Abstract

Abstract The invention provides apparatus and methods for mapping conduction pathways and creating lesions in the heart wall for the treatment of atrial fibrillation. The apparatus may include at least one epicardial ablation probe having a plurality of electrodes for creating a lesion. The apparatus and method facilitate the formation of a lesion which electrically isolates the pulmonary veins from the surrounding myocardium.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 107 words
A method of creating a continuous lesion in cardiac tissue, comprising the steps of: providing an ablating device having an ablated element and an elongate guide member; positioning the elongate guide member adjacent at a fixed position adjacen to cardiac tissue where a continuous lesion is desired; ablating tissue with the ablating element a number of times after the positioning step to create a plurality of lesions which together form the continuous lesion in the cardiac tissue; and moving the ablating element along the elongate guide member to a plurality of positions to create the plurality of lesion while the guide member remains in the fixed position.
Claim 2
Independent Claim 107 words
A method of creating a continuous lesion in cardiac tissue, comprising the steps of: providing an ablating device having an ablated element and an elongate guide member; positioning the elongate guide member adjacent at a fixed position adjacen to cardiac tissue where a continuous lesion is desired; ablating tissue with the ablating element a number of times after the positioning step to create a plurality of lesions which together form the continuous lesion in the cardiac tissue; and moving the ablating element along the elongate guide member to a plurality of positions to create the plurality of lesion while the guide member remains in the fixed position.
Claim 3
Dependent Claim 47 words
The method of claim 1 , wherein: the providing step is carried out with the ablating device having a locating device positioned adjacent the ablating element, the locating device locating a previous lesion formed by the ablating device while the guide member is in the fixed position.
Claim 4
Dependent Claim 22 words
The method of claim 1 , wherein: the providing step is carried out with the ablating device having first and second electrodes.
Claim 5
Dependent Claim 21 words
The method of claim 3 , further comprising the step of: measuring relative electrogram amplitude between the first and second electrodes.
Claim 6
Dependent Claim 20 words
The method of claim 3 , further comprising the step of: sending an electrical impulse with one of the electrodes.
