Title:
２次元可視化における多重電極識別及び配向のための識別可能な電極を有する灌注電気生理学的カテーテル
Document Type and Number:
Japanese Patent JP7305541
Kind Code:
B2
Abstract:
An electrophysiology catheter is disclosed having a balloon with a membrane. Electrodes may be disposed on the membrane. Each electrode may include a radiopaque marker. The markers may have different forms, e.g., alphanumeric or polygonal, to facilitate visualization of the electrodes using a bi-stable image and allow for selection of the appropriate electrodes to be energized during ablation of tissue. The inventive subject matter allows for proper orientation of electrodes on the balloon under a two-dimensional imaging system. This allows the operator or physician to determine if certain electrodes are adjacent or contiguous to the posterior surface of the left atrium and ablate such posterior surface for shorter duration or at a lower power to create an effective transmural lesion on the posterior wall of the left atrium while reducing the chances of damaging the adjacent anatomical structures.
