Title:
ABLATION CATHETER DESIGNS AND METHODS WITH ENHANCED DIAGNOSTIC CAPABILITIES
Document Type and Number:
Japanese Patent JP2018089383
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide segmented ring electrodes.SOLUTION: The segmented electrodes can be constructed at the tip of a catheter or more proximally located. Tip electrodes 3 can be constructed from an electrically insulative substrate covered with a conductive material. The conductive material can be deposited on the electrically insulative substrate to form a single tip electrode or multiple segmented electrodes. In some embodiments, the tip electrode can include irrigation flow holes for irrigation. A method of manufacturing a tip electrode comprising a thin layer of a conductive material deposited on an electrically insulative substrate is disclosed. Segmented ring electrodes 5 can be constructed from segmented ring electrodes that can be equally spaced around a circumference of a catheter. The segmented ring electrodes can be formed into segmented electrode subassemblies that can then be joined to a catheter shaft 2.SELECTED DRAWING: Figure 1
