    摘要: A system and method for determining on a continuous, real-time basis the proximity of the esophagus to an endocardial catheter during mapping, ablation or other endocardial catheter-based procedures, comprising an esophagus probe catheter and an endocardial catheter adapted for proximal signal transmission between each other. A signal processing unit is included to process and compare a characteristic of the proximity signal that is changes or attenuates with distance between the two catheters, such as impedance, amplitude and/or phase. Audio and/or optical outputs are provided to alert an operator when the distance between the catheters changes or is below a baseline measurement to avoid damage to the esophagus by the endocardial catheter. The system and method may include adaptations of the catheters with location sensor, and a mapping/navigational system for nonfluoroscopic location determination of the catheters.

    摘要: A system for determining the proximity of the esophagus to the ablation electrode of an ablation catheter during an ablation procedure is disclosed. The system comprises an ablation catheter having at least one ablation electrode, an esophageal probe catheter having at least one electrode, and a signal processing unit. Both the ablation electrode and the esophageal probe catheter are electrically connected to the signal processing unit. The signal processing unit receives electrical signals from the ablation electrode on the ablation catheter and the electrode on the esophageal probe catheter and compares the signals to determine the proximity of the esophagus to the ablation electrode.

    摘要: An esophageal mapping catheter enables a physician to map the location of the esophagus so as to avoid damaging the esophagus during radio frequency (RF) ablation procedures. Information from the esophageal mapping catheter is communicated to a patient information unit, communications unit and/or electroanatomic mapping system. The electroanatomic mapping system uses the information from the esophageal mapping catheter to develop a three-dimensional map of the esophagus and to monitor the temperature within the esophagus in order to prevent the creation of esophageal fistula.

    摘要: An esophagus isolation catheter for deflecting an esophagus of a patient away from an ablation site in the left atrium of the patient's heart is provided. The catheter comprises an elongated catheter body and a deflectable section. In one embodiment, the catheter comprises a deflectable intermediate section mounted at the distal end of the catheter body and a generally straight tip section mounted at the distal end of the intermediate section. In this embodiment, the catheter comprises two puller wires, one anchored proximal the other. The intermediate section deflects to form a generally C-shaped curve. In an alternative embodiment, the catheter comprises a deflectable tip section mounted at the distal end of the catheter body. In this embodiment, the catheter comprises only one puller wire. The tip section carries a tip electrode having an atraumatic design to prevent damage to the esophagus upon deflection.
