ELECTROPHYSIOLOGY CATHETER WITH A BULLSEYE ELECTRODE

摘要

An electrode catheter for cardiac electrophysiology is provided. An elongated body (11) suitable for intravascular insertion and forming an axial lumen (15) is provided. A tip electrode (31) defines an axial hole extending inward from a distal end of the tip electrode and is directly mounted to a distal end of the elongated body on a proximal end of the tip electrode. An eye electrode (30) is located within the axial hole substantially concentric to and electrically insulated from the tip electrode. Electrode lead wires (19) run through the axial lumen. One of the electrode lead wires is electrically connected to the eye electrode and another of the electrode lead wires is electrically connected to the tip electrode.
