The invention discloses a
coronary sinus space bend mapping
electrode catheter. In order to solve the technical problem that the operating difficulty is reduced, the
coronary sinus space bend mappingelectrode
catheter is provided with a
catheter body, a
handle device and a connector from the far end to the near end in sequence, wherein the catheter body is provided with an end
electrode, a double-hole tube and a main catheter body starting from the far end in sequence, and the end
electrode, the double-hole tube and the main catheter body are connected in sequence. The double-hole tube is made from block polyether
amide resin or
polyurethane or block
polyamide or nylon, and a pull line steel wire is connected between the end electrode and the
handle device. Compared with the prior art, the far end of the catheter body is bent into an L-shaped annular plane, and an angle is formed between the L-shaped annular plane and the catheter body so that the electrode at the far end of the catheter body can easily enter the orifice of the
coronary sinus, the electrode is closely attached to the inner wall of the coronary sinus, and it is ensured that in the operating process, the electrode does not slide out of the orifice of the coronary sinus. Through computer three-dimensional
cardiac electrophysiology mapping data, the chambers of the heart of a patient can be directly and quickly subjected to three-dimensional imaging, three-
dimensional modeling is completed, the operating effectiveness and
operability are greatly improved clinically, and the
operating time is saved.
