated circuit within the control handle. A second heat transfer member is located outside of the control handle as a heat exchanger.

Eduardo Jimenez - Fullerton CA, US
Kristine B. Fuimaono - Costa Mesa CA, US

International Classification:

A61B 18/12
A61B 18/14

Abstract:

An ablation system observes and monitors ablation parameters, including temperature, impedance, and/or the system's own closed-loop response to these ablation parameters in delivery of power to one or more ablation electrodes, including cessation of power delivery to one or more electrodes while maintaining power delivery to one or more other electrodes. The system comprises a catheter with one or more electrodes and a detection circuitry configured to detect an ablation parameter for each electrode, a controller coupled to the catheter, the controller having a processing unit and a memory storing instructions that, when executed by the processing unit, cause the processing unit to: receive a detected ablation parameter for each electrode from the detection circuitry, control a power supplied to each violating electrode to have a reduced power when the respective detected ablation parameter violates a defined ablation parameter, detect a rate of power reduction for each violating electrode, and stop the power supplied to each violating electrode when a respective detected rate of power reduction exceeds a threshold rate of power reduction.
