Title:
絶縁電極中に輪郭が付与された開口部を有するアブレーションカテーテル
Document Type and Number:
Japanese Patent JP2009500073
Kind Code:
A
Abstract:
An array of ring electrodes or a wire electrode is mounted about the outside surface of the distal end of the ablation catheter. Substantially all of the outer surface of each ring or wire electrode is covered by an electrically insulating coating. The insulating surface coating on each ring defines a contoured opening in the insulating surface coating that exposes the conductive band or wire beneath. An array of contoured openings are formed along a wire electrode. The insulating coating mitigates potential edge effects that create hot spots and can result in unwanted tissue damage during an ablation procedure.
