Ablation catheter to generate linear lesions in heart muscle; has catheter body with linear, cylindrical ablation electrode and at least one insulated sensing electrode

摘要

The catheter has a catheter body (1) with a linear, cylindrical ablation electrode (3) at its distal end. At least one sensing electrode (6,7) is embedded in the cladding of the ablation electrode and is insulated from it. Preferably, the sensing electrodes are formed as narrow ring electrodes. Preferably, there are at least two sensing electrodes, which are spaced and insulated from each other and the ablation electrode.
